About the Airtac MGD Double Rod Mini Cylinder MGD40X100
The MGD40X100 is a double acting, double-rod JIS mini cylinder with a 40 mm bore and 100 mm stroke. A 16 mm rod exits both the front and rear covers with the same M14x1.5 male thread at each end, so the two rod ends move together and the output force is equal in both directions: about 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa, because both chambers work on the rod-side area. The through-rod resists piston rotation and side load, lets the rear rod end carry a stop flag or drive a second load, and keeps stroke-end position repeatable.
Built on a riveted round-body barrel in SUS304 stainless with a hard-chrome steel rod, this 40 mm bore is the largest in the MGD range and suits damp or washdown-prone areas. Fixed anti-impact bumper pads decelerate the stroke ends, and the 1/8" port is common to every MGD bore. Operating range is 0.15-1.0 MPa (22-145 psi) with proof pressure of 1.5 MPa (215 psi), -20 to +70 C, and speeds of 30-800 mm/s. As a rule of thumb, plan on roughly 32 kg as a safe vertical load at 0.5 MPa, about 0.6 of the available force.

Where the Airtac MGD Double Rod Mini Cylinder MGD40X100 Is Used
Anti-rotation pusher slide
The through-rod keeps the piston from rotating, so a 527.8 N push at 0.5 MPa lands square on the part every cycle without external anti-rotation guides.
Twin-load transfer
With equal force at both rod ends, one MGD40X100 can drive two grippers or two part nests in opposite directions at the same 527.8 N each way.
Rear flag position station
The back rod end carries a stop or switch flag, giving a repeatable stroke-end signal on packaging and assembly fixtures; add the S code for CMSG or DMSG switches.
Is the Airtac MGD Double Rod Mini Cylinder MGD40X100 the Right Cylinder?
At 40 mm bore this is the largest MGD, delivering 527.8 N each way at 0.5 MPa; step down to the 32 mm bore (345.6 N) if the load is lighter, or to the 25 mm (206.1 N) for compact duties. If you need bores of 50 or 63 mm or an adjustable cushion instead of the fixed bumper, choose the MGCD; for a conventional single-rod cylinder, the MG is the equivalent. The through-rod is the right pick when rotation must be prevented, when a rear-mounted stop or switch flag is needed, or when one cylinder must drive two loads. Mount with the LB foot or FA flange and add I or Y rod knuckles at the joints (no SDB/CB pivot is offered on the double-rod body). Order the S code if you want position sensing with CMSG, DMSG or EMSG switches; this non-S model carries no magnet, so no sensor can be fitted. Maximum standard stroke for this bore is 500 mm, so 100 mm is comfortably standard; on long strokes keep side load low and guide 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 MGD40X100 FAQ
Because a rod occupies both piston faces, the force is equal in both directions: 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa, with a theoretical maximum of 107.6 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, fluid air filtered to 40 um, and the port is 1/8". Maximum standard stroke for the 40 mm bore is 500 mm.
The rod exits both covers with the same M14x1.5 thread, so you get equal force both ways, built-in resistance to rotation and side load, a rear rod end for a stop flag or second load, and repeatable stroke-end position. The single-rod MG has a larger extend force but a smaller return force and no rear rod. Note the MGD will not hold a load on air loss; use an external rod lock or pilot check valve for held loads, and order the S code if you need CMSG, DMSG or EMSG sensing.
