About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD63X225S
The AirTAC MGCD63X225S is a double acting, double-rod JIS mini cylinder with a 63 mm bore and 225 mm stroke. A 20 mm rod exits both covers with the same M18x1.5 male thread at each end, so both sides of the piston see the rod-side area and the output force is equal in both directions: about 1400.9 N at 0.5 MPa and 1961.2 N at 0.7 MPa, with a theoretical maximum of 285.7 kgf at 1.0 MPa. A variable air cushion at both ends lets you tune the deceleration at each end of the stroke, so this cylinder can run at higher speeds or carry heavier loads than an un-cushioned body while still stopping smoothly. The rear rod end also gives you a second working surface for a stop, flag or second load.
Construction follows the JIS round-body mini format: a riveted SUS304 stainless barrel with hard-chrome plated rods for long seal and bearing life. 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), operates from -20 to +70 C and covers speeds of 30-800 mm/s. The fitted magnet (the S in the model code) allows CMSG, DMSG or EMSG switches to be mounted directly on the barrel. A practical sizing rule: at 0.5 MPa the 1400.9 N thrust is roughly 142 kgf, so about 85 kg is a safe vertical working load at the usual 0.6 duty factor.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD63X225S Is Used
High-speed anti-rotation transfer
The through-rod resists load rotation while the variable air cushion absorbs the stop at 225 mm of travel, letting this 1400.9 N class cylinder index pallets or fixtures faster than an un-cushioned body.
Twin-load press with soft stop
Rod ends on both covers let the MGCD63X225S press or stake two stations at once with equal 1400.9 N force each way, while the adjustable air cushion gives a smooth, non-jarring end of stroke.
Rear-switch slide with position flag
Mount a CMSG, DMSG or EMSG switch on the magnetised barrel and use the rear rod end to carry a flag or stop, turning this cushioned slide into a monitored, smooth-stopping actuator on a conveyor or gate.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD63X225S the Right Cylinder?
Size the MGCD63X225S when you need the largest force class in the cushioned MG family: 1400.9 N each way at 0.5 MPa, roughly double the 824.3 N of the 50 mm bore. Bores run 20/25/32/40/50/63, with 63 the strongest and standard strokes up to 500 mm, so the 225 mm stroke is a standard length. If you need a double-rod cylinder with a fixed bumper pad instead of an adjustable cushion in bores 20-40, choose the MGD; if a single rod plus cushion is enough, the MGC covers that. The through-rod design suits anti-rotation transfer and twin-sided tooling, and the rear rod end can carry a position flag or a second load. Mount with the FA flange or LB foot (no CB or SDB options on this family) and add I or Y rod knuckles where the load pivots. The fitted magnet supports CMSG/DMSG/EMSG switches for end-of-stroke signalling. For long strokes like this one, keep side loads off the rod or 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 MGCD63X225S FAQ
Because the double rod means both sides of the piston see the rod-side area, force is equal in both directions: 1400.9 N at 0.5 MPa and 1961.2 N at 0.7 MPa, with a theoretical maximum of 285.7 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 range is 30-800 mm/s, and the medium is air filtered to 40 um. Ports are 1/4" and the rod thread is M18x1.5 at both ends.
The cushion at each end is an adjustable air cushion: you tune the needle to control deceleration of the piston as it approaches the cover, which allows higher speeds and heavier loads than a hard stop. It only decelerates the stroke end and is not a lock, so the cylinder will not hold its load on air loss; use an external rod lock or pilot check valve where holding is required. Unlike the MGD, which uses fixed bumper pads, the MGCD has this adjustable cushion; unlike the single-rod MGC, the MGCD has a rod at both ends with equal force in both directions. The fitted magnet (S code) accepts CMSG, DMSG and EMSG switches.
