The SMC 11-CDQSB25-20DM is a clean room specification compact cylinder from the CQS series with guided piston and DM option. Part number decoded: CDQS = CQS series double acting with guide, B = both ends tapped, 25 = 25mm bore, 20 = 20mm stroke, D = option, M = specific modification (typically related to mounting or port arrangement). The CQS dual-guide design prevents rod rotation, providing precise linear motion for clean room automation.
The 25mm bore with 20mm stroke creates a short-travel guided actuator producing approximately 29N at 0.6 MPa with anti-rotation capability. This combination is optimized for precision clamping, short-stroke pressing, and component indexing where the workpiece must be contacted with controlled force and no angular displacement. The dual guide rods share the moment load from offset tooling, extending seal life and maintaining positioning accuracy over millions of cycles.
The CDQSB25-20DM provides guided clamping in the CQS compact form. For the unguided CQ2 at 25mm bore, the CDQ2B25 provides a smaller installation envelope when anti-rotation is not required. For lower speed and smoother motion, the CDQSXB25 (CQSX low speed series) adds velocity damping for stick-slip-free operation. For higher force with guided motion, the CDQSB32 increases bore to 32mm. The CQS accepts D-series auto switches in the Z groove when specified. Clean series (11-) fluorine grease. RoHS compliant.
