SMC CD85N25300CB (CD85N25-300C-B) - Mini Air Cylinder, 25mm Bore, 300mm Stroke

SMC CD85N25300CB Mini Air Cylinder — 25 mm bore, 300 mm stroke, air cushion, band-mount auto switch type. SMC CD85N25-300C-B is a C85 series ISO 6432 mini air cylinder, double acting, single rod, with a 25 mm bore and 300 mm stroke. The CD85N prefix denotes a built-in magnet (D) for auto switch mounting and an N head cover, the basic type with integrated clevis. The C suffix specifies air cushion in place of the standard rubber bumper, and the B suffix specifies band-type auto switch mounting. 300 mm is the longest listed standard stroke for the 25 mm bore, and it exceeds the 25 mm minimum stroke required for the air-cushion option, so the configuration is valid per the official SMC C85/C75 catalog. Official specifications for the 25 mm bore: fluid air, proof pressure 1.5 MPa, maximum operating pressure 1.0 MPa, minimum operating pressure 0.05 MPa, piston speed 50 to 1500 mm/s, allowable kinetic energy 0.97 J with air cushion, port size G1/8, piston rod diameter 10 mm, rod end thread M10 x 1.25. Non-lube operation. Ambient and fluid temperature -20 to 80 degrees C without auto switch, -10 to 60 degrees C with auto switch. Conforms to ISO 6432 and CETOP RP52P.

CD85N25-300C-B Applications

Long-stroke transfer, lifting and pushing duties benefit from the air cushion, which absorbs the higher end-of-stroke energy that a 300 mm travel builds up. Typical uses include pallet and carton pushers, conveyor diverters, tipping and guard mechanisms and long-reach feeders. Adjustable cushioning reduces shock loading on the clevis mount and end covers, cutting noise and prolonging seal life on high-cycle machines. The built-in magnet supports band-mounted auto switches for end-position feedback to a PLC.
