SMC MGQM12-40 Guide Cylinder

SMC MGQM12-40 is a compact, double-acting guide cylinder from SMC's MGQ compact guide cylinder family. It features a Ø12 mm bore and a 40 mm stroke, delivering precise linear motion in tight spaces. The MGQM designation identifies a guide model that uses internal guide shafts to support the load independently of the piston rod, helping to maintain alignment and reduce side-load during travel. The MGQM series employs a slide bearing arrangement for the load guide, distinguishing it from MGQL models that use ball bushings. This configuration provides smooth, rigid actuation with a compact form factor, suitable for high-cycle automation tasks. Applications include precision positioning, part transfer, and alignment operations in manufacturing environments where space is at a premium and repeatability matters. As a double-acting cylinder, the MGQM12-40 can extend and retract via air pressure on both sides, enabling rapid cycling and controlled hold. The MGQ family offers a range of bore sizes and strokes, so users can select compatible mounting patterns and mounting accessories alongside the MGQM12-40 to fit existing fixtures or robotic cells.
