1 Cylinder with Lock Series ø, ø, ø, ø locking cylinder ideal for intermediate stops, emergency stops and drop prevention. Simple construction force magnifying mechanism is employed based on the wedge effect of the taper ring and steel balls. Steel ball f R R Taper ring High locking efficiency Greater locking efficiency as well as stable locking and unlocking operation has been achieved by arranging a large number of steel ball bearings in circular rows. (Unlocking pressure of. MPa. MPa lower than conventional SMC products) In addition, both alignability and stable locking force with respect to piston rod eccentricity are obtained by allowing the taper ring to float. P Manual override for unlocking Even if the air supply is blocked or exhausted, lock release is possible with a simple tool. The fail safe mechanism locks again when the manual override is released. FREE CLJ CLM CLG1 CL1 MLGC MNB CN CNS CLS CLQ RLQ MLU MLGP ML1C High reliability and stable holding force Outstanding durability and stable holding force are maintained by the use of a brake shoe having superior wear resistance, which has also been substantially lengthened (double the conventional SMC product). Series Variations Series ction Cushion type Rubber bumper ir cushion With rod boot Lock holding force (N) Design minimizes the influences of unlocking air quality construction which is strong against moisture and drainage in the compressed air has been realized by separating the locking mechanism and the unlocking chamber. Stroke Can be locked in both directions Holding force is equal on either extend or retract. Cylinder with lock series Double acting, Single rod 1 Max. Up to 1 D- -X

2 Series Model Selection Precautions on Model Selection Step (1) Find the maximum load speed V. Caution 1. In order that the originally selected maximum speed is not exceeded, be certain to use a speed controller to adjust the total movement distance of the load so that movement takes place in no less than the applicable movement time. The movement time is the time that is necessary for the load to travel the total movement distance from the start without any intermediate stops.. In cases where the cylinder stroke and the movement distance of the load are different (double speed mechanism, etc.), use the movement distance of the load for selection purposes. Example) V Movement distance of load W V' Cylinder stroke Find the maximum load speed: V (mm/s) from the load movement time: t (s) and the movement distance: st. Graph (1) Load movement time: t (S) st st st st st st st [Example].1 Maximum speed: V (mm/s). The following selection example and procedures are based on use at the intermediate stop (including emergency stops during operation). However, when the cylinder is in a locked state, kinetic energy does not act upon it. Under these conditions, use the load mass at the maximum speed (V) of mm/s shown in graphs () to () depending on the operating pressure and select models. Selection Example Load mass: m = 1 kg Movement distance: st = mm Movement time: t =. s Load condition: Vertical downward = Load in direction of rod extension Operating pressure: P =. MPa Step (1): From graph (1) find the maximum movement speed of the load. Maximum speed V mm/s Step (): Select graph () based upon the load condition and operating pressure, and then from the intersection of the maximum speed V = mm/s found in Step (1), and the load mass m = 1 kg ø select a or larger bore size. Step () Find the bore size. Select a graph based upon the load condition and operating pressure, and then find the point of intersection for the maximum speed found in Step (1) and the load mass. Select the bore size on the above the point of intersection.

These act on the brake shoe holder and brake, which locks the piston rod by tightening against it with a large force. Unlocking is accomplished when air pressure is supplied to the unlocking port. The release piston and taper ring oppose the spring force, moving to the right side, and the ball retainer strikes the cover section. The braking force is released as the steel balls are removed from the taper ring by the ball retainer.

