PCS cushion

Sakagami PCS-Cushion Seals absorb shock at the stroke end, reducing impact noise and preventing cylinder damage. Unlike conventional cushion systems, PCS seals require no check valves, simplifying maintenance. Designed for basic pneumatic cylinders, they offer efficient end-of-stroke damping with easier serviceability and reliable performance.
