About the Airtac MGD Double Rod Mini Cylinder MGD40X175S
The AirTAC MGD40X175S is a double acting, double rod JIS mini cylinder with a 40 mm bore and 175 mm stroke: a 16 mm rod exits both the front and back covers with an M14x1.5 male thread at each end, so the two rod ends move together and the output force is equal in both directions. Because the rod-side area is active on both sides of the piston, this model delivers about 527.8 N (roughly 53.8 kgf) each way at 0.5 MPa and 738.9 N at 0.7 MPa, with a theoretical maximum of 107.6 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. For a realistic vertical lift, halve the push figure: plan on about 27 kg.
Construction follows the JIS round-body mini format: a SUS304 stainless barrel with hard-chrome plated carbon-steel rods, riveted covers, and a two-way lubricant-storing piston seal, suited to damp and washdown environments. Fixed anti-impact bumper pads decelerate the stroke ends; they are not an adjustable air cushion. The fitted magnet (the S code) allows CMSG, DMSG or EMSG switches to be mounted on either rod side. Ports are 1/8" on every MGD bore, 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 fluid is air filtered to 40 um.

Where the Airtac MGD Double Rod Mini Cylinder MGD40X175S Is Used
Anti-rotation slide
The through-rod keeps the tool plate from rotating on a 175 mm push-pull slide, with 527.8 N available in each direction for clamping or ejecting in a 40 mm-bore station.
Twin-load push
Drive two small chutes or diverters at once, one load on each rod end, using the equal 527.8 N output both ways at 0.5 MPa for balanced transfer motion.
Rear-mounted switch flag
The magnet and rear rod end carry a stop or position flag read by CMSG/DMSG/EMSG switches, giving repeatable stroke-end signalling on packaging or assembly machinery.
Is the Airtac MGD Double Rod Mini Cylinder MGD40X175S the Right Cylinder?
At 40 mm bore this is the largest MGD, with 527.8 N each way at 0.5 MPa; the smaller MGD bores (20, 25, 32) give 131.9, 206.1 and 345.6 N respectively at the same pressure, so step down if your load is lighter. If you need a 50 or 63 mm bore or an adjustable cushion, move to the MGCD series; for a single-rod cylinder, the MG series is the equivalent. Choose the MGD40X175S when you need anti-rotation guidance, equal force in both directions, a rear rod end for a switch flag or a second load, or symmetric transfer motion. Mounting is FA flange or LB foot, with I and Y rod knuckles available (no SDB or CB pivots on the double-rod design); the fitted magnet supports CMSG/DMSG/EMSG position sensing. The 175 mm stroke is within the 500 mm maximum standard stroke for this bore. On long strokes, keep side load on the rod low and support the work, since the through-rod resists but does not eliminate side-load wear. Note that the cylinder does not hold position on air loss; for a held load, add 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 MGD40X175S FAQ
Force is equal in both directions because the rod-side area works both ways: 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa, with a theoretical maximum of 107.6 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, port 1/8", rod 16 mm with M14x1.5 threads at both ends, and the maximum standard stroke for this bore is 500 mm.
The MGD has a rod exiting both covers, so force is identical extending and retracting, the rod resists rotation and side load, and the rear end can carry a flag or a second load; the single-rod MG has a larger push than pull and no rear rod. This S-coded model has a magnet fitted, so CMSG, DMSG or EMSG switches can be mounted. The bumper pads only soften the stroke ends; they are not an adjustable cushion, and the cylinder will not hold a load on air loss.
