About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD40X225
The AirTAC MGCD40X225 is a double acting, double-rod JIS-standard round-body mini cylinder with a 40 mm bore and 225 mm stroke. Because a 16 mm rod exits both covers with the same M14x1.5 male thread at each end, both sides of the piston see the rod-side area, so the output force is equal in both directions: about 527.8 N each way at 0.5 MPa and 738.9 N at 0.7 MPa, with a theoretical maximum of 107.6 kgf at 1.0 MPa. A variable air cushion at both ends lets you tune the deceleration for smooth, high-speed stops under heavier loads, and the rear rod end doubles as a mounting point for a stop, flag or second load. As a rule of thumb, keep the working load near 0.6 of the push force, so about 32 kg for this cylinder, or roughly 26 kg if it lifts a vertical load.
Construction follows the JIS mini-cylinder footprint with a riveted round body: a SUS304 stainless barrel paired with a hard-chrome plated carbon-steel rod for low wear and corrosion resistance. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), tolerates a proof pressure of 1.5 MPa (215 psi) and a temperature range of -20 to +70 C, and moves at 30-800 mm/s. Ports are 1/8" with PT thread as standard (G and NPT options), mounting is via FA flange or LB foot with I and Y rod knuckles available, and the 225 mm stroke sits well inside the 500 mm maximum standard stroke for this bore. Add the S option to fit CMSG, DMSG or EMSG switches; without the magnet no sensor can be mounted.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD40X225 Is Used
High-speed anti-rotation transfer
The through-rod keeps the load from twisting while the variable air cushions tame 225 mm of travel at up to 800 mm/s, so parts arrive square at each end of a pick-and-place slide.
Twin-load press with soft stop
Rod ends front and rear each carry a small pad, giving about 527.8 N per face at 0.5 MPa, and the adjustable cushions absorb the impact instead of hammering the fixture.
Rear-switch slide
The rear rod end drives a flag past CMSG or DMSG switches (with the S option) for position confirmation on a conveyor gating or indexing stroke.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD40X225 the Right Cylinder?
Size the MGCD40X225 when your application needs roughly 527.8 N (about 32 kg working load at the 0.6 rule) in BOTH directions with smooth, adjustable deceleration at each end. If you need more force, step up to the MGCD50 or MGCD63; for lighter duty the MGCD32 costs less. If you want a double-rod cylinder with a fixed bumper instead of an adjustable cushion in the 20-40 bore range, look at the MGD; if a single rod with a cushion is enough, choose the MGC. The through-rod gives natural anti-rotation and a rear rod end for a stop, flag or second load. Order the FA flange or LB foot as needed, add I or Y knuckles on the rod ends, and specify the S option if you plan to fit CMSG, DMSG or EMSG switches. At 225 mm stroke the rod is relatively slender for its length, so support side loads externally or use knuckles to keep the rod in pure tension and compression.

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 MGCD40X225 FAQ
Because the rod-side area is effective in both directions, output is equal both ways: 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa, with a theoretical maximum of 107.6 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure is 1.5 MPa (215 psi), temperature range is -20 to +70 C, speed is 30-800 mm/s, and the fluid is air filtered to 40 um. Ports are 1/8" PT.
Each end has an adjustable air cushion that throttles the exhaust near the end of the 225 mm stroke, decelerating the piston smoothly so you can run faster or carry heavier loads without hard impact; it is an adjustable cushion, not a fixed bumper pad. The cushion only slows the piston at the stroke ends, so the MGCD40X225 does not lock or hold its position if air pressure is lost; add an external rod lock or pilot check valve where load holding matters. The optional S magnet enables CMSG, DMSG or EMSG position switches.
