1 ylinder with Lock Series ø, ø, ø, ø, ø Suitable 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. aper ring P R R Steel ball f θ LJ LM LG1 L1 MLG G M S LS L RL ML1 igh 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 SM products) In addition, both alignability and stable locking force with respect to piston rod eccentricity are obtained by allowing the taper ring to float. Manual override for unlocking Even if the air supply is blocked or exhausted, lock release is possible. he fail safe mechanism locks again when the manual override is released. igh 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 SM product).

2 Series Model Selection Precautions on Model Selection arning 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. he 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) Movement distance of load ' ylinder stroke Step (1) Graph (1) Load movement time: t (S) st st st st st st st st 3st st 3 st st [Example] st st ind the maximum load speed. ind the maximum load speed: (mm/s) from the load movement time: t (s) and the movement distance: st..1 3 Maximum speed: (mm/s) 3. he following selection example and procedures are based on use at the intermediate stop (including emergency stops during the operation). owever, when the cylinder is in the locked state such as drop prevention, kinetic energy does not act upon it. Under these conditions, use the load mass at the maximum speed () of mm/s shown in graphs to on page depending on the operating pressure and select models. Selection Example Step () ind 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 line above the point of intersection.

7 ylinder with Lock Double cting, Single Rod Series onstruction Principle Steel ball all retainer rake shoe rake shoe holder rake spring aper ring rake piston ir pressure supply ir pressure exhaust Unlocked state Locked state Spring locking (Exhaust locking) he spring force which acts upon the taper ring is magnified by a wedge effect, and is conveyed to all of the numerous steel balls which are arranged in two circles. hese act on the brake shoe holder and brake, which lock the piston rod by tightening against it with a large force. Unlocking is accomplished when air pressure is supplied to the unlocking port. he brake piston and taper ring oppose the spring force, moving to the left side, and the ball retainer strikes the cover section. he braking force is released as the steel balls are removed from the taper ring by the ball retainer.

30 Series Specific Product Precautions 1 e sure to read before handling. Refer to front matters and 3 for Safety Instructions and pages 3 to for ctuator and uto Switch Precautions. Design of Equipment and Machinery arning 1. onstruct 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 (page 3) should be used. Selection arning 1. hen 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.. onsider stopping accuracy and the amount of over-run 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. he cylinder stroke resulting from this delay is the overrun amount. he 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. he limit switch must have a detection length (dog length) of the overrun amount + α. or SM s auto switches, the operating range is between and mm. (It varies depending on a switch model.) hen the overrun amount exceeds this range, selfholding of the contact should Stop signal be performed at the switch load side. or stopping accuracy, refer to page. mount of overrun 3. 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. o 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. Selection arning. ote that the stopping accuracy will be influenced by changes in piston speed. hen 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. herefore, 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.. he holding force (max. static load) indicates the maximum capability to hold a static load without loads, vibration and impact. his 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. he Model Selection (pages and ) is based on use at the intermediate stop (including emergency stops during the operation). owever, 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 () of mm/s shown in the graphs to on page depending on the operating pressure and select models. arning Mounting 1. e 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, etc. may operate on the piston rod and cause damage to the lock mechanism. 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. his can be accomplished by simply connecting an air line to the unlocking port and supplying air pressure of. MPa or more. aution 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. hen there is a large discrepancy, the piston rod may be subjected to uneven wear or damage due to the inertial moment during locking stops. Load center of gravity and cylinder shaft center are not matched.

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.. Use a solenoid valve for unlocking which has a large effective area, as a rule % or more of the effective area of the cylinder drive solenoid valve. he larger the effective area is, the shorter the locking time will be (the overrun amount will be shorter), and stopping accuracy will be improved. 3.
