About the Airtac MGC Stainless Steel Mini Cylinder MGC63X250
The AirTAC MGC63X250 is a double acting JIS round-body mini cylinder with a 63 mm bore and 250 mm stroke, fitted with a variable air cushion at both stroke ends. The cushion needles let you dial in smooth end-of-stroke deceleration, so this bore can run at higher speeds and move heavier loads than the bumper-type MG without hammering the covers. At 0.5 MPa it delivers 1557.9 N push and 1400.9 N pull, rising to 2181 N push at 0.7 MPa, with a theoretical maximum of 317.7 kgf at 1.0 MPa. As the largest bore in the MGC family, it shares the 20 mm rod and M18x1.5 male rod thread with the 50 mm bore but offers substantially more force.
Construction follows the JIS mini-cylinder format: a SUS304 stainless barrel with covers and stainless block riveted and rolled onto it, plus a hard-chrome plated (20 um) carbon-steel rod and a two-way piston seal that also stores lubricant. Operating range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, air filtered to 40 um, -20 to +70 C, and speeds of 30-800 mm/s. Ports are 1/4" with PT threading (G and NPT available). Note that the air cushion only decelerates the piston near end of stroke; it is not a lock or brake, so an external rod lock or pilot check valve is recommended for holding a load against air loss.

Where the Airtac MGC Stainless Steel Mini Cylinder MGC63X250 Is Used
Pallet pusher on transfer carts
The 1557.9 N push at 0.5 MPa shunts loaded pallets between conveyor lanes, and the variable air cushion absorbs the momentum at end of stroke so the 250 mm travel does not slam the covers at speed.
Press-fit and staking station
With 2181 N push at 0.7 MPa, the 63 mm bore handles light press-fit, staking and crimping jobs, while the adjustable cushion damps the return stroke for smoother cycling.
Heavy gate and chute diverter
Moving heavy slide gates or diverter flaps at up to 800 mm/s, the cushioned ends prevent hard stops, and the LB foot or FA flange mounting suits fixed machine frames.
Is the Airtac MGC Stainless Steel Mini Cylinder MGC63X250 the Right Cylinder?
At 63 mm bore this is the top of the MGC range - there is no larger cushioned option in the family. Size by the 0.5 MPa push force of 1557.9 N (about 158.8 kgf); a safe working load rule of thumb is roughly 0.6 of that, so plan on about 95 kg for horizontal pushes with margin, or roughly 79 kg for vertical lifting duty. If your application sits between bores, the 50 mm MGC gives 981.3 N push at 0.5 MPa, so the step up to 63 mm buys about 59 percent more force. If you do not need end-of-stroke deceleration, the bumper-type MG (bores 20-40 only) is the no-cushion alternative, but it cannot match this force class. The 250 mm stroke is within the 500 mm standard range; strokes up to 800 mm are made to order. Mount with FA flange or LB foot, add I or Y rod knuckles for couplings, and specify the S code if you want CMSG, DMSG or EMSG magnetic sensors - this SKU has no magnet, so no sensor can be fitted. On long strokes, guide side loads externally to protect the 20 mm rod.

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 MGC63X250 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 push and 1961.2 N pull. The theoretical maximum is 317.7 kgf at 1.0 MPa. For sizing, treat about 0.6 of the 0.5 MPa push force as a safe working load.
Adjustable cushion needles at both ends throttle the exhaust near end of stroke, decelerating the piston smoothly - useful at higher speeds or with heavy moving loads. It only decelerates; it is not a lock or brake. For a held load, add an external rod lock or pilot check valve. The SUS304 stainless barrel and hard-chrome rod suit humid or washdown-adjacent environments.
