About the Airtac MGD Double Rod Mini Cylinder MGD32X300
The AirTAC MGD32X300 is a double acting, double-rod JIS mini cylinder with a 32 mm bore and a 300 mm stroke. A 12 mm 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 cylinder delivers an equal 345.6 N in each direction at 0.5 MPa (483.8 N at 0.7 MPa, with a theoretical maximum of 70.5 kgf at 1.0 MPa). Because both chambers see the rod-side piston area, there is no stronger push stroke and no weaker pull stroke - a real advantage for symmetric transfer slides and twin-load tooling. Ports are 1/8" on every MGD bore, and the 300 mm stroke sits comfortably inside the 500 mm maximum standard stroke for this bore size.
The through-rod construction resists piston rotation and side load, keeps stroke-end position repeatable, and leaves the rear rod end free to carry a stop flag, a position marker, or a second load. The SUS304 stainless barrel with a hard-chrome plated rod suits damp and washdown environments, and the riveted round-body covers keep the compact JIS footprint. A fixed anti-impact bumper pad decelerates the piston at each stroke end; it is not an adjustable air cushion. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, air filtered to 40 um, -20 to +70 C, and speeds of 30-800 mm/s. As a working rule, keep the vertical load to about 21 kg - roughly 0.6 of the 345.6 N force at 0.5 MPa. Note that the piston will drift if air pressure is lost, so use an external rod lock or pilot check valve for a held load.

Where the Airtac MGD Double Rod Mini Cylinder MGD32X300 Is Used
Anti-rotation transfer slide
The through-rod resists rotation and side load, keeping a 300 mm symmetric slide square at both stroke ends with an equal 345.6 N drive each way at 0.5 MPa.
Twin-load push station
The front and rear M10x1.25 rod ends drive two clamps or ejectors at once, each direction delivering the same 483.8 N at 0.7 MPa from the 32 mm bore.
Rear-mounted stop flag
With the S code magnet fitted, the back rod end carries a stop or position flag for CMSG, DMSG or EMSG switches on packaging and assembly tooling.
Is the Airtac MGD Double Rod Mini Cylinder MGD32X300 the Right Cylinder?
At 32 mm bore the MGD32X300 is the second largest in the MGD range: it gives 345.6 N per direction at 0.5 MPa, above the 206.1 N of the 25 mm bore and below the 527.8 N of the 40 mm bore. Size up to MGD40 if your load needs more than about 35 kgf of working force at 0.5 MPa, or down to MGD25 for lighter symmetric slides. The 300 mm stroke is a standard length for this bore (maximum standard 500 mm), so no nonstandard stroke surcharge applies. If you need bore 50 or 63, or an adjustable variable cushion instead of the fixed bumper pad, move to the MGCD series; for a conventional single-rod cylinder, the MG series is the equivalent. This model has no magnet fitted, so no position sensor can be mounted - order the S code version (MGD32X300S) if you want CMSG, DMSG or EMSG switch sensing. Mounting is FA flange or LB foot, with I and Y rod knuckles available for both rod ends; pivot-style SDB and CB mounts are not offered on the double-rod body. For long strokes like this one, support the load to keep side load on the through-rod within limits.

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 MGD32X300 FAQ
Because a rod occupies both piston faces, the force is equal in both directions: 345.6 N at 0.5 MPa and 483.8 N at 0.7 MPa, with a theoretical maximum of 70.5 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure is 1.5 MPa (215 psi), the fluid is air filtered to 40 um, temperature range is -20 to +70 C, and speed is 30-800 mm/s. The port is 1/8" and the rod thread is M10x1.25 at both ends.
The MGD has a rod exiting both covers, so force is identical extending and retracting, the through-rod resists rotation and side load, and the rear rod end can carry a stop flag or drive a second load. The single-rod MG has a larger push than pull force and no rear rod. This model uses fixed anti-impact bumper pads, not an adjustable cushion (that is the MGCD), and without the optional S code magnet no CMSG, DMSG or EMSG sensor can be fitted.
