SMC CDQ2A40TF125DCMZ (CDQ2A40TF-125DCMZ) - Compact Air Cylinder, 40mm Bore, 125mm Stroke
SMC CDQ2A40TF125DCMZ Compact Air Cylinder — 40mm bore, 125mm long stroke, both-ends-tapped mount, G (BSPP) port thread, double acting with rubber bumper and rod end male thread (DCMZ), built-in magnet. SMC CDQ2A40TF-125DCMZ 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 options C and M add a rubber bumper and a rod end male thread in place of the standard female rod end. 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-125DCMZ Applications
The 125 mm long stroke gives useful travel while keeping the short CQ2 body length, so it suits pushers, ejectors, gate and diverter arms and lift stations where a tie-rod cylinder would be too long. The rubber bumper softens end-of-stroke impact for quieter, longer-lasting operation at speed, and the male rod end thread mates directly with floating joints, knuckle joints and rod clevises. G (BSPP) ports suit European fitting standards.
