2 CL Series Specific Product Precautions e sure to read this before handling the products. The precautions on these pages are for the fine lock cylinders and the lock-up cylinders. Refer to back page for Safety Instructions. For general actuator precautions, refer to ctuator Precautions on pages 3 to. Design of Equipment and Machinery Warning. Construct so that the human body will not come into direct contact with driven objects or the moving parts of locking cylinders. If there is a risk of contact, provide safety measures such as a cover or a system that uses sensors that will activate an emergency stop before contact is made.. Use a balance circuit in which lurching of the piston is taken into consideration. If the lock is applied at a desired position of a and compressed air is applied to only one side of the cylinder, the piston will lurch at a high speed the moment the lock is disengaged. In such a situation, there is a risk of injury to humans, or equipment damage. To prevent the piston from lurching, use a balance circuit such as the recommended pneumatic circuit (P. ). If an air-hydro fine lock cylinder is used, make sure to operate the lock portion through air pressure. Never use oil on the lock-up cylinder because the lock-up cylinder is a non-lube type. Failure to observe this could cause the lock to malfunction. Selection Warning Refer to the following criteria for the maximum load in the locked state, and set. Holding force (maximum static load) means the maximum capability of holding a static load that is not accompanied by vibration or impact under the condition that no load is applied. Therefore, it does not refer to a load that cannot be held constantly. To ensure braking force, the maximum load must be set as described below.. For constant static loads, such as for drop prevention: Fine lock series (CLJ/CLM/CLG series) % or less of the holding force (maximum static load) Note) For applications such as drop prevention, consider situations in which the air source is shut off, and make selections based on the holding force of the spring locked state. Do not use the pneumatic lock for drop prevention purposes. Lock-up series (CL series) % or less of the holding force (maximum static load). When kinetic energy acts upon the cylinder in a locked state, such as when effecting an intermediate stop, there are constraints in terms of the allowable kinetic energy. Therefore, refer to the allowable kinetic energy of the respective series. Furthermore, during locking, the mechanism must sustain the thrust of the cylinder itself, in addition to absorbing the kinetic energy. Therefore, even within a given allowable kinetic energy level, there is an upper limit to the amount of the load that can be sustained. Fine lock series (CLJ/CLM/CLG series) Maximum load at horizontal mounting: % or less of the holding force (Maximum static load) for spring lock Maximum load at vertical mounting: % or less of the holding force (Maximum static load) for spring lock Lock-up series (CL series) Maximum load at horizontal mounting: % or less of the holding force (Maximum static load) Maximum load at vertical mounting: % or less of the holding force (Maximum static load) 3. In a locked state, do not apply impacts, strong vibrations or rotational forces. Do not apply a impacts, strong vibrations or rotational forces from external sources, because this could damage or shorten the life of the lock unit.. The locking of the fine lock cylinder is directional. lthough the fine lock cylinder can be locked in both directions, be aware that its holding force is smaller in one of the directions. CLJ/CLM/CLG Holding force at piston rod extended side decreases approx. %.. The locking of the lock-up cylinder is unidirectional. ecause the locking direction of the lock-up cylinder is unidirectional, select the locking direction in accordance with the particular operating conditions. It is also possible to manufacture a bidirectional lock-up cylinder. For details, refer to Made to Order on page. Due to the nature of its construction, a lock-up cylinder has a play of approximately. mm to mm in the axial direction. Therefore, if an external stopper is used to stop the piston rod and the lock is engaged, the piston rod will shift in the amount of its axial play.. To effect an intermediate stop, take the cylinder s stopping precision and overrun amount into consideration. ecause the lock is applied by mechanical means, the piston will not stop immediately in response to a stopping signal, but only after a time lag. This lag determines the amount of the overrun of the piston. Thus, the range of the maximum and minimum amounts of the overrun is the stopping precision. Place the limit switch before the desired stopping position, only in the amount of the overrun. The limit switch must have a detection length (dog length) of the overrun amount + α. For SMC s auto switches, the operating range are between and mm. (It varies depending on a switch model.) When the overrun amount exceeds this range, self-holding of the contact should be performed at the switch load side. For stopping accuracy, refer to CLJ series (P. 3), CLM series (P. ), CLG series (P. ), and CL series (P. 3) respectively. Stop signal Overrun amount. In order to further improve stopping accuracy, the time from the stop signal to the operation of the lock should be shortened as much as possible. To accomplish this, use a device such as a highly responsive electric control circuit or solenoid valve driven by direct current, and place the solenoid valve as close as possible to the cylinder.. e aware that the stopping accuracy is influenced by changes in the piston speed. The variance in the stopping position increases if the piston speed changes, such as due to load fluctuations during the reciprocal movement of the piston. Therefore, take measures to ensure a constant piston speed immediately preceding the stopping position. Furthermore, the variances in the stopping position increases when the piston is effecting a cushioning or during acceleration after starting its movement.. When unlocking is performed, if the thrust is applied to the piston, unlocking will not be easily done. To avoid that, ensure that unlocking should be performed before the thrust is applied to the piston.

