Compact cylinder series 90-CDQS and 91-CDQS are available for those small bore cylinder applications where saving space is a concern. The CQS offers standard long strokes (up to 300mm) in four bore sizes from 12 to 25mm. 90-CDQS is made from materials compatible with secondary battery manufacturing. 91-CDQS includes a "Lub-retainer" and is compatible with low dew point (40°C) applications. 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 can be mounted on three (12-16 bore) and four (20-25 bore) sides.
