    A metal rod scraper Standard equipmentResistance against welding process spatter and other external contaminants is achieved by providing a metal rod scraper as standard.

    Manual override for unlocking for emergencyEven if the air supply is blocked or exhausted, lock release is possible. The fail safe mechanism locks again when the manual override is released.

    Design minimizes the influences of unlocking air qualityA construction which is strong against moisture and drainage in the compressed air has been realized by separating the locking mechanism and the unlocking chamber.

    Can be locked in both directionsAll equal holding force can be obtained on either reciprocating stroke of the cylinder.

    High locking efficiencyGreater 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 0.25 MPa 0.05 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.

    High reliability and stable holding forceOutstanding 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).

    Precautions on Model Selection

    Caution1. 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.

    2. 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.

    3. The following selection example and procedures are based on use at the intermediate stop (including emergency stops during the operation). However, when the cylinder is in the locked state, kinetic energy does not act upon it. Under these conditions, use the load mass at the maximum speed (V) of 100 mm/s shown in graphs 5 to 7 on page 955 depending on the operating pressure and select models.

    Find the maximum load speed: V (mm/s) from the load movement time: t (s) and the movement distance: st (mm).

    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.

    Example)

    CylinderstrokeMovement distance

    of load

    Step (1): From graph (1) find the maximum movement speed of the load Maximum speed V: 280 mm/s

    Step (2): Select Graph(6) based upon the load condition and operating pressure, and then from the intersection of the maximum speed V = 280 mm/s found in Step (1), and the load mass m = 320 kg 140 select a CNS140 or larger bore size.

    Load mass: m = 320 kg Movement distance: st = 400 mm Movement time: t = 2 s Load condition: Vertical downward = Load in direction of rod extension Operating pressure: P = 0.4 MPa
