SMC CDQ2B2040DCZ (CDQ2B20-40DCZ) - Compact Air Cylinder, 20mm Bore, 40mm Stroke

SMC CDQ2B2040DCZ Compact Air Cylinder — 20mm bore, 40mm stroke, double acting, rubber bumper. SMC CDQ2B20-40DCZ is a CQ2-Z series compact air cylinder with a 20 mm bore and a 40 mm standard stroke. It is double acting, single rod, with a through-hole (B) mounting style and a built-in magnet for auto switch position sensing. The C body option adds a rubber bumper; the rod end retains the standard M5 x 0.8 female thread. The Z suffix denotes the auto switch mounting groove, machined on 2 surfaces on bores 12 to 25 mm. Ports are M5 x 0.8 and the piston rod diameter is 10 mm. Operating medium is air, with a proof pressure of 1.5 MPa, a maximum operating pressure of 1.0 MPa and a minimum operating pressure of 0.05 MPa. Piston speed range is 50 to 500 mm/s, lubrication is not required (non-lube), and the ambient and fluid temperature range is -10 to 60 C with the auto switch magnet fitted. Stroke length tolerance is +1.0 / 0 mm, and with the rubber bumper fitted the allowable kinetic energy rises to 0.110 J versus 0.055 J without cushion. Theoretical output at 0.5 MPa is 157 N extending and 118 N retracting.

CDQ2B20-40DCZ Applications

At 40 mm this is the longest stroke in this group, giving useful travel for pushing, ejecting, lifting and transfer moves while keeping the shallow CQ2 body profile. The rubber bumper absorbs end-of-stroke impact and doubles the allowable kinetic energy to 0.110 J, which matters as stroke and inertia increase. The through-hole mount bolts the cylinder flush through a plate, and the built-in magnet lets auto switches sit in the machined groove for reliable position feedback.
