About the Airtac MGC Stainless Steel Mini Cylinder MGC63X350
The AirTAC MGC63X350 is a double acting JIS-standard round-body mini cylinder with a 63 mm bore and 350 mm stroke, fitted with a variable air cushion at both stroke ends. The cushion needle is adjustable, so you can dial in smooth deceleration of the piston near end of travel - a real advantage at higher piston speeds or with heavier moving loads, where a fixed pad would let the piston hammer the covers. At 0.5 MPa this bore 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.
Construction follows the JIS mini-cylinder pattern: a SUS304 stainless barrel with covers and stainless block riveted and rolled onto it, plus a hard-chrome plated 20 um carbon-steel rod (20 mm diameter, male thread M18x1.5). Ports are 1/4". Operating pressure is 0.15-1.0 MPa (22-145 psi) with proof pressure 1.5 MPa (215 psi), temperature range -20 to +70 C, and speed 30-800 mm/s on air filtered to 40 um. The two-way piston seal also stores lubricant for low-maintenance running. Note that the cushion only decelerates the stroke end - it is not a lock or brake, and the cylinder does not hold position on air loss, so use an external rod lock or pilot check valve 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 MGC63X350 Is Used
Pallet pusher on conveyor ends
The 1557.9 N push at 0.5 MPa moves heavy pallets or totes off a line, and the variable air cushion absorbs the momentum at stroke end so loads are not slammed into the stop.
Press-fit and staking station
With up to 2181 N at 0.7 MPa, the MGC63X350 suits light press-fit, staking and clinching where adjustable deceleration protects tooling and part seating at speed.
Lift-and-lower fixture clamp
FA flange or LB foot mounting with I/Y knuckles fits clamping and lifting fixtures; the cushion smooths descent, though an external check valve is needed to hold a load on air loss.
Is the Airtac MGC Stainless Steel Mini Cylinder MGC63X350 the Right Cylinder?
At 63 mm bore this is the largest MGC offered - there is nothing bigger in the cushioned MG family, so choose it when 0.5 MPa push force of 1557.9 N (about 158.8 kgf) is your baseline. Rule of thumb: keep dynamic working load near 0.6 of push force, roughly 95 kg, and for vertical lifting halve it again to about 79 kg. If you need less force, step down to MGC50 (981.3 N push at 0.5 MPa); for bores 20-40 the bumper-type MG is the no-cushion alternative, but only MGC and MGCD exist in 50 and 63. The 350 mm stroke sits within the 500 mm standard range for this bore; strokes to 800 mm are made to order. Order the -S magnet option if you want position sensing with CMSG, DMSG or EMSG switches - without the magnet no sensor can be mounted. Mount with FA flange or LB foot, add I or Y rod knuckles as needed, and on a long stroke like this keep side load on the rod minimal or guide the load externally.

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 MGC63X350 FAQ
At 0.5 MPa it pushes 1557.9 N and pulls 1400.9 N; at 0.7 MPa push is 2181 N and pull 1961.2 N. The theoretical maximum is 317.7 kgf at 1.0 MPa. For safe dynamic loading, size around 0.6 of the push force, about 95 kg.
Needle valves at both ends meter the exhaust near end of stroke, giving adjustable deceleration - ideal at speeds up to 800 mm/s. It is not a brake and will not hold position on air loss. The -S magnet option enables CMSG, DMSG or EMSG switches; this SKU has no magnet, so no sensor can be mounted.
