EXPLAINED
RHC, High Power Cylinder, Double Acting, Single Rod
High speed or high load cylinder applications frequently require additional speed and flow control devices to control the stopping of the load. SMC's RHC series features a longer cushion design which is capable of stopping heavy or high speed loads while maintaining the simplicity of a standard air cushion cylinder. This enhanced cushion allows the kinetic distance, which results in the ability to absorb up to 23.8 ft-lb of energy and operate reliably at speeds up to 118 in/sec. Even with the improved performance of the RHC, cushion adjustment remains as simple as adjusting the cushion needle valve.

Note 1) Strokes shorter than the recommended minimum stroke (1 to 249 st) can be manufactured, but
cushion capability may not be satisfied since the effective cushion stroke for this cylinder is long.
Note 2) Stroke exceeding the standard stroke length is not subject to the guarantee.
