About the Airtac MGD Double Rod Mini Cylinder MGD25X200S
The AirTAC MGD25X200S is a double acting, double-rod JIS round-body mini cylinder with a 25 mm bore and 200 mm stroke. 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 and the effective area is the rod-side area on both sides. That means the output force is equal in both directions: about 206.1 N each way at 0.5 MPa, rising to 288.5 N at 0.7 MPa, with a theoretical maximum of 42 kgf at 1.0 MPa. As a rule of thumb, plan on roughly 12 kg as a safe vertical working load at 0.5 MPa.
The through-rod resists rotation and side load, keeps stroke-end position repeatable, and lets the back rod end carry a switch flag or drive a second load while the front rod does the work. The barrel is SUS304 stainless with hard-chrome-plated rods, and the riveted covers carry fixed anti-impact bumper pads that soften the stroke ends (this is a bumper, not an adjustable cushion). The fitted magnet, shown by the S in the model code, accepts CMSG, DMSG or EMSG switches. Ports are 1/8" PT, operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, temperature range is -20 to +70 C, and speed is 30-800 mm/s.

Where the Airtac MGD Double Rod Mini Cylinder MGD25X200S Is Used
Anti-rotation pusher slide
The through-rod on the MGD25X200S resists rotation, keeping a 200 mm pusher or gate plate square to the workpiece through the whole stroke with about 206 N of force in each direction at 0.5 MPa.
Twin-load transfer
With a rod exiting both covers, the front end can push one tray while the rear M10x1.25 thread drives a second gripper or clamp, both moving together with equal 206.1 N force at 0.5 MPa.
Rear-mounted switch flag
The fitted magnet and rear rod end let you carry a CMSG, DMSG or EMSG switch flag on the back of the cylinder, giving end-of-stroke signals on a conveyor stop or sorting station.
Is the Airtac MGD Double Rod Mini Cylinder MGD25X200S the Right Cylinder?
At 25 mm bore the MGD25X200S delivers 206.1 N in each direction, so size up to the MGD32 or MGD40 (345.6 N and 527.8 N at 0.5 MPa) if your load needs more, or down to the MGD20 (131.9 N) for lighter duty. The 200 mm stroke sits inside the 300 mm maximum standard stroke for this bore, so no nonstandard stroke surcharge applies. Choose this model when you need anti-rotation guidance, equal force both ways, a rear rod end for a stop flag or second load, or symmetric transfer. If you need bores of 50 or 63 mm or an adjustable air cushion, step up to the MGCD; for a conventional single-rod cylinder, the MG series is the equivalent. Mounting is FA flange or LB foot, with I and Y rod knuckles available (no SDB/CB pivot on the double-rod). For a 200 mm stroke, support the rod or keep side load low to protect the bearings. The cylinder does 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 MGD25X200S FAQ
Because a rod occupies the piston area on both sides, the force 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), temperature range is -20 to +70 C, speed is 30-800 mm/s, and the air must be filtered to 40 um. Ports are 1/8" PT and the maximum standard stroke for this 25 mm bore is 300 mm.
The MGD25X200S has a rod exiting both covers with the same M10x1.25 thread at each end, so it resists rotation and side load, gives equal force in both directions, and can drive two loads or carry a flag on the rear rod. The single-rod MG has a larger push than pull and no rear rod. The S in the model code means a magnet is fitted, so CMSG, DMSG or EMSG switches can be mounted on the barrel. Note the fixed bumper pads only soften the stroke ends; they are not an adjustable cushion and do not hold a load on air loss.
