SMC CD85N2075B (CD85N20-75-B) - Mini Air Cylinder, 20 mm bore, 75 mm stroke
SMC CD85N2075B Mini Air Cylinder — 20 mm bore, 75 mm non-standard stroke, rubber bumper (no air cushion), band mounting for auto switch. SMC CD85N20-75-B is a C85 series ISO 6432 mini air cylinder, double acting single rod, basic (N) mounting, with a built-in magnet (D) for auto switch detection. Bore 20 mm, stroke 75 mm (an intermediate stroke; SMC supplies strokes other than the standard 10/25/40/50/80/100/125/160/200/250/300 mm on request), standard rubber bumper cushioning, band mounting (B) for auto switches. Piston rod diameter 8 mm with M8 x 1.25 rod end thread and G 1/8 ports. Fluid: air. Proof pressure 1.5 MPa, maximum operating pressure 1.0 MPa, piston speed 50 to 1500 mm/s. Ambient and fluid temperature -10 to 60 degC for built-in magnet types. Lubrication not required.

CD85N20-75-B Applications
Chosen when machine geometry calls for an intermediate 75 mm travel that falls between SMC's standard C85 strokes, typical of retrofit work, custom jigs, stoppers and pusher arms on packaging and assembly lines. Rubber bumpers cushion the end of stroke at moderate speeds, and the built-in magnet allows band-mounted auto switches to be clamped anywhere along the barrel for accurate end-position feedback without external limit switches.
