SMC CDM2B20300Z (CDM2B20-300Z) - Air Cylinder, 20 mm Bore, 300 mm Stroke

SMC CDM2B20300Z Air Cylinder — 20 mm bore, 300 mm stroke, basic (double-side bossed) mounting, built-in magnet, rubber bumper. SMC CDM2B20-300Z is a CM2-Z series round body air cylinder, double acting, single rod, with a built-in magnet. Decoded per the official SMC CM2-Z how-to-order: CDM2 = air cylinder with built-in magnet (auto switch capable); B = basic mounting style (double-side bossed); 20 = 20 mm bore; 300 = 300 mm stroke, the longest standard stroke listed for the 20 mm bore (25, 50, 75, 100, 125, 150, 200, 250, 300 mm); Z = CM2-Z series suffix. No cushion symbol precedes the Z (A = air cushion), so the cylinder is supplied with the standard rubber bumper; the port thread type is the default Rc and the rod end is the default male thread. Official CM2 specifications: type pneumatic; action double acting, single rod; fluid air; proof pressure 1.5 MPa; maximum operating pressure 1.0 MPa; minimum operating pressure 0.05 MPa; ambient and fluid temperature -10 to 70 C without auto switch (-10 to 60 C with auto switch); lubrication not required (non-lube); piston speed 50 to 750 mm/s; allowable kinetic energy 0.27 J at 20 mm bore with rubber bumper and male thread; stroke length tolerance +1.4/0 mm; port size Rc 1/8; maximum manufacturable stroke 1000 mm at 20 mm bore. SMC notes that long strokes should be verified against the model selection data for rod deflection and buckling.

CDM2B20-300Z Applications

A 300 mm stroke on a 20 mm bore makes this CM2-Z a long-reach, light-force actuator for transfer pushers, gate and shutter opening, extend-retract slides and stacker feeds where the load is modest but the travel is long. The basic double-side bossed body mounts with the supplied nut or optional foot, flange, clevis and trunnion brackets; on long strokes, guide the load externally to keep side loading off the rod. The built-in magnet accepts D-M9 auto switches for end-of-stroke position confirmation.