3 CL Series Specific Product Precautions e sure to read this before handling the products. The precautions on these pages are for the fine lock cylinders and the lock-up cylinders. Refer to back page for Safety Instructions. For general actuator precautions, refer to ctuator Precautions on pages 3 to. Mounting Warning. e certain to connect the rod end to the load with the lock released. If this is performed with the lock engaged, a load that exceeds the allowable rotational force or holding force would be applied to the piston rod, which could damage the locking mechanism. The fine lock and CL series with to cylinders have a built-in manual unlocking mechanism. Therefore, they can be maintained in the unlocked state without supplying air. However, it is recommended that the piping is connected to the unlocking port, an air pressure of.3 MPa or more is supplied, and the work is performed in the unlocked state. For CL series with to cylinders, simply connect piping to the lock-up port, and supply air pressure of. MPa or more to disengage the lock in order to attach a load. Caution. Do not apply offset loads on the piston rod. Pay particular attention to aligning the center of gravity of the load with the axial center of the cylinder. If there is a large amount of deviation, the piston rod could become unevenly worn or damaged due to the inertial moment that is created when the piston rod is stopped by the lock. djustment Caution. Place it in the locked position. (Excluding the CL series to.) The locks are manually disengaged at the time the cylinders are shipped from the factory. Therefore, make sure to change them to the locked state before using the cylinders. For procedures to effect the change, refer to page for the fine lock series. e aware that the lock will not operate properly if the change is not performed correctly. djust the cylinder's air balance. In the state in which a load is attached to the cylinder, disengage the lock and adjust the air pressure at the rod side and the head side of the cylinder to obtain a load balance. y maintaining a proper air balance, the piston rod can be prevented from lurching when the lock is disengaged.. djust the mounting position of detections such as those of the auto switches. To effect an intermediate stop, adjust the mounting position of the auto switch detection by taking the amount of overrun into consideration in relation to the desired stopping position.

4 CL Series Specific Product Precautions 3 e sure to read this before handling the products. The precautions on these pages are for the fine lock cylinders and the lock-up cylinders. Refer to back page for Safety Instructions. For general actuator precautions, refer to ctuator Precautions on pages 3 to. W Warning. e certain to use an pneumatic circuit which will apply balancing pressure to both sides of the piston when in a locked stop. In order to prevent cylinder lurching after a lock stop, when restarting or when manually unlocking, a circuit should be used to which will apply balancing pressure to both sides of the piston, thereby canceling the force generated by the load in the direction of piston movement.. The effective area of the lock release solenoid valve should be at least % of the effective area of the cylinder driving solenoid valve, and it should be installed as close to the cylinder as possible so that it is closer than the cylinder driving solenoid valve. If the effective area of the lock release solenoid valve is smaller than the cylinder driving solenoid valve or if it is installed at a distance from the cylinder, the time required for exhausting air for releasing the lock will be longer, which may cause a delay in the locking operation. The delay in the locking operation may result in problems such as increase of overrunning when performing intermediate stop or emergency stop during operation, or if maintaining position from the operation stop state such as drop prevention, workpieces may be dropped depending on the timing of the load action to the operation delay of the lock. 3. void backflow of the exhaust pressure when there is a possibility of interference of exhaust air, for example for a common exhaust type valve manifold. The lock may not operate properly when the exhaust air pressure backflows due to interference of the exhaust air when exhausting air for lock release. It is recommended to use an individual exhaust type manifold or individual valves.. llow at least. seconds from a locked stop (intermediate stop of the cylinder) until release of the lock. When the locked stop time is too short, the piston rod (and load) may lurch at a speed greater than the control speed of the speed controller.. When restarting, control the switching signal for the unlocking solenoid valve so that it acts before or at the same time as the cylinder drive solenoid valve. If the signal is delayed, the piston rod (and load) may lurch at a speed greater than the control speed of the speed controller.. Carefully check for dew condensation due to repeated air supply and exhaust of the locking solenoid valve. The operating of the lock part is very small. So, if the piping is long and the air supply and exhaust are repeated, the dew condensation caused by the adiabatic expansion accumulates in the lock part. This may corrode internal parts, causing air leak or lock release fault.. asic circuit ) [Horizontal] Forward ackward 3 port normally closed SOL. SOL.C Regulator with check valve Pressure center SOL.

