SMC Corporation NCDGBN20-0050 Pneumatic Cylinder

SMC NCDGBN20-0050 is a compact, double-acting round-body air cylinder from the NCG family that delivers precise linear actuation in a lightweight aluminum, anodized housing. It features a 3/4 in bore and 1/2 in stroke, a magnet-equipped piston for position sensing, and a chrome-plated piston rod with an 8 mm diameter and M8 x 1.25 thread; the rod rotation is a defined feature, enabling versatile end attachments. Mounting options include a male threaded nose for panel mounting and a rear tab with a machined hole for clevis mounting, plus a basic front mounting style for flexible installations. The unit uses a 1/8 in BSPT (Rc) air inlet and operates within an 8 to 145 psi pressure range, with a maximum temperature of 158 °F and a minimum of 14 °F. End caps are aluminum with an anodized finish, and a rubber cushion provides damped travel at the end of stroke. Weighing about 0.1 kg and with a 26 mm body diameter, this RoHS-compliant cylinder is well suited for compact automation tasks where space is at a premium and reliable, repeatable motion is required.
