About the Airtac MGC Stainless Steel Mini Cylinder MGC63X75
The AirTAC MGC63X75 is a double acting, JIS-standard round-body mini cylinder with a 63 mm bore and 75 mm stroke, fitted with a variable air cushion at both stroke ends. Unlike the bumper-type MG, the cushion needles let you dial in end-of-stroke deceleration, so this cylinder can run at higher piston speeds and carry heavier moving loads without hammering the covers. At 0.5 MPa it delivers 1557.9 N push and 1400.9 N pull, rising to 2181 N push and 1961.2 N pull at 0.7 MPa, with a theoretical maximum of 317.7 kgf at 1.0 MPa. The 20 mm hard-chrome plated rod carries a male M18x1.5 thread, and air ports are 1/4".
Construction follows the JIS mini-cylinder pattern: covers and a SUS304 stainless block are riveted and rolled onto the stainless barrel, with no tie rods and no extruded profile. The two-way piston seal also stores lubricant, and the cylinder operates on air filtered to 40 um at 0.15 to 1.0 MPa (22 to 145 psi), proof pressure 1.5 MPa (215 psi), from -20 to +70 C at 30 to 800 mm/s. As a computed buyer insight, applying the 0.6 rule of thumb to the 0.5 MPa push force gives a safe working load of roughly 95 kg. 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 MGC63X75 Is Used
Pallet pusher on transfer carts
The 63 mm bore pushes heavy pallets or skids clear of a transfer cart at 0.5 to 0.7 MPa, with the variable air cushion stopping the 1557.9 N thrust smoothly instead of slamming the head.
Bench press and light forming
Short-stroke pressing of bearings, bushings or snap fits benefits from the 75 mm stroke, the 2181 N push at 0.7 MPa, and adjustable deceleration at the bottom of the stroke.
High-speed conveyor diverters
Kickers and diverters cycling at the upper end of the 30 to 800 mm/s speed range use the cushioned ends to avoid cover hammering, with the LB foot or FA flange matching JIS mini-cylinder brackets.
Is the Airtac MGC Stainless Steel Mini Cylinder MGC63X75 the Right Cylinder?
At 63 mm bore this is the largest MGC offered, so size up only if you genuinely need its 1557.9 N push at 0.5 MPa; the 50 mm bore MGC gives 981.3 N, and for bores 20 to 40 the bumper-type MG is the no-cushion alternative. The variable air cushion is the reason to choose MGC when piston speed or moving mass would otherwise slam the end covers. Stroke 75 mm sits well inside the 500 mm maximum standard stroke, and non-standard strokes up to 800 mm are made to order. Mount with the FA flange or LB foot, and add I or Y rod knuckles if the tooling needs a pivot; the SDB/CB pivot is not available on this series. Port thread is PT as standard, with G and NPT options. If you need position sensing, order the S magnet code, which enables CMSG, DMSG or EMSG switches; this no-S SKU carries no magnet and accepts no sensor. For strokes near the long end, guide the load externally to keep side load off 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 MGC63X75 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 a safe working load, apply about 0.6 to the 0.5 MPa push force, roughly 95 kg.
The cushion needle at each end meters exhaust air to decelerate the piston smoothly near end of stroke, so you can tune the braking for higher speeds or heavier moving loads. It is adjustable, not a fixed pad, and it only decelerates; it is not a lock or brake. To hold position on air loss, fit an external rod lock or pilot check valve.
