About the Airtac MGD Double Rod Mini Cylinder MGD40X75
The AirTAC MGD40X75 is a double acting, double rod JIS round-body mini cylinder with a 40 mm bore and 75 mm stroke. A 16 mm rod exits both the front and back covers with the same M14x1.5 male thread at each end, so the two rod ends move together and the cylinder pushes with equal force in both directions: about 527.8 N each way at 0.5 MPa and 738.9 N each way at 0.7 MPa, with a theoretical maximum of 107.6 kgf at 1.0 MPa. Because both sides of the piston see the rod-side area, there is no separate push and pull figure, and the through-rod resists rotation and side load while keeping stroke-end position repeatable.
Construction follows the JIS mini-cylinder footprint: a riveted round body in SUS304 stainless with hard-chrome plated rods, suited to damp and washdown surroundings, with 1/8" ports and PT thread. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, air filtered to 40 um, a temperature range of -20 to +70 C, and speeds of 30-800 mm/s. Fixed anti-impact bumper pads decelerate the piston at each stroke end; they are not an adjustable cushion. Mount it with an FA flange or LB foot and add I or Y rod knuckles. For position sensing, order the S code to fit a CMSG, DMSG or EMSG switch. As a rule of thumb, keep vertical loads to about 0.6 of the push force, roughly 32 kg here.

Where the Airtac MGD Double Rod Mini Cylinder MGD40X75 Is Used
Anti-rotation linear slide
The through-rod of the MGD40X75 resists rotation and side load, keeping a 75 mm slide stroke straight and repeatable with 527.8 N of force available in either direction.
Twin-load push station
With the same M14x1.5 thread at both rod ends, one cylinder drives two clamps or pushers at once, each end delivering about 527.8 N at 0.5 MPa.
Rear-mounted stop flag
The back rod end carries a switch or stop flag on a packaging line, giving a position signal at the stroke end while the front end does the work.
Is the Airtac MGD Double Rod Mini Cylinder MGD40X75 the Right Cylinder?
At 40 mm bore the MGD40X75 is the largest cylinder in the MGD range, delivering 527.8 N equally in both directions at 0.5 MPa. Size up to the double-rod MGCD if you need bores of 50 mm or 63 mm or a variable air cushion; choose the single-rod MG if you do not need a through-rod. This model suits anti-rotation slides, twin-load pushing and rear-mounted switch or stop-flag duty, where the back rod end carries a sensor flag or drives a second load. Mount with an FA flange or LB foot and pair with I or Y rod knuckles; SDB and CB pivot mounts are not available on the double-rod design. Add the S code if you plan to fit CMSG, DMSG or EMSG switches. On strokes near or beyond the 500 mm maximum standard stroke for this bore, support the rod to limit side load.

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 MGD40X75 FAQ
It is a double acting, double rod JIS mini cylinder with a 40 mm bore and 75 mm stroke. Force is equal in both directions: 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. Ports are 1/8" with PT thread, the rod is 16 mm with M14x1.5 threads at both ends, operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure is 1.5 MPa (215 psi), and the temperature range is -20 to +70 C at speeds of 30-800 mm/s.
A rod exits both covers of the MGD40X75, so both sides of the piston see the rod-side area and the force is identical extending and retracting; the single-rod MG has a larger push than pull. The through-rod also resists rotation and can carry a stop flag or drive a second load at the rear. To fit CMSG, DMSG or EMSG switches you must order the S code, which adds the piston magnet; without it no sensor can be mounted.
