About the Airtac MGD Double Rod Mini Cylinder MGD32X300S
The AirTAC MGD32X300S is a JIS round-body mini cylinder, double acting and double rod: a 12 mm piston 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 as one. Because the rod-side area is active on both sides of the piston, the output force is equal in both directions - about 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. 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 while the front end does the work.
Construction suits damp and washdown surroundings: a SUS304 stainless barrel with hard-chrome plated rods, riveted covers, a two-way lubricant-storing piston seal, and a fixed anti-impact bumper pad at each stroke end that softens deceleration. The S code means a magnet is fitted, so CMSG, DMSG or EMSG switches can be clamped on either rod. Ports are 1/8" on all four covers, operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, speed range 30-800 mm/s, and the 300 mm stroke sits well inside the 500 mm maximum standard stroke for the 32 mm bore. As a rule of thumb, plan on roughly 21 kg as a safe vertical working load at 0.5 MPa (about 0.6 of the push force).

Where the Airtac MGD Double Rod Mini Cylinder MGD32X300S Is Used
Anti-rotation linear slide
The through-rod on the MGD32X300S resists rotation, keeping a 300 mm slide or gripper plate square through the full stroke without external guides.
Twin-load push-pull station
With 345.6 N available at each rod end at 0.5 MPa, one cylinder can drive two workpieces or a clamp-and-eject pair with identical force both ways.
Rear-mounted switch flag
The back rod end carries a stop or sensor flag for CMSG, DMSG or EMSG switches while the front rod does the pushing, giving stroke-end confirmation on packaging and assembly machinery.
Is the Airtac MGD Double Rod Mini Cylinder MGD32X300S the Right Cylinder?
At 345.6 N per direction at 0.5 MPa, the 32 mm bore is the right pick when your working load sits near 20-21 kg (about 0.6 of the force) or up to roughly 34 kg horizontally with margin. Choose the 20 mm or 25 mm MGD if your load is under about 13 kg or 21 kg respectively, and step up to the 40 mm bore (527.8 N at 0.5 MPa) for heavier pushes. If you need bores of 50 mm or 63 mm, or an adjustable variable air cushion instead of the fixed bumper pad, move to the MGCD series; if you do not need a rod at both ends, the single-rod MG is the lighter alternative. The through-rod is the reason to stay here: it resists rotation and side load, delivers equal force both ways, and lets the rear rod end carry a switch flag or a second load. Mounting is FA flange or LB foot, with I and Y rod knuckles available (no SDB or CB pivot on the double-rod design). The S code already fits CMSG, DMSG or EMSG switches. At 300 mm stroke, support the rod or keep side load low to protect the bearings over the long span.

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 MGD32X300S FAQ
The 32 mm double-rod bore produces 345.6 N in each direction 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, speed range is 30-800 mm/s, and temperature range is -20 to +70 C. Ports are 1/8" and the rod thread is M10x1.25 at both ends.
The MGD has a rod exiting both covers, so force is equal both ways and the through-rod resists rotation and side load; the single-rod MG has a larger extend force but a smaller return force and no rear rod. The S code on this model fits CMSG, DMSG or EMSG switches. Note that the fixed bumper pad only softens the stroke ends - the cylinder does not lock its load when air is lost, so use an external rod lock or pilot check valve for held loads.
