CDQSB25-20D Applications

This 25 mm bore, 20 mm stroke CQS combines useful force, roughly 245 N at 0.5 MPa, with a very short overall length. It is a practical choice for clamping, pressing, stopping and short lifting motions on assembly and machining fixtures. Auto switches mount flush in the square body for reliable extend and retract confirmation, and the basic through-hole/tapped mounting allows direct bolting to machine plates, making installation straightforward in space-restricted cells.
