About the Airtac MGD Double Rod Mini Cylinder MGD40X175
The AirTAC MGD40X175 is a JIS-standard round-body mini cylinder, double acting and double rod: a 16 mm hard-chrome rod exits both the front and back covers with the same M14x1.5 male thread at each end. Because the rod-side area is active on both sides of the piston, the output force is equal in both directions - about 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa - with no separate push and pull figures. The 40 mm bore is the largest in the MGD range, and 175 mm sits well inside the 500 mm maximum standard stroke.
The through-rod is the working advantage: it resists piston rotation and side load, keeps stroke-end position repeatable, lets the rear rod end carry a stop or switch flag, or drive a second load while the front end does the main work. The SUS304 stainless barrel and hard-chrome rods suit damp and washdown surroundings, riveted covers keep the body compact, and a fixed anti-impact bumper pad decelerates the stroke end (this is not an adjustable cushion - that is the MGCD). At 1.0 MPa the theoretical maximum is 107.6 kgf, so a realistic vertical working load is about 32 kg using the usual 0.6 safety factor on the 0.5 MPa force.

Where the Airtac MGD Double Rod Mini Cylinder MGD40X175 Is Used
Anti-rotation linear slide
The through-rod keeps the piston from rotating, so the 527.8 N stroke drives a guided slide or turntable indexer square without extra anti-rotation hardware.
Twin-load push
Front and rear M14x1.5 rod ends each deliver the same 527.8 N at 0.5 MPa, so one cylinder can eject parts from two stations at once in a 40 mm force class.
Rear-mounted stop or flag
The back rod end carries a stop block or position flag while the front end does the work; add the S code magnet and a CMSG or DMSG switch for end-of-stroke signalling.
Is the Airtac MGD Double Rod Mini Cylinder MGD40X175 the Right Cylinder?
At 527.8 N per direction at 0.5 MPa, the MGD40X175 is the strongest MGD double-rod cylinder - step down to the MGD32 for lighter loads or up to the MGCD if you need a 50 or 63 mm bore or an adjustable cushion. Choose it when you need anti-rotation guidance, equal force both ways, or a rear rod end for a flag or second load; for a single-rod cylinder pick the MG instead. Mounting is FA flange or LB foot, with I and Y rod knuckles available (no SDB/CB pivot on the double-rod). The 175 mm stroke is standard; strokes to 500 mm need no special order. Order the S code if you want a magnet for CMSG, DMSG or EMSG switches - this model has no magnet, so no sensor can be fitted as-is. On long strokes, keep side load low and support the rod; the cylinder does not hold its position on air loss, so add an external rod lock or pilot check valve for a held 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 MGD40X175 FAQ
Force is equal 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, and the air must be filtered to 40 um. The port is 1/8" and the rod thread is M14x1.5 at both ends.
A rod exits both covers, so both chambers see the rod-side area and the force is identical extending and retracting - the single-rod MG pushes harder than it pulls. The through-rod also resists rotation and side load and lets the rear end carry a flag or second load. This model has fixed bumper pads only (no adjustable cushion - that is the MGCD) and no magnet, so order the S code if you need CMSG, DMSG or EMSG sensing.
