Airtac MG Stainless Steel Mini Air Cylinder MG40X750S
The AirTAC Airtac MG Stainless Steel Mini Air Cylinder MG40X750S is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 750mm stroke, 1/8" air ports and a SUS304 stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.

About the Airtac MG Stainless Steel Mini Air Cylinder MG40X750S
With a 40 mm bore pushing 628.3 N at 0.5 MPa (879.6 N at 0.7 MPa), the MG40X750S is a double acting JIS round-body mini cylinder built for long-travel work: 750 mm of stroke on a 16 mm hard-chrome plated rod, with a 1/8" port and a built-in magnet. The 750 mm stroke is beyond the 500 mm standard range, so this length is made to order. The SUS304 stainless barrel and riveted covers shrug off damp, washdown-prone surroundings far better than painted-steel minis, and the JIS mounting footprint accepts standard JIS mini-cylinder brackets and rod knuckles.
In practice, budget roughly 377 N (about 60% of the 0.5 MPa push) for real work at 0.5 MPa, which means this cylinder lifts about 32 kg vertically with a 2:1 margin (theoretical 64 kg). The fixed anti-impact bumper pads soften the stroke ends at speed but do not cushion adjustably or hold a load - if air is lost the rod drifts freely, so add an external rod lock or pilot check valve where a held position matters. The fitted magnet lets CMSG, DMSG or EMSG switches report end positions directly.

Where the Airtac MG Stainless Steel Mini Air Cylinder MG40X750S Is Used
Long-stroke conveyor stopper
The 628.3 N push at 0.5 MPa (about 377 N usable) is enough to raise a stopper blade under cartons on a 750 mm travel gate in a packaging line, and the stainless barrel tolerates routine washdown.
Carton elevator pusher
Lifting about 32 kg vertically with a 2:1 margin, this cylinder suits a lift-and-transfer module that raises trays between two conveyor levels over a long vertical travel.
Position-fed sliding door actuator
With the built-in magnet and CMSG or DMSG switches at both ends, the MG40X750S gives confirmed open/closed signals on a sliding guard door or gate in a factory cell.
Is the Airtac MG Stainless Steel Mini Air Cylinder MG40X750S the Right Cylinder?
Step up or down by force: the MG32 bore delivers 402.2 N push at 0.5 MPa, while this 40 mm bore gives 628.3 N - a 56% jump. The base MG tops out at 40 mm; if you need more force or an adjustable air cushion for high-speed stops, move to the MGC series in 50 or 63 mm. At 750 mm stroke, keep side loads off the rod and guide the load externally, since rod bending grows quickly over long travels. Mount with LB foot, FA flange, CB clevis or SDB pivot (with CB), and pair with I or Y rod knuckles. The S in the code means the magnet is already fitted - order CMSG, DMSG or EMSG switches separately if you need position sensing.

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 MG40X750S FAQ
At 0.5 MPa it pushes 628.3 N and pulls 527.8 N; at 0.7 MPa it pushes 879.6 N and pulls 738.9 N. The theoretical maximum is 128.1 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, and speed runs 30-800 mm/s.
Yes. The S in the model code means a magnet is built into the piston, so AirTAC CMSG, DMSG or EMSG reed/electronic switches can be clipped onto the stainless barrel to signal rod position. Without the magnet option no sensor would trigger, but this model is sensor-ready as ordered.
