About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X150S
The AirTAC MGCD50X150S is a double acting, double-rod JIS mini cylinder with a 50 mm bore and 150 mm stroke. A 20 mm hard-chrome-plated rod exits both covers with the same M18x1.5 male thread at each end, and because both chambers see the rod-side area the output is equal in both directions: about 824.3 N at 0.5 MPa and 1154 N at 0.7 MPa, with a theoretical maximum of 168.1 kgf at 1.0 MPa. A variable air cushion at each end decelerates the piston smoothly, so this cylinder handles higher speeds and heavier loads without hard metal-to-metal stops.
The round-body barrel is riveted SUS304 stainless steel, and the 150 mm stroke keeps the cylinder inside the 500 mm maximum standard stroke for this bore. Air supply is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, operating from -20 to +70 C at 30-800 mm/s on air filtered to 40 um. As a practical sizing rule, plan on roughly 50 kg as a safe vertical working load at 0.5 MPa. The fitted magnet (S code) allows CMSG, DMSG or EMSG switches, and the rear rod end can carry a stop, flag or a second load.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X150S Is Used
High-speed anti-rotation transfer
The through-rod keeps the load from rotating while the variable air cushion at each end lets the 50 mm bore shuttle parts at speed with smooth, adjustable deceleration at both ends of the 150 mm stroke.
Twin-load press with soft stop
Rod ends on both covers each deliver about 824.3 N at 0.5 MPa, so the MGCD50X150S can press or stake two light loads in one cycle, with the air cushion giving a controlled soft landing instead of a jarring stop.
Position-flagged slide with rear switching
The fitted magnet supports CMSG/DMSG/EMSG switches, and the rear rod end carries a stop or flag, making this cylinder a compact cushioned slide for indexing fixtures and end-of-stroke signalling.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X150S the Right Cylinder?
Size the MGCD50X150S when your application needs equal force in both directions plus cushioned, high-speed stops: at 0.5 MPa it delivers 824.3 N each way, so keep the working load near 0.6 of that figure. If you need more force, step up to bore 63 (1400.9 N each way); for lighter duty, bore 40 gives 527.8 N. If you want a double-rod cylinder with a fixed bumper instead of an adjustable cushion in the smaller bores, look at the MGD (20-40 only); for a single-rod cushioned cylinder, the MGC is the equivalent. The through-rod also gives natural anti-rotation and a rear rod end for a stop, flag or second load. Mount with the FA flange or LB foot, add I or Y rod knuckles for linkage, and note that the -S magnet on this model enables CMSG/DMSG/EMSG position sensing. For strokes beyond 150 mm, this bore accepts standard strokes up to 500 mm; keep side loads off the rod on long strokes and guide the load externally.

Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check On first run, back off the cushion and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X150S FAQ
This 50 mm bore, 150 mm stroke double-rod cylinder produces 824.3 N in each direction at 0.5 MPa and 1154 N at 0.7 MPa, with a theoretical maximum of 168.1 kgf at 1.0 MPa. It runs double acting on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), withstands a 1.5 MPa (215 psi) proof pressure, operates from -20 to +70 C, and moves at 30-800 mm/s. Ports are 1/4" and the rod thread is M18x1.5 at both ends.
The MGCD50X150S has an adjustable air cushion at both ends that decelerates the piston near each end of stroke, allowing higher speeds and heavier loads than an un cushioned cylinder. The double rod means force is equal both ways since both sides use the rod-side area. The cushion only slows the piston; it is not a lock, and the cylinder will not hold its position on air loss, so add an external rod lock or pilot check valve for load holding. The fitted magnet (S) enables CMSG/DMSG/EMSG switches. Unlike the MGD, which uses fixed bumper pads, this model has adjustable cushions, and unlike the single-rod MGC it has a rod at both ends.
