CP96-C Double Acting Cylinder The SMC CP96-C series double-acting pneumatic cylinders feature both air and bumper cushioning. Using both air and bumper cushioning reduces the length of the cushion stroke reducing cycle time and the noise at the end of the stroke. CP96-C cylinder bodies are grooved on four sides to allow the easy fitting of CNOMO or SMC M9 and A9 position sensors. Sensors can simply be slid into position from either end of the profile actuator body.
