About the Airtac MGC Stainless Steel Mini Cylinder MGC40X150S
The AirTAC MGC40X150S is a double acting, JIS-standard round-body mini cylinder with a 40 mm bore and 150 mm stroke, fitted with a variable air cushion at both stroke ends. Unlike the bumper-equipped MG, the cushion needles can be adjusted to decelerate the piston smoothly near end of travel, so this cylinder tolerates higher piston speeds (up to 800 mm/s) and heavier moving loads without hammering the covers. At 0.5 MPa it delivers 628.3 N of push force and 527.8 N of pull force, rising to 879.6 N on the push stroke at 0.7 MPa.
Construction follows the JIS mini-cylinder footprint: a SUS304 stainless barrel with covers and stainless block riveted and rolled onto it, plus a hard-chrome plated (20 um) carbon-steel rod of 16 mm diameter with an M14x1.5 male thread. The two-way piston seal also stores lubricant, and ports are 1/8". Because the S code is included, a magnet is fitted and CMSG, DMSG or EMSG switches can be mounted for position detection. Note that the cushion only decelerates the stroke end; it is not a lock or brake, so use an external rod lock or pilot check valve if the load must be held on air loss.

Where the Airtac MGC Stainless Steel Mini Cylinder MGC40X150S Is Used
High-speed conveyor stop and push
The variable air cushion absorbs the momentum of fast-moving cartons at stroke end, letting this 40 mm bore (628.3 N push at 0.5 MPa) cycle at up to 800 mm/s without cover impact.
Pressing and forming fixtures
With 879.6 N of push force at 0.7 MPa and adjustable end-of-stroke deceleration, the MGC40X150S suits light pressing, staking and forming where a hard stop would damage tooling.
Palletizing lift-and-push modules
Around 38 kg safe vertical load (about 0.6 of push force) plus the fitted magnet for CMSG/DMSG/EMSG switches make it a compact actuator for layer-forming and transfer heads.
Is the Airtac MGC Stainless Steel Mini Cylinder MGC40X150S the Right Cylinder?
At 40 mm bore this is the upper-middle of the MGC range: 628.3 N push at 0.5 MPa (about 64 kgf), so a sensible working load is roughly 38 kg for vertical lifting (about 0.6 of the push force) or around 32 kgf at half the theoretical 128.1 kgf maximum. If you need less force, MGC32 offers 402.2 N push at 0.5 MPa; if you need more, MGC50 reaches 981.3 N and MGC63 reaches 1557.9 N. For bores 20 to 40 the plain MG is the no-cushion alternative if your application runs slowly with light loads and does not need adjustable deceleration. The 150 mm stroke is well inside the 500 mm standard range for this bore (non-standard strokes up to 800 mm are made to order). Mount with the FA flange or LB foot, add I or Y rod knuckles if the tooling needs a pivot, and choose PT, G or NPT ports. For long strokes, guide the load externally to keep side load off the rod.

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 and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MGC Stainless Steel Mini Cylinder MGC40X150S FAQ
At 0.5 MPa it pushes with 628.3 N and pulls with 527.8 N; at 0.7 MPa those figures 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 a 1.5 MPa (215 psi) proof pressure.
Needle valves at both ends meter the exhaust near end of stroke, giving adjustable deceleration so higher speeds and heavier moving loads are handled smoothly; it is an adjustable air cushion, not a fixed bumper pad. The cushion does not lock the piston, so for a load that must be held on air loss add an external rod lock or pilot check valve.
