SMC Corporation MGQM20-40 Pneumatic Guided Cylinder

SMC MGQM20-40 is a compact 20 mm bore, 40 mm stroke guided cylinder from the MGQ family, engineered for precise, non-rotating linear motion in tight automation spaces where space is at a premium in automation cells and lines. The slide-bearing variant uses internal guide shafts to isolate the load from the rod and seals, delivering stable travel under lateral loads, with rubber bumpers as standard and auto-switch capability for sensor integration and easy control. The MGQ/MGQM lineup covers bores from 12 to 100 mm, and the MGQM20-40 is available with a high-temperature XB6 option for environments up to 150°C (302°F), with bottom-mount configurations commonly used. Typical applications include stop and lift operations on conveyors and pick-and-place or positioning tasks in compact lines where repeatable guided motion is essential; MGQM’s non-rotating accuracy ranges from approximately ±0.08° for the smallest bores to ±0.04° for the largest bores, reflecting improved angular stability with larger diameters.
