SMC CDQ2B50TF25DCZ (CDQ2B50TF-25DCZ) - Compact Air Cylinder, 50mm Bore, 25mm Stroke
SMC CDQ2B50TF25DCZ Compact Air Cylinder — 50mm bore, 25mm stroke, double acting, G (BSPP) 1/4 port, WITH RUBBER BUMPER (body option C), rod end female thread, built-in magnet. SMC CDQ2B50TF-25DCZ is a CQ2-Z series compact air cylinder with a 50 mm bore and 25 mm stroke. Double acting, single rod, with a built-in magnet (D) for auto switch position sensing. Through-hole mounting (B) is standard, and the Z designation provides auto switch mounting grooves on 4 surfaces at this bore size. Body option C adds a RUBBER BUMPER, which is the only difference from the otherwise identical CDQ2B50TF-25DZ: the bumper cushions stroke-end impact and raises allowable kinetic energy to 0.91 J versus 0.46 J without cushion. The TF port thread code specifies G (BSPP) threads, port size 1/4. Rod end is the standard female thread, M10 x 1.5. Max. operating pressure 1.0 MPa, min. operating pressure 0.05 MPa, proof pressure 1.5 MPa. Piston speed range 50 to 500 mm/s. Non-lube operation.

CDQ2B50TF-25DCZ Applications
The rubber bumper version is specified where the cylinder runs fast, carries appreciable mass, or cycles continuously and stroke-end impact would otherwise cause noise, shock and premature wear. Typical duties include pushers and ejectors on high-speed packaging lines, part transfer and lifting on assembly machines, and stoppers on conveyors. Allowable kinetic energy doubles compared with the non-cushioned CDQ2B50TF-25DZ. G (BSPP) ports suit European and Middle East piping, and the built-in magnet supports auto switches on four body faces.
