CDQSB20-30D Applications

This 20 mm bore, 30 mm stroke CQS cylinder is a general-purpose short-stroke actuator for clamping, stopping, lifting and part ejection in compact automation. The square body allows auto switches to sit flush on three or four faces, so end-of-stroke sensing adds no width in crowded fixtures. At 0.5 MPa it produces about 157 N extending, suitable for jig clamping, gate stops and small press or transfer motions on assembly and packaging machinery where axial space is limited.
