About the Airtac MGD Double Rod Mini Cylinder MGD32X400S
The AirTAC MGD32X400S is a JIS-standard round-body mini cylinder, double acting and double rod: a 12 mm hard-chrome rod exits both the front and back covers with the same M10x1.25 male thread at each end, so the two rod ends travel together. Because the rod-side area is active on both sides of the piston, the output force is equal in each direction, 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. Air ports are 1/8" on this bore, and the 400 mm stroke sits within the 500 mm maximum standard stroke for the 32 mm bore.
The through-rod resists rotation and side load, keeps stroke-end position repeatable, and leaves the rear rod end free to carry a switch flag or drive a second load. This S-coded model carries a magnet, so CMSG, DMSG or EMSG switches can be clipped on for end-of-stroke signalling. A fixed anti-impact bumper pad softens each stroke end, though it is not an adjustable cushion and will not hold a load on air loss. The SUS304 stainless barrel with hard-chrome rods suits damp and washdown areas, operating on filtered air at 0.15-1.0 MPa (22-145 psi) and -20 to +70 C at 30-800 mm/s. As a working rule, size the load to about 0.6 of the push force, roughly 21 kgf horizontal, or about 17 kg vertical.

Where the Airtac MGD Double Rod Mini Cylinder MGD32X400S Is Used
Anti-rotation linear slide
The through-rod keeps a 400 mm stroke slide from rotating, driving a symmetric transfer table with equal 345.6 N force in both directions at 0.5 MPa.
Twin-load push station
Front and rear M10x1.25 rod ends each carry a workpiece pusher, so one double acting cylinder indexes two parts per cycle at up to 483.8 N at 0.7 MPa.
Rear-mounted switch flag
The back rod end carries a stop or sensor flag, and the fitted magnet accepts CMSG, DMSG or EMSG switches for repeatable end-of-stroke signalling.
Is the Airtac MGD Double Rod Mini Cylinder MGD32X400S the Right Cylinder?
At 345.6 N per direction at 0.5 MPa, the 32 mm bore is the second-largest MGD; step down to the 25 mm bore for lighter twin-load work or up to the 40 mm bore (527.8 N) when more equal-force output is needed. If you need a 50 or 63 mm bore or an adjustable air cushion, the double-rod MGCD is the right family, while the single-rod MG suits plain push-pull duty. Choose the MGD32X400S when anti-rotation guidance, dual-end loading or a rear-mounted stop or switch flag matters. Mounting is FA flange or LB foot, with I and Y rod knuckles available; no SDB or CB pivots are offered on the double-rod design. The fitted magnet accepts CMSG, DMSG or EMSG switches. On a 400 mm stroke, keep side load low and support the rod if the application allows drift-free holding only with an external rod lock or pilot check valve.

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 MGD32X400S FAQ
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 1.5 MPa (215 psi), temperature -20 to +70 C, speed 30-800 mm/s, on air filtered to 40 um. The port is 1/8" and the maximum standard stroke for this 32 mm bore is 500 mm.
A rod exits both covers with the same M10x1.25 thread, so both directions see the rod-side area and force is identical extending and retracting, with better resistance to rotation and side load. The single-rod MG has a larger extend force but an uneven retract. This S model is magnet-fitted, so CMSG, DMSG or EMSG switches mount directly; the fixed bumper pad only softens stroke ends, so use an external rod lock or pilot check valve to hold a load.
