About the Airtac MGD Double Rod Mini Cylinder MGD32X450S
The AirTAC MGD32X450S is a JIS round-body mini cylinder, double acting, with a through rod that exits both the front and back covers on the same M10x1.25 male thread. Because the rod occupies the piston area on each side, the effective area is the rod-side area in both directions, so the output force is equal each 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 450 mm stroke sits within the 500 mm maximum standard stroke for the 32 mm bore, and the fitted magnet (the S code) allows CMSG, DMSG or EMSG switches to be clamped directly on the SUS304 barrel.
The through-rod is the practical advantage here: it resists piston 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. At a realistic working load, plan on roughly 200 N of usable push, which is about 20 kg horizontally, or a safe vertical figure of around 10 kg. A fixed anti-impact bumper pad decelerates the stroke end on each cover, the 1/8" port is common to every MGD bore, and the hard-chromed carbon-steel rods plus stainless barrel suit damp or washdown environments. Operating range is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure and -20 to +70 C temperature limits.

Where the Airtac MGD Double Rod Mini Cylinder MGD32X450S Is Used
Anti-rotation linear slide
The through rod keeps the piston from rotating, so a 450 mm stroke can index trays or fixtures on a light guide rail without a separate anti-rotation key, with 345.6 N available in each direction.
Twin-load push from one cylinder
Drive a clamp or ejector on the front rod end while the rear rod end carries a second small tool or stop, both moving together with equal 345.6 N force at 0.5 MPa.
Rear-mounted switch or stop flag
With the magnet fitted, the back rod end carries a position flag for CMSG, DMSG or EMSG switches, giving a repeatable stroke-end signal on long transfer strokes.
Is the Airtac MGD Double Rod Mini Cylinder MGD32X450S the Right Cylinder?
Choose the MGD32X450S when you need equal force in both directions over a long 450 mm stroke with anti-rotation guidance from the through rod. At 345.6 N per way at 0.5 MPa it sits above the 20 mm and 25 mm MGD bores (131.9 N and 206.1 N) and below the 40 mm (527.8 N), so size up to MGD40 if your load needs more than about 35 kg of horizontal push at working pressure. If you need a 50 mm or 63 mm bore or an adjustable air cushion, move to the MGCD series; for a conventional single-rod cylinder, the MG series is the equivalent. Mounting is FA flange or LB foot, with I and Y rod knuckles available (no SDB/CB pivot on the double-rod design). The fitted magnet means CMSG, DMSG or EMSG switches can be added without modification. On a 450 mm stroke, keep side load on the rod low and support the workpiece, since the through rod resists rotation but long strokes amplify misalignment.

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 MGD32X450S FAQ
Because the rod exits both covers, 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 1.5 MPa (215 psi), temperature -20 to +70 C, speed 30-800 mm/s, and the air must be filtered to 40 um. The port is 1/8" and the maximum standard stroke for the 32 mm bore is 500 mm.
The MGD has a rod at both ends with the same M10x1.25 thread, so force is identical extending and retracting, rotation is resisted, and the rear rod end can carry a switch flag or a second load; the single-rod MG has a larger push force but unequal pull. The fitted magnet (S code) allows CMSG, DMSG or EMSG switches. Note that the fixed bumper pads only soften the stroke ends: on air loss the piston drifts, so use an external rod lock or pilot check valve to hold a load.
