SMC CD85N2550B (CD85N25-50-B) - Mini Air Cylinder, 25 mm Bore, 50 mm Stroke

SMC CD85N2550B Mini Air Cylinder — 25 mm bore, 50 mm stroke, rubber bumper, band-mount auto switch. 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 50 mm - a standard o25 stroke (standard range: 10, 25, 40, 50, 80, 100, 125, 160, 200, 250, 300 mm). Cushion: rubber bumper (no 'C' air-cushion designator). 'B' = band mounting for auto switches; auto switches and bands are ordered separately. 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 (approx. 350 g at 50 mm stroke).

CD85N25-50-B Applications

A general-purpose short-stroke actuator for clamping, stopping, ejecting and indexing tasks on packaging, assembly and material-handling machinery. The ISO 6432 round body fits standard mini-cylinder brackets, and the integral clevis allows swinging motion. Rubber bumpers absorb end-of-stroke shock at moderate speeds, so no cushion adjustment is needed. The built-in magnet works with band-mounted reed or solid state auto switches to signal extended and retracted positions back to the controller.
