About the Airtac MGC Stainless Steel Mini Cylinder MGC63X450S
The AirTAC MGC63X450S is a double acting, JIS-standard round-body mini cylinder with a 63 mm bore and a 450 mm stroke, and it is the largest bore in the cushioned MGC family. At both stroke ends a variable air cushion is fitted: turn the cushion needle and you dial in exactly how hard the piston decelerates, so this cylinder can run at higher speeds and move heavier loads than the bumper-type MG without hammering the covers. The cushion is adjustable, not a fixed pad, which is what separates MGC from the plain MG series. With 1557.9 N of push force at 0.5 MPa, this is the strongest MGC in the lineup.
Construction follows the JIS mini-cylinder footprint: 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) and a two-way piston seal that also stores lubricant. Air supply should be filtered to 40 um, operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), temperature range -20 to +70 C, and speed 30-800 mm/s. The fitted magnet (the S in the code) accepts CMSG, DMSG or EMSG switches, and mounting is via FA flange or LB foot with I and Y rod knuckles available. Note that the air cushion only decelerates end of stroke; 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 MGC63X450S Is Used
Heavy pallet pusher on transfer carts
The 1557.9 N push at 0.5 MPa moves loaded pallets or die carts between stations, while the variable air cushion absorbs the momentum of the heavy mass at end of stroke instead of slamming the covers.
High-speed conveyor diverters
Running at up to 800 mm/s, the adjustable cushion lets the diverter arm decelerate smoothly into its end position at line speed, avoiding bounce and noise that a fixed-pad cylinder would produce.
Press-fit and staking stations
With 2181 N push at 0.7 MPa (about 222 kgf), the 63 mm bore handles light press-fit, staking and crimping tasks, and the cushion gives a controlled approach at the workpiece.
Is the Airtac MGC Stainless Steel Mini Cylinder MGC63X450S the Right Cylinder?
At 63 mm bore this is the top of the MGC range - there is no larger cushioned model - so size it when your load needs serious force in a round-body JIS package. The 0.5 MPa push force of 1557.9 N equals about 158.8 kgf; applying the usual 0.6 safety factor gives a practical working load near 95 kg, and for vertical lifting halve it to roughly 79 kg. If your application is slower and lighter, the bumper-type MG (bores 20-40 only) is the no-cushion alternative, but it cannot match this force class. The 450 mm stroke sits within the 500 mm maximum standard stroke for this bore, so it ships as a standard item; strokes beyond 500 mm up to 800 mm are made to order. At this stroke length, keep side loads on the rod minimal or add external guidance. Choose the FA flange or LB foot mounting, specify G or NPT thread instead of the default PT if needed, and remember the S code already includes the magnet for CMSG/DMSG/EMSG position sensing.

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 MGC63X450S 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. Theoretical maximum force is 317.7 kgf at 1.0 MPa. For sizing, take about 0.6 of the 0.5 MPa push force as a safe working load - roughly 95 kg horizontally, or about 79 kg for vertical lifting.
The cushion at each stroke end is adjusted with a needle valve: closing it traps and meters air so the piston decelerates smoothly before reaching the cover, which is ideal at high speed or with heavy moving loads. It is adjustable, not a fixed bumper pad. It only decelerates the stroke end - it is not a lock or brake, and the cylinder will not hold position on air loss, so fit an external rod lock or pilot check valve for a held load. The SUS304 stainless barrel and hard-chrome rod suit this to washdown-prone and corrosive environments, and the fitted magnet accepts CMSG, DMSG or EMSG switches.
