SMC CD85N2025A (CD85N20-25-A) - Mini Air Cylinder, 20mm Bore, 25mm Stroke

SMC CD85N2025A Mini Air Cylinder — 20 mm bore, 25 mm stroke, rubber bumper, rail-mount auto switch. SMC CD85N20-25-A is a C85 series ISO 6432 mini air cylinder, double acting with a single rod and a built-in magnet (D) for auto switch detection. Bore is 20 mm with a 25 mm stroke, a standard catalogue stroke for the 20 mm bore. Head cover type N is the basic integrated-clevis body. There is no C suffix, so the cylinder is supplied with the standard rubber bumper rather than air cushion, giving an allowable kinetic energy of 0.27 J at this bore. The A suffix is the rail mounting type for the auto switch, as opposed to the B band mounting used on the rest of this family; note that on 20 mm and 25 mm bores the D-M9 series switches cannot be rail mounted. Air is the operating fluid, proof pressure 1.5 MPa, maximum operating pressure 1.0 MPa and minimum operating pressure 0.05 MPa at this bore. Piston speed range is 50 to 1500 mm/s. Ambient and fluid temperature is -20 to 80 C without an auto switch, or -10 to 60 C with an auto switch fitted. No lubrication is required. Port size is G1/8, piston rod diameter is 8 mm and the rod end thread is M8 x 1.25..

CD85N20-25-A Applications

A short 25 mm stroke C85 cylinder for compact clamping, indexing, gating, stopping and part ejection where travel is limited but full 20 mm bore force is needed. The rubber bumper suits the low end-of-stroke energy typical of short strokes. Unlike the band-mounted siblings in this family, the A suffix specifies rail mounting for the auto switch, which allows switches to be slid and locked anywhere along the rail for repeatable, tool-friendly position setting. Note the D-M9 switch series cannot be rail mounted on 20 mm bores.
