About the Airtac MGC Stainless Steel Mini Cylinder MGC40X500
The AirTAC MGC40X500 is a JIS-standard round-body mini cylinder, double acting, with a variable air cushion at both stroke ends. The 40 mm bore delivers 628.3 N push and 527.8 N pull at 0.5 MPa (72 psi), rising to 879.6 N push at 0.7 MPa (101 psi), with a theoretical maximum of 128.1 kgf at 1.0 MPa. The adjustable cushion needles let you dial in smooth deceleration near each end of travel, so this cylinder handles higher piston speeds and heavier moving loads than the fixed-bumper MG without hammering the covers.
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 carbon-steel rod (16 mm diameter, M14x1.5 male thread) and a two-way piston seal that also stores lubricant. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), from -20 to +70 C, at speeds of 30-800 mm/s. 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. Mount with FA flange or LB foot, add I or Y rod knuckles, and order the -S magnet option if you later want CMSG, DMSG or EMSG sensing.

Where the Airtac MGC Stainless Steel Mini Cylinder MGC40X500 Is Used
High-speed pusher on packaging lines
The variable air cushion absorbs end-of-stroke momentum at speeds up to 800 mm/s, letting the 40 mm bore (628.3 N push at 0.5 MPa) cycle fast without slamming the covers.
Conveyor divert and stop stations
Adjustable deceleration at both ends protects lightweight diverters and stops, while the 500 mm stroke reaches across wide belts and the SUS304 barrel resists washdown dust.
Small press and forming fixtures
With 879.6 N push at 0.7 MPa (101 psi) and smooth cushioned approach, the MGC40X500 suits light staking, clinching and forming jigs where impact control matters.
Is the Airtac MGC Stainless Steel Mini Cylinder MGC40X500 the Right Cylinder?
At 40 mm bore the MGC40X500 sits mid-range in the cushioned MGC family: it gives 628.3 N push at 0.5 MPa, roughly 64 kgf, so a safe working load is about 38 kg (0.6 of push force) and around 32 kg if lifting vertically. Step down to MGC32 for lighter duty (402.2 N push at 0.5 MPa) or up to MGC50 (981.3 N) and MGC63 (1557.9 N) when you need more force; MGC50 and 63 are offered only in the cushioned MGC/MGCD builds. If your application does not need end-of-stroke deceleration, the plain bumper MG in 40 mm bore is the no-cushion alternative. Choose PT thread (blank), G or NPT, mount via FA flange or LB foot, and add the S magnet code if position sensing with CMSG/DMSG/EMSG switches is planned. The 500 mm stroke is the maximum standard stroke for this bore, so long strokes put extra side load on the 16 mm rod: guide the load externally and consider alignment couplers or knuckles (I or Y) to protect the bearing.

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 MGC40X500 FAQ
At 0.5 MPa (72 psi) it pushes with 628.3 N and pulls with 527.8 N; at 0.7 MPa (101 psi) push is 879.6 N and pull 738.9 N. The theoretical maximum is 128.1 kgf at 1.0 MPa. A practical safe working load is about 0.6 of the 0.5 MPa push force, roughly 38 kg.
Needle valves at each end throttle the exhaust so the piston decelerates smoothly before the cover; you adjust the cushion to suit speed and load. It only slows the stroke end, however, and does not lock or hold position on air loss, so fit an external rod lock or pilot check valve for a held load. The SUS304 barrel and hard-chrome 16 mm rod keep the build corrosion resistant, and the -S magnet option enables CMSG/DMSG/EMSG switches.
