About the Airtac MGD Double Rod Mini Cylinder MGD25X75
The AirTAC MGD25X75 is a double acting, double-rod JIS mini cylinder with a 25 mm bore and 75 mm stroke: a 10 mm rod exits both the front and back covers with the same M10x1.25 male thread at each end, so the two rod ends move as one. Because the rod-side area is active on both sides of the piston, the output force is equal in each direction, 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 rotation and side load, keeps stroke-end position repeatable, and lets the rear rod end carry a stop flag or drive a second load. A fixed anti-impact bumper pad softens each stroke end; it is not an adjustable air cushion.
Built for damp and washdown-adjacent lines, the MGD25X75 pairs a SUS304 stainless barrel with a hard-chrome plated rod, riveted round-body covers and a two-way lubricant-storing piston seal. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), tolerates 1.5 MPa (215 psi) proof pressure, works from -20 to +70 C, and cycles at 30-800 mm/s. Ports are 1/8" on every MGD bore. Mounting is FA flange or LB foot with I and Y rod knuckles; this non-S version carries no magnet, so no position sensor can be fitted unless you order the S code, which accepts CMSG, DMSG or EMSG switches. For a realistic working load, size around 0.6 of the thrust: roughly 12 kgf horizontal, or about 10 kg vertical.

Where the Airtac MGD Double Rod Mini Cylinder MGD25X75 Is Used
Anti-rotation slide
The through-rod keeps a 10-12 kg pallet or fixture plate travelling straight on a 75 mm transfer stroke without a separate guide, with equal 206.1 N thrust in both directions.
Twin-load push
Front and rear rod ends each drive a small clamp or ejector at the same 206.1 N at 0.5 MPa, halving the cylinder count on compact 25 mm bore assemblies.
Rear-mounted stop flag
With the S code, the back rod end carries a flag for CMSG or DMSG switches, giving repeatable end-of-stroke signalling on a packaging or assembly station.
Is the Airtac MGD Double Rod Mini Cylinder MGD25X75 the Right Cylinder?
At 25 mm bore the MGD25X75 delivers 206.1 N each way at 0.5 MPa, so plan on about 12 kgf of usable horizontal thrust or roughly 10 kg vertical. Step down to the 20 mm MGD if your load is light and space is tight, or up to the 32 mm (345.6 N) or 40 mm (527.8 N) MGD for heavier duty. If you need a 50 or 63 mm bore or an adjustable cushion, move to the MGCD; for a single-rod cylinder, the MG is the equivalent. The double rod is the reason to pick this model: it resists rotation and side load, gives identical force extending and retracting, and lets the rear rod end carry a stop flag, a sensor flag bracket or a second load. Choose the S code if you want CMSG, DMSG or EMSG position sensing; this non-S unit has no magnet and accepts no sensor. FA flange or LB foot mounting plus I and Y knuckles cover most fixings, and the 75 mm stroke sits well inside the 300 mm maximum standard stroke for this bore. On long strokes, guide the load externally rather than letting the rod take lateral force.

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 MGD25X75 FAQ
The 25 mm double-rod bore gives 206.1 N at 0.5 MPa and 288.5 N at 0.7 MPa, equal in both directions, with a theoretical maximum of 42 kgf at 1.0 MPa. It runs on 40 um filtered air at 0.15-1.0 MPa (22-145 psi), withstands 1.5 MPa (215 psi) proof pressure, operates from -20 to +70 C at 30-800 mm/s, and has a 1/8" port. The 75 mm stroke is within the 300 mm maximum standard stroke for this bore.
A rod occupies the piston area on both sides, so the MGD25X75 pushes and pulls with the same force and naturally resists rotation and side load, while the rear rod end can carry a stop flag or a second load; the single-rod MG has a larger extend force but no through-rod. The fixed bumper pad only softens stroke ends, so the load will drift on air loss and needs an external rod lock or pilot check valve to hold position. This non-S version has no magnet; order the S code to fit CMSG, DMSG or EMSG switches.
