About the Airtac MGD Double Rod Mini Cylinder MGD40X450
The AirTAC MGD40X450 is a JIS-standard round-body mini cylinder, double acting, with a through rod that exits both the front and rear covers. Because a rod occupies the piston area on each side, the effective area is the rod-side area in both directions, so output force is equal both ways: about 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. Ports are 1/8" on every MGD bore, and the male rod thread is M14x1.5 at both ends.
The 16 mm hard-chrome-plated rod running through the SUS304 stainless barrel 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 while the front end does the work. Riveted covers and a two-way lubricant-storing piston seal suit damp and washdown surroundings, and a fixed anti-impact bumper pad decelerates each stroke end. 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. At 0.5 MPa the 527.8 N force supports a realistic working load of roughly 32 kgf, or about 16 kg held vertically.

Where the Airtac MGD Double Rod Mini Cylinder MGD40X450 Is Used
Anti-rotation linear slide
The 16 mm through rod resists rotation and side load on a 450 mm stroke, keeping a guided carriage square through 527.8 N of equal force in each direction at 0.5 MPa.
Twin-load push-pull station
Drive two workpieces at once: the front rod end pushes one part while the rear rod end ejects another, with matched 738.9 N at 0.7 MPa available at both ends.
Rear-mounted stop flag
Fit a stop or position flag to the back rod end so stroke-end position is repeatable and visible; add the S code magnet to enable CMSG, DMSG or EMSG switches.
Is the Airtac MGD Double Rod Mini Cylinder MGD40X450 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 MGD32 for lighter duty or up to the MGCD series if you need a 50 mm or 63 mm bore or an adjustable air cushion instead of the fixed bumper pad; choose the single-rod MG when a through rod is not required. The 450 mm stroke sits within the 500 mm maximum standard stroke for this bore, so no nonstandard build is needed. Use the through rod where rotation must be resisted or where the rear rod end can carry a sensor flag or a second load. Mount with the FA flange or LB foot (no SDB/CB pivot on the double rod) and add I or Y rod knuckles at the ends. Order the S code if you want CMSG, DMSG or EMSG switch sensing; this non-S model has no magnet, so no sensor can be fitted. On long strokes like this one, support the side load carefully and note that the cylinder will not hold position on air loss - use 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 MGD40X450 FAQ
Force is equal in both directions because both sides of the piston see the rod-side area: 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 is 1.5 MPa (215 psi), temperature spans -20 to +70 C, speed is 30-800 mm/s, and the fluid is air filtered to 40 um. Ports are 1/8" and the rod thread is M14x1.5 at both ends.
The MGD has a rod exiting both covers with the same M14x1.5 thread at each end, so force is identical both ways, rotation and side load are resisted, and the rear end can carry a flag or drive a second load; the MG has one rod and a larger extend force. The fixed bumper pad only softens the stroke end - it is not an adjustable cushion like the MGCD, and it will not hold a load on air loss. Sensors (CMSG, DMSG, EMSG) require the optional S magnet code; this non-S model has no magnet.
