Applicable Series Description Model Action Note Standard type CM2 Double acting, Single rod Non-rotating rod type CM2K Double acting, Single rod Except with air cushion Direct mount type CM2R Double acting, Single rod Except with air cushion Direct mount, Non-rotating rod type CM2RK Double acting, Single rod Specifications: Same as standard type * Please contact SMC for each manufacturable stroke length. * The D-A3lA/A44A/G39A/K39A/ B54/B64 cannot be mounted on bore sizes o20 and o25 cylinder with air cushion. Double output is possible. 2) Double output When the air pressure is supplied to the A and C ports at the same time, the double output can be obtained in the stroke A range. 1) Initial state (0 stroke position) Stroke B operation 2) Operation When the air pressure is supplied from the C port, the rod operates the stroke B. 1) Initial state (0 stroke position) Stroke A operation Functional description of dual stroke cylinder Stroke A or Stroke B operation can be made individually. 4) Cylinder retraction When the air pressure is supplied from the B port, the rod retracts completely. 3) 2nd stage (Stroke B-A operation) Following the 1st stage, when the air pressure is supplied from the C port, the rod operates the stroke B-A. 2) Operation When the air pressure is supplied from the A port, the rod operates the stroke A. 1) Initial state (0 stroke position) 2) 1st stage (Stroke A operation) When the air pressure is supplied from the A port, the rod operates the stroke A. 1) Initial state (0 stroke position) (mm) Bore size SA SB ZZ 20 48 62 164 25 48 62 168 32 50 64 172 40 67.5 88.5 222 Precautions 1.
