A maximum speed of 500 mm/s is possible if the piston is locked in the stationary state for the purpose of drop prevention. Make sure that the piston speed does not exceed 200 mm/s during locking. . The cylinder can be used to 1/2 of its holding force or below if only a stationary load is applied, such as for drop prevention. A style of Series CA1 (o40 to o100) and Series CS1 (o125 to o160) air cylinder, this is a bi-directional locked-up cylinder in which two uni-directional locked-up units have been assembled by facing them away from each other. Maximum operating pressure Minimum operating pressure Action Piston speed .
