About the Airtac MGD Double Rod Mini Cylinder MGD20X350
The AirTAC MGD20X350 is a JIS round-body mini cylinder, double acting, with a through piston rod that exits both the front and rear covers. Because the rod occupies the piston area on each side, the effective area is the rod-side area in both directions, so the cylinder delivers an equal 131.9 N at 0.5 MPa (184.7 N at 0.7 MPa) whether extending or retracting. The 350 mm stroke is a made-to-order length that exceeds the 300 mm maximum standard stroke for a 20 mm bore MGD, so it is quoted as a non-standard build. Ports are 1/8" at both ends and the M8x1.25 male rod thread is identical on each rod end.
The through rod is the working advantage here: it resists piston rotation and side load, keeps stroke-end position repeatable, and leaves the rear rod end free to carry a stop or switch flag or to drive a second load in sync with the front end. Construction is a SUS304 stainless barrel with hard-chrome plated rods and riveted covers, suited to damp and washdown surroundings, and a fixed anti-impact bumper pad softens each stroke end. At a realistic working load, plan on roughly 13 kg of vertical capacity (about 0.6 of the 131.9 N force at 0.5 MPa). Note that the cylinder does not hold its load if air is lost; use an external rod lock or pilot check valve where a held position is required.

Where the Airtac MGD Double Rod Mini Cylinder MGD20X350 Is Used
Anti-rotation light slide
The through rod keeps the carriage from rotating on a 350 mm transfer slide, moving small fixtures or sensors at up to 131.9 N in each direction with repeatable stroke-end positioning.
Twin-load push
Front and rear rod ends each deliver the same 131.9 N at 0.5 MPa, so one cylinder can eject or clamp two small parts simultaneously on a light assembly or packaging station.
Rear-mounted stop flag
With the S code magnet fitted, the back rod end carries a CMSG or DMSG switch flag, giving end-of-stroke confirmation on a long-stroke gate or diverter without extra hardware.
Is the Airtac MGD Double Rod Mini Cylinder MGD20X350 the Right Cylinder?
At 131.9 N per direction at 0.5 MPa, the 20 mm bore is the smallest MGD and suits light slides, gates and twin-load pushes; step up to MGD25 for about 206 N or MGD32 for about 346 N each way. If you need a 50 mm or 63 mm bore, or an adjustable variable cushion instead of the fixed bumper pad, choose the MGCD double-rod series; for a single-rod cylinder, use the MG. The 350 mm stroke is non-standard for this bore (standard tops out at 300 mm), so order it as a made-to-order length and expect a lead time. Add the S code if you want position sensing with CMSG, DMSG or EMSG switches; without the magnet no sensor can be fitted. Mount with FA flange or LB foot and add I or Y rod knuckles at the working end. On this long 350 mm stroke, support the rod and avoid side loading to protect the bearings.

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 MGD20X350 FAQ
It is double acting with a double rod, so force is equal both ways: 131.9 N at 0.5 MPa and 184.7 N at 0.7 MPa, with a theoretical maximum of 26.9 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), temperature range -20 to +70 C, speed 30-800 mm/s, and the fluid is air filtered to 40 um. Ports are 1/8" and the 350 mm stroke is a non-standard length for this 20 mm bore.
The MGD has a rod exiting both covers with the same M8x1.25 thread at each end, giving equal force in both directions, better resistance to rotation and side load, and a free rear rod end for a stop flag or second load. The single-rod MG has a larger extend force than retract force. For sensing, order the S code magnet so a CMSG, DMSG or EMSG switch can be mounted; without the magnet no sensor can be fitted. The fixed bumper pad only softens stroke ends and does not hold a load.
