About the Airtac MGD Double Rod Mini Cylinder MGD25X350
The AirTAC MGD25X350 is a JIS-standard round-body mini cylinder, double acting and double rod: a 10 mm hard-chrome steel rod exits both the front and back covers with the same M10x1.25 male thread at each end. Because the rod-side area is pressurized on both strokes, output is equal in extend and retract, about 206.1 N each way at 0.5 MPa (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, keeps stroke-end position repeatable, and lets the rear rod end carry a stop flag or drive a second load.
Built for damp and washdown environments, the 25 mm bore barrel is SUS304 stainless with riveted covers and a two-way lubricant-storing piston seal, while fixed anti-impact bumper pads decelerate the stroke ends. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof tested to 1.5 MPa (215 psi), from -20 to +70 C at 30-800 mm/s, with a 1/8" port and PT thread. As a rule of thumb, size the working load at about 0.6 of the push force, so roughly 12 kg is a safe vertical figure for this cylinder. The 350 mm stroke exceeds the 300 mm standard maximum for this bore, so it is a made-to-order stroke.

Where the Airtac MGD Double Rod Mini Cylinder MGD25X350 Is Used
Anti-rotation slide
The through-rod on the MGD25X350 resists rotation and side load, keeping a 350 mm linear slide tracking straight over its full travel without external anti-rotation hardware.
Twin-load push
With 206.1 N available at each rod end at 0.5 MPa, one cylinder can drive two small clamps or ejectors simultaneously with identical force in both directions.
Rear-mounted stop flag
The back rod end carries a stop or index flag on a transfer fixture, giving a repeatable stroke-end reference driven from the same 25 mm bore piston.
Is the Airtac MGD Double Rod Mini Cylinder MGD25X350 the Right Cylinder?
At 206.1 N per direction at 0.5 MPa, the 25 mm bore sits in the middle of the MGD range: step down to bore 20 (131.9 N) for lighter symmetric pushes, or up to bore 32 (345.6 N) or 40 (527.8 N) when the load demands more. If you need bores 50 or 63, or an adjustable variable cushion instead of the fixed bumper pad, move to the MGCD; for a single-rod cylinder, the MG is the equivalent. Choose this model when you need anti-rotation guidance, equal force both ways, or a rear rod end for a switch flag or second load. Mounting is FA flange or LB foot, with I and Y rod knuckles available (no SDB/CB pivot on the double rod). This unit has no magnet, so no CMSG/DMSG/EMSG switch can be fitted; order the S code if position sensing is needed. Note the 350 mm stroke is non-standard for this bore (standard maximum 300 mm) and is made to order, and keep side load on the long 350 mm stroke minimal by guiding the load 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 MGD25X350 FAQ
Because both strokes use 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), temperature range is -20 to +70 C, and speed is 30-800 mm/s on air filtered to 40 um.
A rod exits both covers with the same M10x1.25 thread, so the MGD25X350 resists rotation and side load, delivers equal force extending and retracting, and lets the rear rod end carry a stop flag or a second load. The single-rod MG has a larger extend force but no rear rod. This unit has no magnet, so no CMSG/DMSG/EMSG switch can be mounted; specify the S code for sensing.
