SMC CDQ2B40TF25DCZ (CDQ2B40TF-25DCZ) - Compact Air Cylinder, 40mm Bore, 25mm Stroke
SMC CDQ2B40TF25DCZ Compact Air Cylinder — 40 mm bore, 25 mm stroke, G 1/8 (BSPP, TF symbol) port thread, double acting with rubber bumper (C body option). SMC CDQ2B40TF-25DCZ is a CQ2-Z series compact air cylinder with a 40 mm bore and a 25 mm stroke. The B mounting symbol denotes the through-hole / head-end-tapped body, and the D prefix indicates a built-in auto switch magnet, so D-M9 series solid state and reed auto switches can be fitted in any of the four auto switch mounting grooves (Z). The TF port thread symbol specifies G (BSPP) threads, G 1/8 at this bore. The C body option adds a rubber bumper at both ends, raising allowable kinetic energy for the 40 mm bore from 0.26 J to 0.52 J. The cylinder is double acting, single rod, with a rod end female thread (M8 x 1.25). Proof pressure is 1.5 MPa, maximum operating pressure 1.0 MPa, piston speed 50 to 500 mm/s, non-lube. Theoretical output at 0.5 MPa is 628 N extending and 528 N retracting. Basic mass is 348 g.

CDQ2B40TF-25DCZ Applications
Specified where end-of-stroke impact must be cushioned: higher cycle rates, heavier tooling, or vertical loads that would otherwise hammer the end covers. The rubber bumper doubles allowable kinetic energy and reduces noise and shock into the machine frame. Typical duties are conveyor stoppers and diverters, clamping and lifting in jigs, indexing pushers and pick-and-place tooling. G (BSPP) ports suit European and Middle East piping, and the built-in magnet allows D-M9 auto switches for end-position confirmation.
