SMC 10-CQ2B32-50DZ | Clean Room Compact Cylinder CQ2 Series 32mm Bore 50mm Stroke Double-Acting Auto-Switch Ready Particle Grade 1

The SMC 10-CQ2B32-50DZ is a clean room specification compact cylinder from the CQ2 series with a 32mm bore and 50mm stroke. Part number decoded: CQ2 = compact square-body cylinder (standard series without air cushion — distinguished from CDQ2 which adds cushioning), B = basic mount, 32 = bore mm, 50 = stroke mm, D = double-acting, Z = auto-switch groove. The 10- clean series prefix ensures fluorine grease, controlled assembly, and anti-static double packaging for particle generation grade 1 environments.

What is the difference between CQ2 and CDQ2? The CQ2B32-50DZ is the standard compact cylinder without built-in air cushioning. The CDQ2 variant (note the extra "D" prefix) adds adjustable air cushioning at one or both ends to absorb end-of-stroke shock. If your application involves high-speed cycling where piston impact generates noise and wear, the CDQ2B32-50DCZ or CDQ2B32-50DCMZ with cushioning may be preferred. The standard CQ2 is the cost-effective choice when operating speeds are moderate and cushioning is unnecessary.

The 32mm bore generates approximately 483N at 0.6 MPa, suitable for workpiece clamping, gate actuation, component positioning, and reject mechanisms in clean room pick-and-place systems. The compact square body reduces mounting height by up to 40% versus round-body cylinders. For shorter strokes, see CQ2B32-25DZ or CQ2B32-30DZ. For longer travel, CQ2B32-75DMZ (75mm) and CQ2B32-100DZ (100mm) extend the range. Compatible with SMC D-series auto switches and AS speed controllers. Clean series (10-) fluorine grease, Particle Grade 1. RoHS compliant.
