SMC has redesigned the CQ2 compact cylinder with a new body, making it possible to mount auto switches on any of the 4 surfaces, depending on the installation conditions. Auto switch mounting grooves have replaced the CQ2s mounting rails, preventing projection of auto switches and improving ease and safety of work.Double acting, single rod, compact cylinder, Bore sizes *: 12, 16, 20, 25,

The CQ2 compact cylinder is the world's best selling pneumatic cylinder and is supported globally. The CQ2 is available in 15 bore sizes from 12mm to 200mm. It comes standard with male or female piston rod threads. 42 standard options make it one of the most versatile cylinder series on the market. For mounting flexibility, it is possible to mount auto switches on any of the 4 surfaces.