21 Series Specific Product Precautions 1 Be sure to read this before handling the products. Refer to back page for Safety Instructions and pages to 1 for ctuator and uto Switch Precautions. Design of Equipment and Machinery Warning 1. Construct so that the human body will not come into direct contact with driven objects or the moving parts of locking cylinders. Devise a safe structure by attaching protective covers that prevent direct contact with the human body, or in cases where there is a danger of contact, provide sensors or other devices to perform an emergency stop, etc., before contact occurs.. Use a balance circuit, taking cylinder lurching into consideration. In cases such as an intermediate stop, where a lock is operated at a desired position within the stroke and air pressure is applied from only one side of the cylinder, the piston will lurch at high speed when the lock is released. In such situations, there is a danger of causing human injury by having hands or feet, etc. caught, and also a danger for causing damage to the equipment. In order to prevent this lurching, a balance circuit such as the recommended pneumatic circuits (pages and ) should be used. Warning Stop signal Selection 1. When in the locked state, do not apply a load accompanied by an impact shock, strong vibration or turning force, etc. Use caution, because an external action such as an impacting load, strong vibration or turning force, may damage the locking mechanism or reduce its life.. Consider stopping accuracy and the amount of overrun when an intermediate stop is performed. Due to the nature of a mechanical lock, there is a momentary lag with respect to the stop signal, and a time delay occurs before stopping. The cylinder stroke resulting from this delay is the overrun amount. The difference between the maximum and minimum overrun amounts is the stopping accuracy. Place a limit switch before the desired stopping position, at a distance equal to the overrun amount. The limit switch must have a detection length (dog length) of the overrun amount + α. For SMC s auto switches, the operating range is between and 1 mm. (It varies depending on a switch model.) When the overrun amount exceeds this range, selfholding of the contact should be performed at the switch load side. For stopping accuracy, refer to page. mount of overrun Warning Warning Selection. 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.. Note that the stopping accuracy will be influenced by changes in piston speed. When piston speed changes during the course of the cylinder stroke due to variations in the load or disturbances, etc., the dispersion of stopping positions will increase. Therefore, consideration should be given to establishing a standard speed for the piston just before it reaches the stopping position. Moreover, the dispersion of stopping positions will increase during the cushioned portion of the stroke and during the accelerating portion of the stroke after the start of operation, due to the large changes in piston speed.. The holding force (max. static load) indicates the maximum capability to hold a static load without loads, vibration and impact. This does not indicate a load that can be held in ordinary conditions. Select the most suitable bore sizes for the operating conditions in accordance with the selection procedures. The Model Selection (pages and ) is based on use at the intermediate stop (including emergency stops during operation). However, when the cylinder is in a locked state, kinetic energy does not act upon it. Under these conditions, use the load mass at the maximum speed (V) of mm/s shown in graphs () to () on page depending on the operating pressure and select models. Mounting 1. Be certain to connect the rod end to the load with the lock released. If connected in the locked state, a load greater than the turning force or holding force may operate on the piston rod and cause damage to the lock mechanism. The series is equipped with an emergency unlocking mechanism, however, when connecting the rod end to the load this should be done with the lock released by simply connecting an air line to the unlocking port and supplying air pressure of. MPa or more.. When the cylinder is used as mounted with a single side fixed or free (basic type, flange type), a bending moment will be applied to the cylinder due to the vibration generated at the stroke end, and the cylinder may be damaged. In such a case, mount a bracket to reduce the vibration of the cylinder or use the cylinder at a piston speed low enough to prevent the cylinder from vibrating at the stroke end. lso, please use a support bracket when the cylinder body moves or when the long stroke cylinder is fixed horizontally on one side. Caution 1. Install a rod boot without twisting. If the cylinder is installed with its bellows twisted, it could damage the bellows..

22 Series Specific Product Precautions Be sure to read this before handling the products. Refer to back page for Safety Instructions and pages to 1 for ctuator and uto Switch Precautions. Caution Mounting 1. Do not apply offset loads to the piston rod. Particular care should be taken to match the load s center of gravity with the center of the cylinder shaft. When there is a large discrepancy, the piston rod may be subjected to uneven wear or damage due to the inertial moment during locking stops. X Load center of gravity and cylinder shaft center are not matched. Load center of gravity and cylinder shaft center are matched. Note) Can be used if all of the generated moment is absorbed by an effective guide. djustment Warning 1. 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.. 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. Caution 1. djust the cylinder s air balance. Balance the load by adjusting the air pressure in the rod and head sides of the cylinder with the load connected to the cylinder and the lock released. Lurching of the cylinder when unlocked can be prevented by carefully adjusting this air balance.. djust mounting position for detection area of auto switch etc. When intermediate stop is done, adjust the mounting position for detection stop is done, adjust the mounting position for detection area of auto switch etc., with consideration of over-run distance to required stop position. Warning Pneumatic Circuit 1. Be 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 unlocking 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 unlocking solenoid valve is small or if it is installed at a distance from the cylinder, the time required for exhausting air for unlocking 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.. 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 stroke 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.. Basic circuit 1. [Horizontal] W Extension Retraction Pressure center.

W Warning Caution Cylinder internal resistance (N) Manually Unlocking 1. Never operate the unlocking cam until safety has been confirmed. (Do not turn to the FREE side.) a) When unlocking is performed with air pressure applied to only one side of the cylinder, the moving parts of the cylinder will lurch at high speed causing a serious hazard. b) When unlocking is performed, be sure to confirm that personnel are not within the load movement range and that no other problems will occur if the load moves.. Before operating the unlocking cam, exhaust any residual pressure which is in the system.. Take measures to prevent the load from dropping when unlocking is performed. a) Perform work with the load in its lowest position. b) Take measures for drop prevention by strut, etc. 1. The unlocking cam is an emergency unlocking mechanism only. During an emergency when the air supply is stopped or cut off, this is used to alleviate a problem by forcibly pushing back the release piston and brake spring to release the lock.. When installing the cylinder into equipment or performing adjustments, etc., be sure to apply air pressure of. MPa or more to the unlocking port, and do not perform work using the unlocking cam.. When releasing the lock with the unlocking cam, it must be noted that the internal resistance of the cylinder will be high, unlike normally unlocking with air pressure Size Size Size Size. Be sure to operate the unlocking cam on the FREE side (clockwise direction), and do not turn with a torque greater than the maximum cam operating torque.
