SMC CDQP2B2020DCM (CDQP2B20-20DCM) - Compact Air Cylinder, 20mm Bore, 20mm Stroke
SMC CDQP2B2020DCM Compact Air Cylinder — 20mm bore, 20mm stroke, axial piping type, double acting single rod, with rubber bumper and rod end male thread (body option CM), built-in magnet, basic mounting. SMC CDQP2B20-20DCM is a CQP2 Series Compact Cylinder, Axial Piping Type, Double Acting, Single Rod, with a 20 mm bore and 20 mm standard stroke. The D prefix denotes a built-in magnet for auto switch mounting, B is the basic mounting style, and the CM body option provides a rubber bumper together with a rod end male thread. The CQP2 shares the CQ2 platform: operating fluid is air, proof pressure 1.5 MPa, maximum operating pressure 1.0 MPa, lubrication not required (non-lube), piston speed 50 to 500 mm/s, and ambient and fluid temperature -10 to 70 degrees C without auto switch or -10 to 60 degrees C with auto switch (no freezing). Port thread type is Rc/M. The axial piping construction routes the ports along the cylinder axis rather than the side, and the compact CQ2-based body allows small auto switches to be mounted without protruding from the body. Supplied without auto switch as standard.

CDQP2B20-20DCM Applications
Use this axial piping compact cylinder where side ports would collide with adjacent tooling or guarding and tubing must exit along the cylinder axis. The 20 mm bore with a short 20 mm stroke suits clamping, indexing, pusher and gate duties on assembly and packaging machines. The rubber bumper absorbs end-of-stroke impact for quieter, longer-lived cycling, while the rod end male thread accepts nuts, knuckle joints and floating couplers. The built-in magnet allows auto switches to confirm rod position without external limit switches.
