Compact cylinders with built-in air cushions provide the possibility of applying pneumatic power into small spaces where, previously, cylinders could not be mounted.

Compact cylinders provide the possibility of applying pneumatic power into small spaces where, previously, cylinders could not be mounted. SMC, the pioneer of compact cylinder design, have now launched a new compact cylinder, designated series RQ, utilising a unique air cushion mechanism. This unique cushion system, designed by SMC's engineers, is located in the same profile as the cylinder itself, with the adjustment screws on the same face as the connections - this eliminates the need for traditional cushion bosses, thereby retaining the compact size of the unit.

The RQ also offers noise reduction at stroke end of 14dB or more, improved repeatability at the stroke end compared to units with rubber bumpers, and up to three time more allowable kinetic energy than standard versions, at the end of stroke which enables heavier weights to be moved, at higher speeds without producing undesirable impacts at the ends of stroke.

In addition, this series is presently offered in bore sizes from 20mm to 50mm, with or without auto switch, and a number of mounting options (through hole, double end tapped, foot, front flange, rear flange and double clevis).
