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.
