SMC CDQ2A40TF125DCZ (CDQ2A40TF-125DCZ) - Compact Air Cylinder, 40mm Bore, 125mm Stroke
SMC CDQ2A40TF125DCZ Compact Air Cylinder — 40mm bore, 125mm long stroke, both-ends-tapped mount, G (BSPP) port thread, double acting with rubber bumper and standard female rod end (DCZ), built-in magnet. SMC CDQ2A40TF-125DCZ is a CQ2-Z series compact air cylinder with a 40 mm bore and a 125 mm stroke, which sits above the 100 mm standard-stroke limit for this bore and therefore falls in the CQ2 long-stroke range. The CDQ2 prefix denotes a built-in magnet for auto switch mounting; mounting style A is both ends tapped. The TF port-thread symbol specifies G (BSPP parallel) port threads. Body option C adds a rubber bumper; the rod end is the standard female thread. Double acting, single rod. Operating fluid is air, proof pressure 1.5 MPa, maximum operating pressure 1.0 MPa and minimum operating pressure 0.05 MPa. Piston speed range is 50 to 500 mm/s, lubrication is not required (non-lube), and stroke length tolerance is +1.0/0 mm. Ambient and fluid temperature is -10 to 70 C without auto switch and -10 to 60 C with auto switch. Allowable kinetic energy at 40 mm bore is 0.52 J with the rubber bumper fitted.

CDQ2A40TF-125DCZ Applications
Chosen where a longer 125 mm travel is needed but installation depth is still tight, such as pushers, ejectors, lifters and diverter gates on packaging, bottling and assembly lines. The rubber bumper absorbs impact energy at both stroke ends, protecting the cylinder and reducing noise during fast cycling. The standard female rod end thread bolts straight to tooling plates, and G (BSPP) ports match European and Middle East fitting stock.
