About the Airtac MGC Stainless Steel Mini Cylinder MGC63X50S
The AirTAC MGC63X50S is a double acting, JIS-standard round-body mini cylinder with a 63 mm bore and 50 mm stroke, fitted with a variable air cushion at both stroke ends. Unlike the bumper-style MG, this cushion is adjustable: turn the cushion needle to dial in smooth piston deceleration near end of travel, which lets the MGC run at higher speeds and handle heavier moving loads without hammering the covers. With the largest bore in the MG family, it delivers a push force of 1557.9 N and a pull force of 1400.9 N at 0.5 MPa (72 psi), rising to 2181 N push at 0.7 MPa (101 psi), with a theoretical maximum of 317.7 kgf at 1.0 MPa (145 psi).
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 carbon-steel rod with an M18x1.5 male thread and 1/4" ports. The two-way piston seal also stores lubricant for long service life. Operating pressure spans 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, speed range 30-800 mm/s, and temperature -20 to +70 C on air filtered to 40 um. The fitted magnet (S code) accepts CMSG, DMSG or EMSG switches for position feedback. 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 MGC63X50S Is Used
Heavy press and staking stations
The 1557.9 N push at 0.5 MPa (72 psi) gives compact jigs real pressing force, and the variable air cushion absorbs the final approach so the tooling does not hammer the covers at cycle end.
High-speed conveyor pushers
Running at up to 800 mm/s, the adjustable cushion decelerates heavy product pushes smoothly, making this bore a good fit for diverting or indexing larger cartons on transfer lines.
Pallet and fixture clamping
With up to 317.7 kgf theoretical force at 1.0 MPa (145 psi), the MGC63X50S clamps fixtures or gates firmly, while the magnet and CMSG/DMSG/EMSG switches confirm clamp and unclamp positions.
Is the Airtac MGC Stainless Steel Mini Cylinder MGC63X50S the Right Cylinder?
At 63 mm bore this is the largest MGC available, so size up from smaller bores when force is the driver: the MGC50 pushes 981.3 N at 0.5 MPa (72 psi) while this model pushes 1557.9 N, roughly 59% more, and there is no larger cushioned bore in the family. If your bore falls in the 20-40 mm range and you do not need end-of-stroke deceleration, the bumper-style MG is the lower-cost alternative. The variable air cushion is the main reason to choose MGC over MG when piston speed or moving mass would otherwise slam the covers. Mount with the FA flange or LB foot, and add I or Y rod knuckles where the load pivots. The S code means the magnet is already fitted, so CMSG, DMSG or EMSG switches can be clipped on at any time. At 50 mm stroke the compact envelope suits tight spaces, but keep side loads off the 20 mm rod on any stroke length; guide external slides if the load is not aligned. Strokes beyond the 500 mm standard maximum are made to order up to 800 mm.

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 MGC63X50S FAQ
At 0.5 MPa (72 psi) it pushes 1557.9 N and pulls 1400.9 N. At 0.7 MPa (101 psi) push rises to 2181 N and pull to 1961.2 N. The theoretical maximum is 317.7 kgf at 1.0 MPa (145 psi). For safe working loads, size around 60% of the push force, which is roughly 95 kg of continuous push duty at 0.5 MPa (72 psi).
The cushion at both stroke ends is adjustable: a needle valve meters the exhaust near end of travel to decelerate the piston smoothly, so you can run faster strokes or move heavier loads without impact. It only decelerates, it is not a lock or brake, and the cylinder will not hold position if air is lost. For a held load, add an external rod lock or pilot check valve.
