SMC's CQS clean room, compact air cylinder has 4 bore sizes. Standard strokes range from 5 to 50mm. 10/11-C(D)QS series, available for clean environment, prevents particle generation in a clean room. 21/22-C(D)QS series offers the same structure as the clean series, and are for the environment in which the use of copper, fluorine and silicon are restricted.

The CQS compact cylinder is available for those small bore cylinder applications where saving space is a concern. The CQS offers standard long strokes * in four bore sizes from 12 to 25mm. Long stroke versions incorporate a wear band and thicker piston to handle the increased bearing needs of the longer strokes. Both switch capable and non-switch capable body styles are the same, and switches
