About the Airtac MGC Stainless Steel Mini Cylinder MGC40X100
The AirTAC MGC40X100 is a double acting JIS 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 bumper-type MG, this cushion is adjustable: turn the needle valve to dial in smooth deceleration near end of travel, so the cylinder tolerates higher piston speeds 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 JIS mini pattern: a SUS304 stainless barrel with covers and stainless block riveted and rolled on, plus a hard-chrome plated (20 um) 16 mm carbon-steel rod with an M14x1.5 male thread. The two-way piston seal also stores lubricant, and ports are 1/8". Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C, and speed range 30-800 mm/s on air filtered to 40 um. 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 MGC40X100 Is Used
Conveyor stop and divert
The variable air cushion absorbs the impact of fast-moving cartons or pallets as the rod extends, letting this 40 mm bore cylinder cycle at higher speeds than a bumper-type mini without jarring the mechanism.
Press and clamp fixture
With 628.3 N push at 0.5 MPa (879.6 N at 0.7 MPa), the MGC40X100 clamps jigs and workpieces in machining cells, and the adjustable cushion prevents the platen from slamming home on rapid approach.
Packaging ejector
High-speed eject and push-off stations benefit from the cushioned end of stroke and the 30-800 mm/s speed range, while the SUS304 stainless barrel stands up to washdown-prone packaging environments.
Is the Airtac MGC Stainless Steel Mini Cylinder MGC40X100 the Right Cylinder?
At 40 mm bore, the MGC40X100 sits in the upper-middle of the MGC range: 628.3 N push at 0.5 MPa, roughly 64 kgf, so a sensible safe working load is about 38 kg (0.6 x push force), or around 32 kg for vertical lifting. Step down to the 32 mm bore (402.2 N push) for lighter duty, or up to 50 mm (981.3 N) and 63 mm (1557.9 N) when more force is needed; for 20-40 mm bores without cushioning needs, the bumper-type MG is the lower-cost alternative. The 100 mm stroke is well within the 500 mm maximum standard stroke, and non-standard strokes up to 800 mm are made to order. Order FA flange or LB foot mounting, add I or Y rod knuckles if the load pivots, and add the S code if you want the magnet for CMSG / DMSG / EMSG sensors - without it no sensor can be mounted. At 30-800 mm/s, keep side loads off the rod on longer strokes and use external guides where needed.

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 MGC40X100 FAQ
At 0.5 MPa it pushes with 628.3 N and pulls with 527.8 N; at 0.7 MPa those rise to 879.6 N push and 738.9 N pull, and the theoretical maximum is 128.1 kgf at 1.0 MPa. A practical safe working load is about 38 kg (0.6 of the push force), or roughly 32 kg for vertical lifting.
Yes, both ends have a variable air cushion - adjust the needle to control end-of-stroke deceleration; it is not a fixed bumper pad. However, the cushion only slows the piston near the end of travel and is not a lock or brake, so fit an external rod lock or pilot check valve if the load must stay in place on air loss. The -S option adds the magnet needed for CMSG / DMSG / EMSG sensors.