Caution Caution when Locking Holding force (maximum static load) means the maximum capability of holding a static load that is not accompanied by vibration or impact under the condition that no load is applied. Therefore, it does not refer to a load that cannot be held constantly. When using (selecting) this product, carefully check the following points. If the piston rod slips because the lock s holding force has been exceeded, the brake shoe could be damaged, resulting in a reduced holding force or shortened life. The upper limit of the load that is used under the conditions not associated with the kinetic energy when locking, such as drop prevention must be % or less of the holding force. Do not use the cylinder in the locked state to sustain a load that involves impact. 3 D- -X

In terms of specific load conditions, the allowable kinetic energy indicated in the table above is equivalent to a % load ratio at. MPa, and a piston speed of 3 m m / s e c. T h e r e fo r e, i f t h e operating conditions are below these values, calculations are unnecessary.. pply the following formula to obtain the kinetic energy of the load. Ek: Kinetic energy of load (J) m: Load mass (kg) υ: Piston speed (m/s) 3. The piston speed will exceed the average speed immediately before locking. To determine the piston speed for the purpose of obtaining the kinetic energy of load, use. times the average speed as a guide.. The relation between the speed and the load of the respective tube bores is indicated in the diagram below. Use the cylinder in the range below the line.. Even within a given allowable kinetic energy level, there is an upper limit to the size of the load that can be sustained. Thus, a horizontally mounted cylinder must be operated below the solid line, and a vertically mounted cylinder must be operated below the dotted line.

Holding Force of Spring Locking (Maximum static load) Holding force (N) ore size ir pressure applied to pressurized locking port (MPa) When selecting cylinders, refer to the Precautions and allowable kinetic energy when locking on page, and then select a cylinder. Caution Caution when Locking Holding force (maximum static load) means the maximum capability of holding a static load that is not accompanied by vibration or impact under the condition that no load is applied. Therefore, it does not refer to a load that cannot be held constantly. When using (selecting) this product, carefully check the following points. If the piston rod slips because the lock s holding force has been exceeded, the brake shoe could be damaged, resulting in a reduced holding force or shortened life. Do not use the cylinder in the locked state to sustain a load that involves impact. The upper limit of the load that is used under the conditions not associated with the kinetic energy when locking, such as drop prevention must be % or less of the holding force. Caution Operating Precautions Install a rod boot without twisting. If the cylinder is installed with its bellows twisted, it could damage the bellows.

