About the Airtac MGC Stainless Steel Mini Cylinder MGC63X400S
The AirTAC MGC63X400S is a double acting, JIS-standard round-body mini cylinder with a 63 mm bore and 400 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 piston deceleration near end of travel, so the cylinder tolerates higher speeds (up to 800 mm/s) and heavier moving loads without hammering the covers. At 0.5 MPa it delivers 1557.9 N of push force and 1400.9 N of pull, rising to 2181 N and 1961.2 N at 0.7 MPa - the largest force in the MGC range.
Construction follows the JIS mini-cylinder footprint: a SUS304 stainless barrel with covers and stainless block riveted and rolled into place, plus a 20 mm hard-chrome plated rod (M18x1.5 male thread) and a two-way piston seal that also stores lubricant. The fitted magnet (the S in the code) allows CMSG, DMSG or EMSG reed switches for end-of-stroke sensing. Air supply should be filtered to 40 um, with an operating pressure of 0.15-1.0 MPa (22-145 psi), proof pressure of 1.5 MPa (215 psi) and a temperature range of -20 to +70 C. Ports are 1/4"; mounting options are FA flange or LB foot, with I and Y rod knuckles available.

Where the Airtac MGC Stainless Steel Mini Cylinder MGC63X400S Is Used
Heavy pallet pusher on conveyors
The 1557.9 N push force at 0.5 MPa and adjustable end cushion let a 63 mm bore nudge heavy pallets onto rollers at speed without jarring the frame at stroke end.
Baling and compaction slides
With 2181 N of push at 0.7 MPa and a variable air cushion to soften impact, this cylinder suits compacting scrap, trim or packaging waste in mid-duty presses.
Clamping fixtures on machining lines
The hard-chrome rod and stainless barrel stand up to coolant mist, while the cushion absorbs clamp inertia and the fitted magnet confirms clamp position via CMSG switches.
Is the Airtac MGC Stainless Steel Mini Cylinder MGC63X400S the Right Cylinder?
At 63 mm bore this is the top of the MGC force ladder: 1557.9 N push at 0.5 MPa, roughly 158.8 kgf. A practical rule of thumb is to size the load at about 0.6 of the push force, so keep continuous loads near 95 kg or less; for vertical lifting, halve that to around 79 kg. If you need less force, step down to the 50 mm bore (981.3 N push at 0.5 MPa); there is no larger MGC bore. For 20-40 mm bores without cushioning, the bumper-type MG is the alternative. The 400 mm stroke sits within the 500 mm standard range, but at this length support the rod or avoid side loads to protect the bushings. Choose FA flange or LB foot mounting, add I or Y knuckles if the tooling pivots, and note that the fitted magnet means CMSG/DMSG/EMSG switches can be clipped on. Remember the air cushion only decelerates the stroke ends - it is not a lock, so use an external rod lock or pilot check valve if the load must be held on air loss.

- ✓ Mounting (LB / FA) & knuckle
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 MGC63X400S FAQ
At 0.5 MPa it pushes with 1557.9 N and pulls with 1400.9 N; at 0.7 MPa those rise to 2181 N and 1961.2 N. The theoretical maximum is 317.7 kgf at 1.0 MPa. For continuous duty, size the load at about 0.6 of the push force - roughly 95 kg - and for vertical lifting halve that to about 79 kg.
The cushion is an adjustable air restriction at both stroke ends: turn the needle to decelerate the piston smoothly, which allows higher speeds and heavier moving loads than the bumper-type MG. It only slows the piston near end of travel - it is not a lock or brake, and the cylinder will not hold position on air loss. Fit an external rod lock or pilot check valve for a held load.
