About the Airtac MG Stainless Steel Mini Air Cylinder MG40X700S
With a 40 mm bore pushing 628.3 N at 0.5 MPa (879.6 N at 0.7 MPa), this MG40X700S is the strongest member of the AirTAC MG family, built as a double acting JIS round-body mini cylinder with a 700 mm made-to-order stroke. The riveted SUS304 stainless barrel pairs with a 16 mm hard-chrome plated rod (M14x1.5 male thread), so the body shrugs off damp, washdown-prone and outdoor conditions that quickly ruin painted-steel minis.
Because the footprint follows the JIS mini-cylinder standard, this bore drops onto standard JIS brackets and I/Y rod knuckles without redesign work. The 700 mm stroke exceeds the 500 mm catalogue maximum, so it is produced to order - and at this length, keep side loads off the rod and guide the load externally. The fitted magnet works with CMSG, DMSG or EMSG switches, and the fixed anti-impact bumper pads soften each end of travel. At 0.5 MPa the push force equals about 64 kgf, so halving for a 2:1 margin gives roughly 32 kg of safe vertical lift.

Where the Airtac MG Stainless Steel Mini Air Cylinder MG40X700S Is Used
Vertical lift in packaging machinery
The 628.3 N push at 0.5 MPa lifts roughly 32 kg vertically with a 2:1 margin - enough for raising filled cartons or trays on a long 700 mm lift stroke.
Long-stroke pusher on conveyor lines
A 700 mm stroke pushes diverted cartons or totes across a wide conveyor; the magnet and CMSG switch confirm end-of-stroke position at both ends.
Washdown fixture clamping in food plants
The SUS304 stainless barrel and chrome rod tolerate routine hose-down in food or beverage cells where painted mini cylinders corrode and seize.
Is the Airtac MG Stainless Steel Mini Air Cylinder MG40X700S the Right Cylinder?
Size check: the 32 mm bore MG32 delivers 402.2 N push at 0.5 MPa, while stepping up means the cushioned MGC in 50 or 63 mm - so the 40 mm MG sits at the top of the base range with 628.3 N push and 527.8 N pull at 0.5 MPa. If your cycle slams heavy loads at high speed, the MGC variant adds an adjustable air cushion instead of the fixed bumper.
Mount it with LB foot, FA flange, CB clevis or SDB pivot brackets, and add I or Y rod knuckles for the joint. Note that a plain MG drifts when air is lost or the valve centres - the bumpers only soften the stroke ends - so fit an external rod lock or pilot check valve where a load must stay put. Operating window is 0.15-1.0 MPa (22-145 psi), 30-800 mm/s, -20 to +70 C, on air filtered to 40 um.

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 MG40X700S FAQ
At 0.5 MPa it pushes 628.3 N and pulls 527.8 N; at 0.7 MPa, 879.6 N push and 738.9 N pull. Theoretical maximum is 128.1 kgf at 1.0 MPa. In practice, plan work around 60 percent of the push figure - about 377 N - and for vertical lifting halve the 64 kgf equivalent to roughly 32 kg for a 2:1 margin.
No - the MG bore 40 catalogue maximum is 500 mm, so 700 mm is a made-to-order non-standard stroke (non-standard strokes run up to 800 mm). The S in MG40X700S means the magnet is built in, so CMSG, DMSG or EMSG reed/electronic switches mount directly on the barrel; a SKU without the S cannot take these sensors.
