SMC MGQM20TN-40 Pneumatic Compact Guide Cylinder

SMC MGQM20TN-40 is a compact, double-acting pneumatic guide cylinder with a 20 mm bore and a 40 mm stroke, engineered for precise, non-rotating motion in tight spaces. It employs a slide-bearing guide for anti-lateral load resistance and stable guidance, a hallmark of the MGQ/MGQM family, and includes end cushions (rubber bumpers) on both ends to dampen impact at full extension and retraction. Rated for up to 1.0 MPa (145 psi) maximum operating pressure with a 1.5 MPa proof pressure and a minimum operating pressure of 0.1 MPa for bore sizes in the 20–100 mm range, the cylinder is designed for -10 to 60°C ambient conditions and uses a non-lubricated construction to reduce maintenance in automated lines. Typical applications include serving as stoppers or lifters on conveyor systems, as well as integration into pick-and-place, packaging, and automated assembly tasks where a compact form factor and repeatable stroke are essential. The MGQM20TN-40 variant belongs to SMC’s compact guide cylinder lineup, enabling straightforward mounting of standard accessories and sensors on accessible surfaces to enhance functionality in compact automation layouts.
