1 ylinder with Lock M Series ø, ø, 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 aper ring 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. P Maximum piston speed: mm/s It can be used at to mm/s provided that it is within the allowable kinetic energy range. 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. LJ LM LG L MLG G M S LS L RL MLU MLGP ML 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 M Series Model Selection Precautions on Model Selection aution. In order that the originally selected maximum speed shall not be 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) ' Step () st st st st st st st st st st [Example].... st st 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. Graph () Load movement time: t (S). Movement distance of load ylinder stroke Maximum speed: (mm/s). he following selection example and procedures are based on use at the intermediate stop (including emergency stops during 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 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 () and the load mass. Select the bore size on the above the point of intersection.

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 right 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.

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. arning Selection. 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. ue 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. SM s auto switches have operating ranges from to mm (depending on the auto switch model). hen the overrun amount exceeds this range, self-holding of the contact should be performed at the auto switch load side. or stopping accuracy, refer to page. arning arning 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. 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.. 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 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 graphs () to () on page depending on the operating pressure and select models. Mounting. 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. M 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.. o 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.

Pneumatic ircuit arning. e certain to use an pneumatic circuit which will. asic circuit apply balancing pressure to both sides of the piston when in a locked stop. ) [orizontal] In order to prevent cylinder lurching after a lock stop, when orward 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 ackward in the direction of piston movement.. he 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. he 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. he lock may not operate properly when the exhaust air pressure backflows due to interference of the exhaust air when exhausting air for lock release.
