About the Airtac MGD Double Rod Mini Cylinder MGD25X225S
The AirTAC MGD25X225S is a JIS round-body mini cylinder that is double acting with a double rod: a 10 mm hard-chrome steel rod exits both the front and rear covers with the same M10x1.25 male thread at each end. Because the rod-side piston area is active in both directions, the output force is equal both ways, 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 through-rod resists piston rotation and side load, keeps stroke-end position repeatable, and leaves the rear rod end free to carry a stop or switch flag or drive a second load.
Built for damp and washdown-prone environments, the 25 mm barrel is SUS304 stainless with riveted covers and a two-way lubricant-storing piston seal, while both rods are hard-chrome carbon steel. The fixed anti-impact bumper pad decelerates the stroke end but is not an adjustable cushion and does not hold a load; on air loss the piston drifts, so use an external rod lock or pilot check valve for a held load. The fitted magnet (S code) accepts CMSG, DMSG or EMSG switches, and the 225 mm stroke sits inside the 300 mm maximum standard stroke for this bore. As a computed rule of thumb, take about 0.6 of the push force for realistic working loads, roughly 12 kg of vertical figure on this cylinder.

Where the Airtac MGD Double Rod Mini Cylinder MGD25X225S Is Used
Anti-rotation slide feed
The through-rod on the MGD25X225S resists rotation while pushing a small slide or gripper carrier, with 206.1 N available in each direction at 0.5 MPa for symmetric extend and retract cycles.
Twin-load push
Drive two light fixtures or eject two parts at once, one load on each M10x1.25 rod end, splitting the 288.5 N at 0.7 MPa between both sides of the 25 mm double-rod cylinder.
Rear-mounted switch or stop flag
Use the back rod end of the MGD25X225S to carry a stop block or position flag, with the fitted magnet reporting stroke-end position to CMSG, DMSG or EMSG switches along the 225 mm stroke.
Is the Airtac MGD Double Rod Mini Cylinder MGD25X225S the Right Cylinder?
At 25 mm bore the MGD25X225S delivers 206.1 N each way at 0.5 MPa, so size up to the 32 mm (345.6 N) or 40 mm (527.8 N) MGD if your load needs more, or down to the 20 mm (131.9 N) if it needs less. For bores of 50 or 63 mm, or if you need an adjustable variable cushion instead of the fixed bumper pad, choose the double-rod MGCD; for a conventional single-rod cylinder, the MG series. This through-rod model suits anti-rotation slides, twin-load pushes and rear-mounted switch or stop flags. Mount with the FA flange or LB foot (no SDB or CB pivot on the double-rod), add I or Y rod knuckles at either end, and order the S code, fitted here, if you need CMSG, DMSG or EMSG sensing. On long strokes such as 225 mm, support the load carefully to limit side load on the rods. Ports are 1/8" on every MGD bore; thread is PT, with G or NPT available.

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/impact settings and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MGD Double Rod Mini Cylinder MGD25X225S FAQ
Because the rod-side area works in both directions, output is equal each way: 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 1.5 MPa (215 psi), temperature -20 to +70 C, speed 30-800 mm/s, and the fluid is air filtered to 40 um. Ports are 1/8" and the maximum standard stroke for this 25 mm bore is 300 mm.
The MGD has a rod exiting both covers with the same M10x1.25 thread at each end, so force is identical extending and retracting, the through-rod resists rotation and side load, and the rear end can carry a switch or stop flag or a second load; the single-rod MG has a larger push than pull and no rear rod. The S code on this model fits a magnet for CMSG, DMSG or EMSG switches. Note the fixed bumper pad only softens the stroke end: it is not an adjustable cushion, and the cylinder will not hold a load on air loss, so add an external rod lock or pilot check valve for held loads.
