About the Airtac MGD Double Rod Mini Cylinder MGD25X75S
The MGD25X75S 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 together over the full stroke. Because the rod-side piston area is active on both sides, 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. Air supply is filtered to 40 um, operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), and the speed range is 30-800 mm/s.
The through-rod is the working advantage here: it resists rotation and side load, keeps stroke-end position repeatable, and leaves the rear rod end free to carry a stop or switch flag or to drive a second load at the same time. The barrel is SUS304 stainless and the rods are hard-chrome plated carbon steel, so the cylinder suits damp and washdown environments. A fixed anti-impact bumper pad softens the stroke ends, and the fitted magnet (the S code) allows CMSG, DMSG or EMSG switches to be mounted directly on the barrel. Ports are 1/8" on this bore. As a realistic working figure, halving the 206.1 N thrust gives roughly 10 kgf each way, so plan loads around 10 kg per direction.

Where the Airtac MGD Double Rod Mini Cylinder MGD25X75S Is Used
Anti-rotation push-pull slide
The through-rod keeps a 10 kg-class slide from rotating while the equal 206.1 N thrust moves it out and back at identical speed and force, ideal for a small transfer or indexing table.
Twin-load clamping
Front and rear rod ends each carry a clamp or pusher, so one 25 mm bore cylinder presses two parts simultaneously with matched force at 0.5 MPa.
Rear-mounted stop or flag
The back rod end drives a stop pin or carries a switch flag for a downstream station, while the magnet and CMSG/DMSG/EMSG switches report end positions on the barrel.
Is the Airtac MGD Double Rod Mini Cylinder MGD25X75S the Right Cylinder?
At 25 mm bore the MGD25X75S delivers 206.1 N in each direction at 0.5 MPa, the same force extending and retracting because both sides work on the rod-side area. If your load needs more, step up to the 32 mm bore (345.6 N each way) or the 40 mm bore (527.8 N each way); if less, the 20 mm bore (131.9 N) is the smallest in the MGD range. Choose the MGD when you need anti-rotation guidance, a rear rod end for a stop flag or a second load, or equal push and pull. For a conventional single-rod cylinder, use the MG; for a double rod with an adjustable air cushion or a 50/63 mm bore, use the MGCD. Mounting is FA flange or LB foot, with I and Y rod knuckles available; note there is no SDB/CB pivot option on the double-rod design. The fitted magnet means CMSG, DMSG and EMSG switches can be added without modification. The maximum standard stroke for this bore is 300 mm, so 75 mm is comfortably standard; on long strokes keep side load on the rod low and support the work if needed. Remember the cylinder will not hold its position on air loss, so fit an external rod lock or pilot check valve for a held load.

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 MGD25X75S FAQ
Output 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, temperature range is -20 to +70 C, and speed is 30-800 mm/s. Ports are 1/8" and the rod thread is M10x1.25 at both ends.
The MGD25X75S has a rod exiting both covers with the same M10x1.25 thread, so force is identical extending and retracting and the through-rod resists rotation and side load; the single-rod MG has a larger extend force but unequal retract force and no rear rod end. The fitted magnet (S code) accepts CMSG, DMSG and EMSG switches. Note the fixed bumper pad only softens the stroke ends; it is not an adjustable cushion, and the cylinder will not hold a load on air loss, so use an external rod lock or pilot check valve for held loads.
