About the Airtac MG Stainless Steel Mini Air Cylinder MG40X75
With the largest bore in the MG family, the MG40X75 delivers 628.3 N of push and 527.8 N of pull at 0.5 MPa, rising to 879.6 N at 0.7 MPa. This double acting JIS round-body mini cylinder uses a riveted SUS304 stainless barrel with a hard-chrome plated 16 mm rod, so it shrugs off washdown and damp shop air far better than painted-steel minis. The fixed anti-impact bumper pad at each end softens the direction change at stroke ends; it decelerates only and is not an adjustable air cushion.
For real-world sizing, plan on roughly 377 N (about 38 kg of force) of usable work at 0.5 MPa rather than the full 628.3 N rating. Held vertically with a 2:1 margin, it lifts about 32 kg. Because the MG follows the JIS mini-cylinder standard, standard JIS brackets and I/Y rod knuckles bolt straight on, and the 75 mm stroke runs at 30-800 mm/s on air filtered to 40 um.

Where the Airtac MG Stainless Steel Mini Air Cylinder MG40X75 Is Used
Carton press-down station
The 628.3 N push at 0.5 MPa seats flaps and presses cartons on a packaging line, with the bumper pad quieting each 75 mm downstroke.
Small fixture clamping
Clamps jigs or weld fixtures on machining cells; the 40 mm bore gives about 38 kg of usable force at 0.5 MPa with margin to spare.
Battery-lift assist arm
Lifts about 32 kg vertically with a 2:1 margin - enough for battery packs or small castings on assembly benches.
Is the Airtac MG Stainless Steel Mini Air Cylinder MG40X75 the Right Cylinder?
At 40 mm bore this is the top of the standard MG range: 628.3 N push at 0.5 MPa versus 402.2 N for the 32 mm bore below it. If your load needs more than 879.6 N at 0.7 MPa, step up to the cushioned MGC series, which extends the range to 50 and 63 mm bores. Note that a plain MG does not hold position when air is lost - the piston drifts - so add an external rod lock or a pilot check valve for held loads.
This SKU has no magnet, so CMSG, DMSG or EMSG switches cannot be fitted; order the S code (MG40X75S...) if you need position sensing. Mount it with LB foot, FA flange, CB clevis or SDB pivot brackets. The 75 mm stroke is well inside the 500 mm standard limit, but keep side loads off the 16 mm rod if the tooling overhangs.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting (LB / FA / CB / SDB) & knuckle
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 MG Stainless Steel Mini Air Cylinder MG40X75 FAQ
At 0.5 MPa it pushes with 628.3 N and pulls with 527.8 N; at 0.7 MPa those rise to 879.6 N push and 738.9 N pull. The theoretical maximum is 128.1 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, and speed runs 30-800 mm/s.
Not on this SKU. Without the S code there is no built-in magnet, so CMSG, DMSG or EMSG reed switches cannot detect the piston. Order MG40X75S for sensing. The cylinder itself is a JIS round-body stainless unit with a 1/8" port, M14x1.5 male rod thread and fixed bumper pads - not an adjustable cushion.
