About the Airtac MGC Stainless Steel Mini Cylinder MGC40X100S
The AirTAC MGC40X100S is a double acting, JIS-standard round-body mini cylinder with a 40 mm bore and 100 mm stroke, built with a variable air cushion at both stroke ends. Unlike the fixed bumper pad on the plain MG, this adjustable cushion lets you tune the needle valve to decelerate the piston smoothly near end of travel, so the 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 push and 527.8 N pull, rising to 879.6 N push at 0.7 MPa, with a theoretical maximum of 128.1 kgf at 1.0 MPa.
Construction follows the MG family recipe: a SUS304 stainless barrel with covers and stainless block riveted and rolled onto it, plus a hard-chrome plated (20 um) 16 mm carbon-steel rod with an M14x1.5 male thread and a two-way piston seal that also stores lubricant. Air supply should be filtered to 40 um; operating pressure spans 0.15-1.0 MPa (22-145 psi) with proof pressure of 1.5 MPa (215 psi), and the temperature range is -20 to +70 C. The fitted magnet (the S in the code) allows CMSG, DMSG or EMSG reed switches for position detection. As a rule of thumb, keep vertical lifting loads to about 0.6 of the push force, roughly 38 kg here, for a safe working margin.

Where the Airtac MGC Stainless Steel Mini Cylinder MGC40X100S Is Used
Conveyor stop and divert
The variable air cushion absorbs the impact of fast-moving cartons or pallets as the 40 mm bore rod (628.3 N push at 0.5 MPa) extends to stop or divert product, protecting the cylinder covers at high cycle rates.
Fixture clamping on machining lines
With 879.6 N push at 0.7 MPa and smooth deceleration at end of stroke, the MGC40X100S clamps jigs and fixtures on CNC or assembly fixtures without jarring the setup, while the fitted magnet feeds position signals to the PLC.
Palletizer push-off arm
In palletizing cells the cushioned stroke end lets the push-off arm run at speed and still set loads down gently; the SUS304 barrel and hard-chrome rod stand up to dusty warehouse air with 40 um filtered supply.
Is the Airtac MGC Stainless Steel Mini Cylinder MGC40X100S the Right Cylinder?
At 40 mm bore this is the top of the mid-size MGC range: 628.3 N push and 527.8 N pull at 0.5 MPa (about 64 kgf and 54 kgf), or 879.6 N push at 0.7 MPa. If you need more force, step up to the 50 mm bore (981.3 N push at 0.5 MPa) or the 63 mm bore (1557.9 N), both offered only in the cushioned MGC/MGCD types; if you want a smaller package, the 32 mm bore gives 402.2 N. For 20-40 mm work where end-of-stroke damping is not needed, the bumper-type MG is the no-cushion alternative at a lower cost. Choose this MGC when your cycle runs fast or carries a moving load that would slam the covers of a bumper cylinder. Mounting options are the LB foot and FA flange, with I and Y rod knuckles available; the PT thread port is 1/8". The S code means the magnet is already fitted for CMSG/DMSG/EMSG switches. The 100 mm stroke is well inside the 500 mm standard limit, but on long strokes keep the rod side load low or add external guidance to protect the hard-chrome 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 MGC40X100S FAQ
At 0.5 MPa the 40 mm bore gives 628.3 N push and 527.8 N pull; at 0.7 MPa it gives 879.6 N push and 738.9 N pull. The theoretical maximum is 128.1 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure. For vertical lifting, keep the load to roughly 38 kg, about 0.6 of the push force.
The cushion at both stroke ends is adjustable: turn the cushion needle to meter the exhausting air and decelerate the piston smoothly near end of travel, which is ideal at higher speeds or with heavier moving loads. It is an adjustable air cushion, not a fixed bumper pad. Note that the cushion only decelerates the stroke end; it is not a lock or brake, and the cylinder will not hold position on air loss, so use an external rod lock or pilot check valve for a held load.
