About the Airtac MGD Double Rod Mini Cylinder MGD25X225
The AirTAC MGD25X225 is a double acting, double rod JIS mini cylinder with a 25 mm bore and 225 mm stroke. A 10 mm rod exits both the front and rear covers with the same M10x1.25 male thread at each end, so the two rod ends move together 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. Because both sides of the piston see the rod-side area, there is no separate push and pull figure, and the through-rod naturally resists rotation and side load.
The barrel is SUS304 stainless with hard-chrome plated rods, and the riveted round-body construction follows the JIS mini footprint. A fixed anti-impact bumper pad softens each stroke end, though it is not an adjustable cushion and will not hold a load on air loss. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, air filtered to 40 um, a speed range of 30-800 mm/s, and a temperature range of -20 to +70 C. This model carries no magnet, so position sensing with CMSG, DMSG or EMSG switches requires the optional S code. At a realistic working load of roughly 0.6 of the force, plan on about 12 kg of thrust per direction at 0.5 MPa.

Where the Airtac MGD Double Rod Mini Cylinder MGD25X225 Is Used
Anti-rotation slide
The through-rod keeps the carriage from twisting on a 225 mm transfer slide, delivering the same 206.1 N in each direction at 0.5 MPa without a separate anti-rotation guide.
Twin-load push
Drive two small fixtures or chutes at once, one load on each M10x1.25 rod end, with balanced 288.5 N force per side at 0.7 MPa keeping both paths synchronized.
Rear-mounted stop flag
Use the back rod end to carry a stop or flag block while the front rod does the work, a classic double-rod arrangement on packaging and assembly stations.
Is the Airtac MGD Double Rod Mini Cylinder MGD25X225 the Right Cylinder?
The MGD25X225 sits in the middle of the MGD range: bore 20 is the smallest, bore 40 the largest at about 527.8 N per direction at 0.5 MPa. If 206.1 N per way is marginal for your load, step up to MGD32; if it is generous, MGD20 saves space. The 225 mm stroke is within the 300 mm maximum standard stroke for bore 25, so no nonstandard build is needed. Choose the MGD when you need anti-rotation, equal force both ways, or a rear rod end for a stop flag or second load; choose the single-rod MG if you only need one rod, or the MGCD if you need an adjustable cushion or a bore of 50 or 63 mm. Mount with the LB foot or FA flange (no CB/SDB pivot mounts on the double-rod), add I or Y rod knuckles as needed, and specify the S code if you want CMSG/DMSG/EMSG switch capability. On long strokes like this 225 mm, support the load to keep side load off the through-rod.

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 MGD25X225 FAQ
Because the rod occupies both sides of the 25 mm piston, 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), the fluid is air filtered to 40 um, speed is 30-800 mm/s, and the temperature range is -20 to +70 C. Ports are 1/8" and the rod thread is M10x1.25 at both ends.
The MGD has a rod exiting both covers, so force is identical extending and retracting, the through-rod resists rotation and side load, and the rear rod end can carry a stop flag or drive a second load. The single-rod MG has a larger push than pull and only one rod end. This MGD25X225 has no magnet fitted, so no sensor can be mounted; order the S version to use CMSG, DMSG or EMSG magnetic switches. Note the cylinder does not hold its load on air loss, so use an external rod lock or pilot check valve where a held position is required.
