About the Airtac MGD Double Rod Mini Cylinder MGD25X100S
The AirTAC MGD25X100S is a JIS-standard round-body mini cylinder, double acting and double rod: a 10 mm hard-chrome rod exits both the front and back covers with the same M10x1.25 male thread at each end. Because the rod-side area is active on both sides of the piston, the output force is identical in extend and retract, about 206.1 N each way at 0.5 MPa and 288.5 N at 0.7 MPa. The through-rod resists rotation and side load, keeps stroke-end position repeatable, and leaves the rear rod end free to carry a stop flag or drive a second load.
Built for damp and washdown environments, the 25 mm barrel is SUS304 stainless with riveted covers and a two-way lubricant-storing piston seal, and a fixed anti-impact bumper pad softens each stroke end. The fitted magnet (the S code) accepts CMSG, DMSG or EMSG switches for end-of-stroke signalling. Ports are 1/8" on every MGD bore, operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof rating, speed range 30-800 mm/s and temperature -20 to +70 C. As a sizing rule of thumb, keep the working load near 0.6 of the push force, so about 12 kg at 0.5 MPa, or roughly 10 kg if the load hangs vertically.

|---|---|
| 0.5 MPa | 206 N |

Where the Airtac MGD Double Rod Mini Cylinder MGD25X100S Is Used
Anti-rotation pick slide
The through-rod keeps a 12 kg gripper or tray fixture from twisting during 100 mm transfer moves, with equal 206.1 N force in both directions so extend and retract cycle times match.
Twin-station push
Drive two small ejectors or clamps from the same 25 mm cylinder by threading M10x1.25 tooling onto both rod ends, using the identical 288.5 N at 0.7 MPa on each side.
Rear-mounted stop flag
Use the back rod end to carry a CMSG or DMSG switch flag or mechanical stop, turning one double acting cylinder into a position indicator for indexing fixtures.
Is the Airtac MGD Double Rod Mini Cylinder MGD25X100S the Right Cylinder?
At 206.1 N (about 21 kgf) per direction at 0.5 MPa, the 25 mm bore is the second step in the MGD range: choose the 20 mm bore for lighter symmetric pushes and the 32 mm bore (345.6 N) when you need more equal-force output, or the 40 mm bore (527.8 N) as the largest MGD. If you need bores of 50 or 63 mm, or an adjustable variable air cushion instead of the fixed bumper pad, move to the MGCD double-rod series; for a conventional single-rod cylinder, the MG series is the equivalent. This model suits anti-rotation slides, twin-load pushes and rear-mounted switch or stop-flag duty thanks to the through-rod. Mount with the LB foot or FA flange and add I or Y rod knuckles at the rod ends (SDB and CB pivot mounts are not offered on the double-rod body). The fitted magnet means CMSG, DMSG or EMSG switches can be clipped on directly. The maximum standard stroke for a 25 mm MGD is 300 mm, so 100 mm is comfortably standard; on long strokes, guide the load externally so the through-rod is not asked to carry bending moment, and remember the cylinder will not hold 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 MGD25X100S FAQ
Because both sides of the piston see the rod-side area, output is equal both ways: 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 range is 30-800 mm/s, and the temperature range is -20 to +70 C. The port is 1/8" and the rod thread is M10x1.25 at both ends.
The MGD25X100S has a rod exiting both covers, so force is the same extending and retracting, the rod resists rotation and side load, and the rear end can carry a stop flag or a second load; the single-rod MG has a larger push than pull and no rear rod. The stroke ends are softened by a fixed anti-impact bumper pad only, not an adjustable cushion. The fitted magnet accepts CMSG, DMSG or EMSG switches, and mounting is LB foot or FA flange with I or Y knuckles.
