About the Airtac MGD Double Rod Mini Cylinder MGD25X100
The AirTAC MGD25X100 is a double acting, double rod JIS round-body mini cylinder with a 25 mm bore and 100 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 travel together and the output force is equal in both directions: about 206.1 N each way 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 stronger push stroke to design around - size the load against the single equal figure.
The through-rod resists rotation and side load, keeps stroke-end position repeatable, and lets the rear rod end carry a stop flag, switch bracket or a second load while the front end does the work. Construction suits damp and washdown areas: a SUS304 stainless barrel, hard-chrome plated carbon-steel rods, riveted covers and a fixed anti-impact bumper pad that decelerates the stroke ends. Ports are 1/8" on this bore, operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, speed range 30-800 mm/s, and working temperature -20 to +70 C. As a rule of thumb, keep vertical loads to about 0.6 of the force, roughly 12 kg here.

Where the Airtac MGD Double Rod Mini Cylinder MGD25X100 Is Used
Anti-rotation pick slide
The through-rod keeps the toolplate from twisting on a 100 mm transfer stroke, with 206.1 N available in each direction so approach and return pace match.
Twin-load pusher
Drive two small chutes or nests at once, one load per rod end, splitting the 206.1 N at 0.5 MPa between them in a packaging or sorting station.
Rear-mounted stop flag
Use the back rod end to carry a stop or switch flag into a fixture while the front end presses, keeping stroke-end position repeatable cycle after cycle.
Is the Airtac MGD Double Rod Mini Cylinder MGD25X100 the Right Cylinder?
At 206.1 N per direction at 0.5 MPa, the MGD25X100 sits in the middle of the MGD range: step down to bore 20 for lighter symmetric pushes, or up to bore 32 or 40 (the largest MGD, 527.8 N at 0.5 MPa) when the load needs more. For bores 50 or 63, or for an adjustable air cushion instead of the fixed bumper pad, choose the MGCD double-rod series; for a conventional single-rod cylinder, the MG series. Choose this double-rod model when you need anti-rotation guidance, equal force both ways, a rear rod end for a stop flag or second load, or a repeatable stroke-end position. Mounting is FA flange or LB foot, with I and Y rod knuckles available (no SDB/CB pivots on the double-rod). Add the S code if you plan to fit CMSG, DMSG or EMSG switches - without the magnet no sensor can be mounted. The 100 mm stroke is well inside the 300 mm maximum standard stroke for this bore; on long strokes keep side load on the through-rod modest and guide external slides separately. Note the cylinder does not hold position on air loss, so use 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 MGD25X100 FAQ
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 1.5 MPa (215 psi), temperature -20 to +70 C, speed 30-800 mm/s, and the air must be filtered to 40 um. Ports are 1/8" and the rod thread is M10x1.25 at both ends.
A rod exits both covers, so both strokes use the rod-side area and the force is the same extending and retracting; the through-rod also resists rotation and side load and can carry a stop flag or a second load at the rear end. The single-rod MG has a larger push than pull and no rear rod. Order the S code to fit CMSG, DMSG or EMSG switches - without the magnet no sensor can be mounted. The fixed bumper pad only softens the stroke ends; it is not an adjustable cushion (that is the MGCD) and it does not hold a load.
