About the Airtac MGC Stainless Steel Mini Cylinder MGC63X450
The AirTAC MGC63X450 is a double acting, JIS-standard round-body mini cylinder with a 63 mm bore and 450 mm stroke, fitted with a variable air cushion at both stroke ends. Unlike the bumper-style MG, the cushion needles can be adjusted to decelerate the piston smoothly near end of travel, so this cylinder tolerates higher piston speeds and heavier moving loads without hammering the covers. At the largest bore in the MG family, it delivers 1557.9 N push and 1400.9 N pull at 0.5 MPa (73 psi), rising to 2181 N push at 0.7 MPa (101 psi), with a theoretical maximum of 317.7 kgf at 1.0 MPa.
Construction follows the JIS mini-cylinder footprint: a SUS304 stainless barrel with covers and stainless block riveted and rolled into place, plus a hard-chrome plated (20 um) carbon-steel rod of 20 mm with an M18x1.5 male thread. Air supply is filtered to 40 um, operating pressure spans 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, temperature range is -20 to +70 C, and speed runs 30-800 mm/s. Ports are 1/4". Note that the cushion only decelerates end of stroke; it is not a lock or brake, so an external rod lock or pilot check valve is recommended for a held load. Mounting is FA flange or LB foot, with I and Y rod knuckles available.

Where the Airtac MGC Stainless Steel Mini Cylinder MGC63X450 Is Used
Pallet push-off stations
The 1557.9 N push force at 0.5 MPa (73 psi) and adjustable cushion let the 63 mm bore shove heavy pallets or totes off a conveyor and stop them gently at end of stroke at speeds up to 800 mm/s.
Light press and forming fixtures
With 2181 N push at 0.7 MPa (101 psi), the MGC63X450 suits staking, crimping and light press work where the variable air cushion absorbs the final approach impact on the tooling.
Vertical lift-and-lower modules
A 450 mm stroke with about 79 kg safe vertical lift capacity (0.5 x 158.8 kgf push) fits gate and platform lifters; pair with a pilot check valve since the cushion is not a load-holding brake.
Is the Airtac MGC Stainless Steel Mini Cylinder MGC63X450 the Right Cylinder?
At 63 mm bore this is the largest MGC offered, with no larger cushioned option in the family; the step up in force is substantial, giving 1557.9 N push at 0.5 MPa (73 psi) versus 981.3 N for the 50 mm bore. Size the load at roughly 0.6 of that push force for a safe working figure of about 934 N, or about 79 kg for vertical lifting (158.8 kgf theoretical push, halved). If your bore is 20-40 mm and you do not need end-of-stroke deceleration, the bumper-style MG is the lower-cost alternative; for 50 and 63 mm, MGC is the only choice. The 450 mm stroke sits within the 500 mm standard range, so no made-to-order surcharge applies, though strokes up to 800 mm can be quoted. Long strokes amplify side loading, so keep the rod aligned or add external guidance. Choose FA flange or LB foot mounting, PT thread (G or NPT on request), and add the S magnet code if you need CMSG, DMSG or EMSG switch detection - this SKU has no magnet, so no sensor can be fitted.

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 MGC63X450 FAQ
At 0.5 MPa (73 psi) it pushes with 1557.9 N and pulls with 1400.9 N; at 0.7 MPa (101 psi) push is 2181 N and pull is 1961.2 N, with a theoretical maximum of 317.7 kgf at 1.0 MPa. A practical rule is to size at about 0.6 of the 0.5 MPa push force, roughly 934 N, or about 79 kg for vertical lifting.
Adjustable cushion needles at both stroke ends throttle the exhaust air to decelerate the piston smoothly near end of travel, which suits higher speeds and heavier moving loads than the fixed bumper MG. The cushion only decelerates; it is not a lock or brake, so use an external rod lock or pilot check valve for a load that must be held on air loss.
