About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD25X450S
The AirTAC MGCD25X450S is a JIS round-body mini cylinder, double acting, with a double rod and a variable air cushion at both ends. A 10 mm hard-chrome rod exits both covers with the same M10x1.25 male thread each end, so the rod-side area is pressurized whichever way the piston moves and the output force is equal in both directions: about 206.1 N at 0.5 MPa and 288.5 N at 0.7 MPa, with a theoretical maximum of 42 kgf at 1.0 MPa. The adjustable cushion decelerates the piston smoothly at each end of the long 450 mm travel, allowing higher speeds and heavier loads than an uncontrolled stop would permit.
Because the 450 mm stroke exceeds the 300 mm maximum standard stroke for this 25 mm bore, it is supplied as a non-standard, made-to-order length. The SUS304 stainless barrel and riveted covers suit washdown and confined JIS footprints, and the fitted magnet allows CMSG, DMSG or EMSG switches to be mounted along the barrel. As a realistic working figure, the 206.1 N push at 0.5 MPa is roughly 21 kgf, so a safe vertical load is about 10 kg. Note that the cushion only decelerates the stroke ends; it is not a lock, so use an external rod lock or pilot check valve if the load must hold on air loss.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD25X450S Is Used
High-speed anti-rotation transfer
The through-rod resists load rotation while the variable air cushion tames the stop over the long 450 mm travel, letting a 21 kgf-class push run at speed without hard end impacts.
Twin-load press with soft stop
Rod ends on both covers each carry a small pad or fixture, and the adjustable cushion gives a smooth deceleration into the work at roughly 206 N per direction at 0.5 MPa.
Rear-switch slide on a long stroke
The rear rod end drives a position flag past CMSG or DMSG switches while the cushioned ends protect the mechanism across the full 450 mm non-standard stroke.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD25X450S the Right Cylinder?
Size by force, not bore: at this 25 mm size the MGCD25X450S delivers 206.1 N each way at 0.5 MPa, so step up to bore 32 or 40 if your load needs more, or down to bore 20 to save space. If you need a double-rod cylinder with a fixed bumper pad instead of an adjustable cushion in the 20 to 40 range, choose the MGD; if a single rod plus cushion is enough, the MGC is the equivalent single-rod build. This model suits anti-rotation transfer work where the rear rod end can carry a stop flag or a second load, and the variable air cushion is set with the cover adjusters to match your speed and mass. Mount with the LB foot or FA flange and pair with I or Y rod knuckles (SDB and CB are not offered). The fitted magnet means CMSG, DMSG or EMSG switches can be added for end-of-stroke signaling. For the long 450 mm stroke, guide the load externally to keep side loads off the bearings.

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 MGCD25X450S FAQ
Because it is a double-rod cylinder, the force is equal in both directions: 206.1 N at 0.5 MPa and 288.5 N at 0.7 MPa, with a theoretical maximum of 42 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 fluid is air filtered to 40 um. The port is 1/8" and the rod thread is M10x1.25 on both ends.
The MGCD25X450S has an adjustable air cushion at both ends that decelerates the piston near each stroke end, so you can run higher speeds or carry heavier loads without hard stops; it is not a brake and will not hold the load on air loss, so add an external rod lock or pilot check valve for that. Unlike the MGD, which uses fixed bumper pads, the cushion here is adjustable. Unlike the single-rod MGC, this is a double-rod build, so force is equal both ways and the rear rod end can carry a stop flag or second load. The fitted magnet also allows CMSG, DMSG or EMSG switches.