36 CLG Series Caution/llowable Kinetic Energy when Locking ore size llowable kinetic energy (J) In terms of specific load conditions, the allowable kinetic energy indicated in the table above is equivalent to a % load ratio at. MPa, and a piston speed of 3 mm/sec. Therefore, if the operating conditions are below these values, calculations are unnecessary.. pply the following formula to obtain the kinetic energy of the load. Ek: Kinetic energy of load (J) m: Load mass (kg) υ: Piston speed (m/s) (verage speed x. times) 3. The piston speed will exceed the average speed immediately before locking. To determine the piston speed for the purpose of obtaining the kinetic energy of load, use. times the average speed as a guide.. The relation between the speed and the load of the respective tube bores is indicated in the diagram below. Use the cylinder in the range below the line.. Even within a given allowable kinetic energy level, there is an upper limit to the size of the load that can be sustained. Thus, a horizontally mounted cylinder must be operated below the solid line, and a vertically mounted cylinder must be operated below the dotted line. Load mass (kg) 3 Piston speed (mm/s) Holding Force of Spring Locking (Maximum static load) ore size 3 3 Holding force (N) 3 3 Note) Holding force at piston rod extended side decreases approximately %. Holding Force of Pneumatic Locking (Maximum static load) Holding force (N) ir pressure applied to pressurized locking port (MPa) When selecting cylinders, refer to the Precautions and allowable kinetic energy when locking on page, and then select a cylinder. Caution Caution when Locking Holding force (maximum static load) means the maximum capability of holding a static load that is not accompanied by vibration or impact under the condition that no load is applied. Therefore, it does not refer to a load that cannot be held constantly. When using (selecting) this product, carefully check the following points. If the piston rod slips because the lock s holding force has been exceeded, the brake shoe could be damaged, resulting in a reduced holding force or shortened life. The upper limit of the load that is used under the conditions not associated with the kinetic energy when locking, such as drop prevention must be % or less of the holding force. Do not use the cylinder in the locked state to sustain a load that involves impact. Stopping ccuracy (Not including tolerance of control system.)

Operating Precautions Warning. Do not operate the cushion valve in the fully closed or fully opened state. Using it in the fully closed state will cause the cushion seal to be damaged. Using it in the fully opened state will cause the piston rod assembly or the cover to be damaged.. Operate within the specified cylinder speed. Otherwise, cylinder and seal damage may occur. 3. Carefully check the cushion performance in a low speed range. The performance and effect at around mm/s may vary depending on the individual difference of each product.. If a cylinder is actuated at high speed when mounted with one side fastened and one side free (basic type, flange type, direct mount type), the bending moment may act on the cylinder due to vibration at the end, causing damage to the cylinder. In such cases, install a mounting bracket to suppress vibration of the cylinder body, or reduce piston speed until the cylinder body does not vibrate at the end. lso, use a mounting bracket when moving the cylinder body, or mounting a long cylinder horizontally with one-sided fastening. Caution. Install a rod boot without twisting. If the cylinder is installed with its bellows twisted, it could damage the bellows..

However, the lock-up direction can be changed easily. To change the direction, pay particular attention to the following steps: Loosening the tie-rods for the purpose of changing the direction could also loosen the nuts on the cylinder side. Therefore, before assembling the unit, make sure to verify that the nuts on the cylinder are not loose. Retighten the nuts if they are loose, and while turning the piston rod, apply a low pressure of. MPa to make sure that it operates smoothly in both the extending and retracting directions.. Loosen the tie-rod nuts and pull out the four tie-rods. Spring Locked-up ring Piston rod operating direction 3. Turn the unit to the opposite end so that the end without the scraper is facing the cylinder rod cover. Then, securely insert the unit into the end boss portion of the rod cover.. Install four tie-rods, with their shorter threaded portion oriented towards the rod cover, and tighten them with uniform torque. Until the installation and adjustment have been completed, never pull out the unlocking bolt (or release the air pressure). The processes described above complete the changing of the locked-up direction. efore using the cylinder, make sure that the lock-up operates properly. ir pressure exhaust ir pressure supply Piston rod operating direction. pply air pressure of.

Open the rubber cap and screw in the unlocking bolt, which is provided as an accessory part. t this time, apply air pressure of. MPa to.3 MPa to disengage the lock and insert the bolt. (The operation to follow can be performed properly and easily with the application of air pressure.) fter verifying that the bolt has been inserted properly, pull out the unit from the rod. Then, loosen the three screws in the scraper presser plate to remove the presser plate and the scraper. Install the scraper and the presser plate, in that order, on the opposite side. to. Loosen the tie-rod nuts and pull out the four tie-rods. Tie-rod End boss. Install the four tie-rods, with their shorter threaded portion oriented towards the rod cover, and tighten them with uniform torque. Maintain the application of air pressure until the installation and adjustment have been completed, and never actuate the lock in the meantime. ir pressure supply Caution When the lock-up unit is not secured by the tie-rods, the air pressure applied to the lock-up port should be between. MPa and.3 MPa. Never supply a higher air pressure as it could lead to equipment damage. 33 D- -X

