SMC CD85N25400CBX2018 (CD85N25-400C-B-X2018) - Mini Air Cylinder, 25mm Bore, 400mm Stroke

SMC CD85N25400CBX2018 Mini Air Cylinder — 25 mm bore, 400 mm stroke, air cushion, band-mount auto switch type, -X2018 long-stroke special order. SMC CD85N25-400C-B-X2018 is a C85 series ISO 6432 mini air cylinder, double acting, single rod, with a 25 mm bore and 400 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. The -X2018 suffix is the SMC special order designation applied when the stroke exceeds the standard stroke range: the official SMC C85/C75 catalog note *3 states that for exceeding the standard stroke range it will be available as a special order (-X2018). The 25 mm bore has standard strokes to 300 mm and a maximum stroke of 1000 mm, so a 400 mm stroke is valid under -X2018. The 400 mm stroke also exceeds the 25 mm minimum stroke required for the air-cushion option. 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.

CD85N25-400C-B-X2018 Applications

Supplied under the -X2018 long-stroke special order, this cylinder delivers 400 mm of travel from a 25 mm bore ISO 6432 body, well past the 300 mm catalog stroke limit. It suits extended pushers, lifters, tippers and transfer arms on conveyors, palletisers and packaging lines where one actuator must cover a long reach in a slim envelope. Air cushioning is essential at this length to absorb end-of-stroke energy and protect the integrated clevis and end covers. Band-mounted auto switches give PLC position feedback.
