CDQSB20-50D Applications

At the top of the CQS 20 mm bore standard stroke range, this 50 mm stroke cylinder covers longer pusher, ejector and lift duties without moving to a bulkier tie-rod design. The flat square body keeps overall length short, and flush-mounted auto switches confirm both stroke ends. It is commonly used for product diverting, tray lifting, chute gates and tooling advance on packaging lines, electronics assembly cells and general machine-build applications running on filtered shop air.
