SMC 10-CDQSXB16-15DM-A93S | Clean Room Low Speed Compact Cylinder CQSX Series 16mm Bore 15mm Stroke Double-Acting Anti-Stick-Slip With Auto-Switch

The SMC 10-CDQSXB16-15DM-A93S is a clean room specification low speed compact cylinder from the CQSX series with a 16mm bore and 15mm stroke. Part number decoded: CDQSX = compact cylinder with low speed (anti-stick-slip) capability, B = basic mount, 16 = bore mm, 15 = stroke mm, D = double-acting, M = magnetic piston, A93S = pre-mounted auto-switch (solid-state, band mount type). The CQSX series is specifically engineered to eliminate stick-slip — the jerky, unpredictable motion that standard cylinders exhibit at low operating speeds.

What causes stick-slip and why does the CQSX solve it? Standard cylinder seals create a static-to-dynamic friction transition that causes the piston to alternate between sticking and jumping at low speeds. The CQSX uses specially designed low-friction seals and internal surface treatments to maintain smooth, uniform velocity throughout the entire stroke, even at speeds below 50mm/s. This smooth motion reduces vibration-induced particle generation in sensitive clean environments. The pre-mounted A93S auto-switch saves installation time and ensures correct placement, while the 16mm bore compact profile suits gentle workpiece contact and slow-approach mechanisms.

The CDQSXB16-15DM provides low-speed capability in a 16mm compact cylinder with a CQ2-compatible footprint for easy retrofit into existing equipment. For standard speed at 16mm bore, the CDQ2B16 costs less when anti-stick-slip is unnecessary. For larger bore with anti-stick-slip, see CDQSXB20 (20mm) or CDQSXB25 (25mm) variants. For the same CQSX low-speed capability with longer stroke, see CDQSXB16-30DM or CDQSXB16-50DM variants. Clean series (10-) with fluorine grease, particle generation grade 1. RoHS compliant.
