About the Airtac MGD Double Rod Mini Cylinder MGD25X25
The AirTAC MGD25X25 is a JIS-standard round-body mini cylinder that is double acting with a double rod: a 10 mm hard-chrome rod exits both the front and rear covers with the same M10x1.25 male thread at each end. Because both chambers work on the rod-side area, the output 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. Air ports are 1/8" on this bore, and the operating range is 0.15 to 1.0 MPa (22 to 145 psi) with a 1.5 MPa (215 psi) proof pressure.
The through-rod resists rotation and side load, keeps stroke-end position repeatable, and lets the rear rod end carry a stop flag or drive a second load while the front end does the work. The SUS304 stainless barrel with hard-chrome rods suits damp and washdown areas, and a fixed anti-impact bumper pad softens each stroke end; it is not an adjustable cushion. With a rule of thumb of about 0.6 of the push force, a safe vertical load is roughly 12 kg. Note that the cylinder does not hold its load on air loss, so use an external rod lock or pilot check valve where a held position matters.

Where the Airtac MGD Double Rod Mini Cylinder MGD25X25 Is Used
Anti-rotation slide
The through-rod keeps a small carrier moving straight on a 25 mm stroke without extra guides, with 206.1 N available in whichever direction the cycle needs.
Twin-load push
Drive two light fixtures or eject two parts at once, one load on each M10x1.25 rod end, with equal 288.5 N at 0.7 MPa on both sides of the cycle.
Rear-mounted stop flag
Use the back rod end to carry a stop or index flag while the front end does the pressing, a classic double-rod duty on compact JIS tooling plates.
Is the Airtac MGD Double Rod Mini Cylinder MGD25X25 the Right Cylinder?
At 25 mm bore the MGD25X25 sits near the small end of the MGD range: it delivers 206.1 N each way at 0.5 MPa, while the 32 mm bore gives 345.6 N and the 40 mm bore 527.8 N, so step up if your load needs more. The 25 mm stroke is well inside the 300 mm maximum standard stroke for this bore. Choose the MGD when you need anti-rotation, equal force both ways, or a rear rod end for a flag or second load; pick the single-rod MG if you only need one rod end, or the MGCD if you need an adjustable cushion or a 50/63 mm bore. Mounting is FA flange or LB foot with I and Y rod knuckles (no SDB/CB pivot). This model has no magnet, so no CMSG/DMSG/EMSG switch can be fitted; order the S code if you need sensing. For long strokes, support the rod to limit side load.

- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting (LB / FA) & knuckle
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 MGD25X25 FAQ
It is double acting with equal output 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 to 1.0 MPa (22 to 145 psi), proof pressure is 1.5 MPa (215 psi), temperature range is -20 to +70 C, speed is 30 to 800 mm/s, the fluid is air filtered to 40 um, and the port is 1/8".
The MGD25X25 has a rod exiting both covers with the same M10x1.25 thread, so force is equal both ways and the rear end can carry a flag or a second load; the single-rod MG has a larger extend force but only one rod end. This model has no magnet, so no CMSG, DMSG or EMSG switch can be mounted; order the S version for sensing. The fixed bumper pad only softens stroke ends, and the cylinder will not hold a load on air loss.
