Single-rod, double-acting, pneumatic cylinders: the C55 Series Designed to satisfy a wide range of automation machine applications, the C55 Series delivers excellent load performance thanks to its unique elastic damping, piston support ring and rod bushing used throughout the range. In fact, European machine builders looking for a compact ISO cylinder with a stroke length of up to 150mm, while offering the benefits of standardized mounting dimensions, now have the perfect solution.Available with a standard bore of 20, 25, 32, 40, 50, 63, 80 and 100mm, piston speed between 50 and 500mm/sec, these cylinders are designed to operate with relatively low pneumatic pressure, between 0.05 to 1.0 MPa, and operating temperatures from minus 10ºC to plus 70ºC. With mounting options standardized to both ISO 21287 and 6431, this new range of cylinders completes SMC's comprehensive collection of ISO/VDMA-compliant cylinders.
