About the Airtac MGD Double Rod Mini Cylinder MGD25X25S
The AirTAC MGD25X25S is a JIS-standard round-body mini cylinder, double acting and double rod: a 10 mm piston 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 as one. Because the rod-side area is active on both sides of the piston, 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. The through-rod resists rotation and side load, and the rear rod end can carry a stop flag or drive a second load.
Built for damp and washdown environments, the MGD25X25S pairs a SUS304 stainless barrel with hard-chrome plated rods and riveted covers, and a fixed anti-impact bumper pad softens each stroke end. The fitted magnet (S code) allows CMSG, DMSG or EMSG switches to be mounted directly on the barrel. Operating pressure is 0.15-1.0 MPa (22-145 psi) with proof pressure of 1.5 MPa (215 psi), and speed range is 30-800 mm/s. As a rule of thumb, plan on roughly 12 kg as the safe vertical load at 0.5 MPa, since about 0.6 of the push force is a usable working figure.

Where the Airtac MGD Double Rod Mini Cylinder MGD25X25S Is Used
Anti-rotation slide
The through-rod resists rotation and side load, keeping a small linear slide or pick-and-place gantry tracking straight through its 25 mm stroke without external guides.
Twin-load push
With 206.1 N available at each rod end simultaneously at 0.5 MPa, one cylinder can clamp or eject two parts at once on a compact assembly or packaging station.
Rear-mounted switch flag
The back rod end carries a stop or switch flag that mirrors the front position, giving a repeatable stroke-end signal for CMSG, DMSG or EMSG sensors on the magnet-fitted barrel.
Is the Airtac MGD Double Rod Mini Cylinder MGD25X25S the Right Cylinder?
At 25 mm bore the MGD25X25S delivers 206.1 N in both directions at 0.5 MPa, which suits a realistic working load of about 12 kg vertically or roughly 120 N horizontally. Step up to MGD32 for 345.6 N or MGD40 for 527.8 N at the same pressure; step down to MGD20 if 131.9 N is enough. If you need a larger bore (50 or 63 mm) or an adjustable air cushion instead of the fixed bumper, choose the MGCD double-rod series; for a conventional single-rod cylinder, the MG series is the equivalent. The double rod makes this model a natural fit where anti-rotation guidance, dual simultaneous loads, or a rear-mounted switch or stop flag is needed. Mounting options are FA flange and LB foot, with I and Y rod knuckles available; note there is no SDB or CB pivot option on the double-rod design. The S in this model code means the magnet is fitted, so CMSG, DMSG or EMSG switches can be added. The 25 mm stroke is well within the 300 mm maximum standard stroke for this bore; for longer strokes with side load, support the rod externally.

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 MGD25X25S 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), temperature range is -20 to +70 C, speed is 30-800 mm/s, and the air supply should be filtered to 40 um. The port is 1/8" and the maximum standard stroke for this bore is 300 mm.
The MGD25X25S has a rod exiting both covers with the same M10x1.25 thread, so force is identical extending and retracting, rotation and side load are resisted, and the rear rod end can carry a flag or drive a second load. The single-rod MG has a larger push than pull and no rear rod. The fitted magnet (S code) accepts CMSG, DMSG or EMSG switches, and the fixed bumper pad softens stroke ends but does not hold or brake a load; use an external rod lock or pilot check valve for that.
