SMC CD85N25450BX2018 (CD85N25-450-B-X2018) - Mini Air Cylinder, 25 mm Bore, 450 mm Stroke

SMC CD85N25450BX2018 Mini Air Cylinder — 25 mm bore, 450 mm stroke, rubber bumper, band-mount auto switch, -X2018 long-stroke special order. SMC C85 series ISO 6432 mini air cylinder, double-acting single rod, basic (integral clevis) 'N' mounting with built-in magnet ('D') for auto switch detection. Bore 25 mm, stroke 450 mm. Cushion: rubber bumper (Nil - no air cushion designator). 'B' = band mounting for auto switches; auto switches and bands are ordered separately. The 450 mm stroke exceeds the o25 standard stroke range (10, 25, 40, 50, 80, 100, 125, 160, 200, 250, 300 mm), so SMC supplies it as special order -X2018; maximum manufacturable stroke for o20/o25 is 1000 mm. Official SMC specifications: fluid air; action double-acting, single rod; proof pressure 1.5 MPa; maximum operating pressure 1.0 MPa; piston speed 50 to 1500 mm/s; ambient and fluid temperature -20 to 80 C, restricted to -10 to 60 C because of the built-in magnet; lubrication not required (use turbine oil Class 1 ISO VG32 if lubricated). Bore 25 mm details: piston rod diameter 10 mm, piston rod thread M10 x 1.25, port size G 1/8. Weight: basic 258 g plus 18.4 g per 10 mm of stroke.

CD85N25-450-B-X2018 Applications

Suited to long-travel pneumatic motion where a compact ISO 6432 round-body cylinder is preferred over a bulkier profile actuator. Typical duties include pushing, lifting, clamping and transfer strokes on conveyors, packaging lines and assembly stations. The built-in magnet lets band-mounted auto switches confirm end positions for PLC interlocks. Because the 450 mm stroke is a special-order length, allow for rod buckling and lateral load at full extension, and support the rod end where side loading is possible.
