SMC CD85N25300B (CD85N25-300-B) - Mini Air Cylinder, 25mm Bore, 300mm Stroke

SMC CD85N25300B Mini Air Cylinder — 25 mm bore, 300 mm stroke, rubber bumper, band-mount auto switch type. SMC CD85N25-300-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. No C suffix is present, so the cylinder uses the standard rubber bumper rather than air cushion, and the B suffix specifies band-type auto switch mounting. 300 mm is the longest listed standard stroke for the 25 mm bore 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 0.4 J with rubber bumper, 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.

CD85N25-300-B Applications

The full 300 mm standard stroke suits long-travel pushing, lifting and transfer duties such as pallet pushers, product diverters, guard and hatch actuation and feeding mechanisms on conveyors. The slim ISO 6432 round body fits confined machine frames where a tie-rod cylinder will not, while the integrated clevis head cover simplifies pivoting mounts. The built-in magnet allows band-mounted auto switches to confirm both end positions for PLC interlocks and cycle sequencing.