50 CL Series Warning. Do not unlock manually until the safety is confirmed.. Perform the unlocking after the residual pressure inside the system has been exhausted. 3. Take measures to prevent the load from dropping when unlocking is performed. Perform work with the load in its lowest position. Take measures for drop prevention by strut, etc. Manual Lock Release ( to ) To manually disengage the lock, perform the following steps:. Open the rubber cap.. pply. MPa to.3 MPa of air pressure to the locking port, and bring the tilted ring upright. 3. Screw a bolt of an appropriate length into the ring tap. The bolt size is M for and, and M for 3,, and. Caution During installation adjustment, perform the operation by applying air pressure only to the lock-up port. Caution The lock is manually disengaged at the time the cylinder is shipped from the factory. ecause the lock will not operate in this state, make sure to change it to the locked state before operation, after having adjusted the axial center for installation. (Only to ) olt Lock-up port Cap to (On cylinders to, the lock cannot be disengaged manually.) Caution Recommended Pneumatic Circuit/Caution on Handling For Selection/recommended pneumatic circuit, stopping accuracy and caution on handling, refer to pages to. Caution Caution Caution Stopping ccuracy Caution on Handling Recommended Pneumatic Circuit. Load fluctuations during the reciprocal movement of the piston could cause the piston speed to change. change in the piston speed could greatly increase the variance in the piston s stopping position. Therefore, take appropriate measures so that the piston speed becomes constant during the piston's reciprocal movement, particularly just before stopping.. During a cushioning, or when the piston is in the acceleration region following the start of its travel, there is a large change in speed. Thus, the variance in the stopping position will also be large. Therefore, when effecting a step movement in which the from the start of the operation to the next position is short, be aware of the possibility of being unable to attain the accuracy. 3. Precautions regarding lock-up after the piston has been stopped with an external stopper: To apply the lock-up after the piston has been stopped by an external stopper other than the locked-up mechanism, including stoppage by the end of the cylinder, be aware of the matters described below. Due to the nature of the lock-up mechanism, there is an axial play of about. to. mm. Furthermore, due to pipe routing conditions, if it takes longer for the air to discharge through the lock-up port than for the balance pressure to stabilize, causing a delay in locking, the piston rod will move for an amount that is equivalent to the play + delay. Piston speed over mm/s (When locking). Immediately before a lock stop, drop the piston speed to mm/s or lower by switching the speed controller (to the bypass circuit). Then, operate the lock-up. 3. Flushing efore piping is connected, it should be thoroughly blown out with air (flushing) or washed to remove cutting chip, cutting oil and other debris from inside the pipe.. The load on the piston rod Use the cylinder in the state in which the load to the piston rod is always applied in the axial direction. This must be more strictly adhered to than with ordinary air cylinders. Furthermore, use a guide to control the movement of the load so as not to cause chatter or twist. 3. rotational force against the piston rod void applying a rotational force against the piston rod. In particular, the application of a rotational force must be prevented when in a lock-up state.. Protecting the sliding portion of the rod Use caution that no scratch or dent will be given to the slide part of the guide rod, as this could damage the seals and lead to leaks or faulty lock-up.. Lubrication It is not necessary to lubricate the CL series because it is the non-lube type. Never lubricate it because doing so will cause faulty lock-up. For recommended pneumatic circuits, refer to page.. Operating the pneumatic circuit Instead of the current reciprocal air cylinder circuit, use an pneumatic circuit, such as the recommended circuit, in which measures are taken to prevent the piston from lurching after the lock-up has been disengaged.. Lock-up direction The lock-up is unidirectional. The locking direction is in accordance with the position of the lock-up port, as shown in the figure below. Lock-up unit Cylinder Extension locking Lock-up port Retraction locking to For cylinders to, verify the portion that is stamped on the cap of the lock. 3. Maximum speed and maximum load Never lock up a cylinder that involves a kinetic energy that exceeds the maximum speed or the maximum load indicated in the specifications.
