SMC CDQ2B50TF25DZ (CDQ2B50TF-25DZ) - Compact Air Cylinder, 50mm Bore, 25mm Stroke
SMC CDQ2B50TF25DZ Compact Air Cylinder — 50mm bore, 25mm stroke, double acting, G (BSPP) 1/4 port, STANDARD BODY / NO RUBBER BUMPER, rod end female thread, built-in magnet. SMC CDQ2B50TF-25DZ 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 is STANDARD, i.e. WITHOUT the rubber bumper fitted to the otherwise identical CDQ2B50TF-25DCZ; allowable kinetic energy is 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. Theoretical output at 0.5 MPa is 982 N extending and 825 N retracting. Piston speed range 50 to 500 mm/s. Non-lube operation.

CDQ2B50TF-25DZ Applications
The standard non-cushioned build is the economical choice for moderate-speed, light-mass duties where stroke-end impact is not a concern: clamping and locating in fixtures, hold-down on indexing tables, short pushers, and gate or shutter actuation. If the application runs fast or moves significant mass, the rubber bumper variant CDQ2B50TF-25DCZ should be specified instead, as it doubles allowable kinetic energy. G (BSPP) ports suit European and Middle East piping standards, and the built-in magnet accepts auto switches on four body faces.
