SMC CDQ2B40-75DM Compact Pneumatic Cylinder 40mm Bore 75mm Stroke 145 PSI

SMC CDQ2B40-75DM Compact Pneumatic Cylinder 40mm Bore 75mm Stroke 145 PSI

The SMC CDQ2B40-75DM is a double-acting compact pneumatic cylinder from SMC's CQ2/CDQ2B series. With a 40mm bore and 75mm stroke, it converts compressed air pressure into linear mechanical force and is built around a compact, space-saving profile suited for automation equipment with limited installation room. This unit includes an attached foot bracket and two push-in (one-touch) pneumatic fittings.

Applications

SMC's CDQ2B series compact cylinders are a widely used standard actuator in factory automation, assembly machinery, pick-and-place systems, clamping fixtures, and semiconductor and electronics manufacturing equipment. The 40mm bore size delivers moderate clamping and pushing force suitable for light to medium-duty actuation tasks. The compact profile is designed for installations where space is tight and a full-size NFPA-style cylinder won't fit. These cylinders are commonly found in robotic end-of-arm tooling, conveyor divert mechanisms, and machine guarding systems. SMC is one of the world's largest pneumatics manufacturers, and CQ2-series cylinders remain a current, actively produced product family — replacement parts, seals, and compatible valves are readily available.
