About the Airtac MGD Double Rod Mini Cylinder MGD32X400
The AirTAC MGD32X400 is a double acting, double rod JIS round-body mini cylinder with a 32 mm bore and a 400 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 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. Because both chambers see the rod-side area, there is no separate push and pull figure. The through-rod resists rotation and side load, and the free back rod end can carry a stop flag, a position sensor bracket, or drive a second load.
Construction follows the JIS mini-cylinder footprint: a riveted SUS304 stainless barrel, hard-chrome plated carbon-steel rods, two-way lubricant-storing piston seals, and a fixed anti-impact bumper pad at each stroke end that softens deceleration without any adjustment. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof tested to 1.5 MPa (215 psi), from -20 to +70 C at 30-800 mm/s, with a 1/8" port on every bore. This 400 mm stroke sits within the 500 mm maximum standard stroke for bore 32. As a rule of thumb, plan on about 17 kg as the safe vertical load at 0.5 MPa, roughly half the 35 kgf theoretical thrust.

Where the Airtac MGD Double Rod Mini Cylinder MGD32X400 Is Used
Anti-rotation slide feed
The through-rod of the MGD32X400 resists rotation and side load, keeping a 400 mm slide travel straight on pick-and-place or indexing fixtures without external anti-rotation hardware.
Twin-load pressing
With 345.6 N available at each rod end simultaneously at 0.5 MPa, one cylinder can press or clamp two parts at once in light assembly and forming stations.
Rear-mounted flag or stop
The back rod end drives a stop pin or carries a switch flag, letting the same 32 mm bore cylinder sequence a downstream station or trigger position feedback.
Is the Airtac MGD Double Rod Mini Cylinder MGD32X400 the Right Cylinder?
At 32 mm bore the MGD32X400 delivers 345.6 N each way at 0.5 MPa, the second-largest force in the MGD range: step up to bore 40 (527.8 N) for heavier loads or down to bore 25 (206.1 N) if space matters; bore 20 is the smallest MGD. For bores 50 or 63, or if you need an adjustable variable cushion instead of the fixed bumper pad, choose the MGCD; for a conventional single-rod cylinder, the MG. This model suits anti-rotation slides, symmetric transfer, and twin-load pushing, and the rear rod end keeps stroke-end position repeatable or carries a flag. Mounting is FA flange or LB foot, with I and Y rod knuckles available (no SDB/CB pivot on the double-rod). This SKU has no magnet, so no CMSG/DMSG/EMSG switch can be fitted; order the S code if you need position sensing. At 400 mm stroke, keep side load on the rod 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 MGD32X400 FAQ
Because the rod occupies the piston area on both sides, 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 MGD32X400 has a rod exiting both covers, so force is equal both ways and the rear rod end can carry a stop flag or a second load, while the single-rod MG has a larger extend force than retract force. The fixed bumper pads soften the stroke ends but are not an adjustable cushion (that is the MGCD). This SKU has no magnet, so no CMSG, DMSG or EMSG switch can be mounted; order the S code variant for position sensing. Note the cylinder does not hold its load on air loss, so use an external rod lock or pilot check valve for held loads.
