The AirTAC Airtac MGD Double Rod Mini Cylinder MGD32X350 is a genuine double acting, double rod JIS-standard round-body mini air cylinder with a Ø32mm bore and 350mm stroke, 1/8" air ports and a SUS304 stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.
The AirTAC MGD32X350 is a JIS-standard round-body mini cylinder that is double acting with a double rod: a 12 mm hard-chrome rod exits both the front and rear covers with the same M10x1.25 male thread at each end. Because the rod-side piston area is pressurized in both directions, the output force is equal either way, 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, and the free rear rod end can carry a stop or switch flag or drive a second load in perfect sync.
Built around a SUS304 stainless barrel with riveted covers and a fixed anti-impact bumper pad at each stroke end, this 350 mm stroke cylinder suits damp and washdown-prone lines. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), withstands 1.5 MPa (215 psi) proof pressure, and covers -20 to +70 C at 30-800 mm/s. As a realistic working figure, halve the 345.6 N push: about 17 kg is a safe vertical load. Note that the piston drifts on air loss, so use an external rod lock or pilot check valve to hold position, and add the optional S magnet code if you later need CMSG, DMSG or EMSG sensing.

MG-family variants: MG / MGC (double acting ±cushion), MSG / MTG (single acting push / pull), MGD / MGCD (double rod ±cushion). Accessories: LB foot, FA flange, plus I and Y knuckles. Thread PT (blank) / G / NPT.
Both rod ends drive two slides or clamps at once with identical 345.6 N force each way at 0.5 MPa, keeping the two stations perfectly matched through the full 350 mm stroke.
The through-rod resists rotation and side load, guiding parts in a straight line on conveyor or assembly tooling without extra guide hardware.
The free back rod carries a mechanical stop or position flag; with the optional S magnet, a CMSG or DMSG switch reports stroke-end position.
At 32 mm bore the MGD32X350 is the second-largest in the MGD range, delivering 345.6 N each way at 0.5 MPa. Step down to MGD25 for lighter symmetric pushes or up to MGD40 for 527.8 N; if you need a bore of 50 or 63 mm or an adjustable air cushion, move to the MGCD, and for a conventional single-rod cylinder choose the MG. The 350 mm stroke sits within the 500 mm maximum standard stroke for this bore. Choose the through-rod format when anti-rotation guidance, dual synchronized loads or a rear-mounted stop flag matter. Mount with the FA flange or LB foot (no SDB/CB pivot options here) and pair with I or Y rod knuckles. The thread is PT; order the S suffix for magnet and CMSG/DMSG/EMSG switch capability. On long strokes like this one, keep side load on the rod low and support the workpiece to protect the bearings.
Quick checklist
It is double acting with a double rod, so force is equal both ways: 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, and speed 30-800 mm/s. The port is 1/8" and the rod thread is M10x1.25 at both ends.
The MGD32X350 has a rod exiting both covers, giving equal force in extend and retract, inherent anti-rotation, and a usable rear rod end for a stop flag or second load; the MG has one rod and a larger extend force. The fixed bumper pads soften stroke ends but are not an adjustable cushion (that is the MGCD). Add the S magnet code to fit CMSG, DMSG or EMSG sensors, and remember the piston drifts on air loss, so hold loads with an external rod lock or check valve.
