About the Airtac MGC Stainless Steel Mini Cylinder MGC63X800
The AirTAC MGC63X800 is a double acting, JIS-standard round-body mini cylinder with a 63 mm bore and an 800 mm stroke, built with a variable air cushion at both stroke ends. Because the cushion needle is adjustable, you can dial in the deceleration profile to match the load, so this cylinder handles higher piston speeds and heavier moving masses than the fixed-bumper 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 a rule of thumb, keep vertical lifting loads to about 0.6 of the push force, roughly 95 kg at 0.5 MPa, to preserve margin for friction and acceleration.
Construction follows the MG family recipe: a SUS304 stainless barrel with covers and stainless block riveted and rolled onto it, plus a hard-chrome plated 20 mm rod (20 um plating) with an M18x1.5 male thread and 1/4" ports. The two-way piston seal also stores lubricant for long service life. Operating pressure is 0.15 to 1.0 MPa (22 to 145 psi), proof pressure 1.5 MPa (215 psi), temperature range -20 to +70 C, and speed range 30 to 800 mm/s. Note that the 800 mm stroke exceeds the 500 mm maximum standard stroke for this bore, so it is supplied as a made-to-order item. The cushion decelerates the piston near end of travel only; it is not a lock, 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 MGC63X800 Is Used
Heavy pallet pusher on conveyor ends
The 1557.9 N push at 0.5 MPa and adjustable cushion let this cylinder index or divert heavy pallets at speed without the covers taking a hammering at stroke end.
Vertical lift-and-lower fixture clamp
With roughly 95 kg safe vertical working load at 0.5 MPa, the cushioned deceleration protects the tooling on the down stroke; add a pilot check valve if the load must hold on air loss.
Fast ejector on packaging machinery
Running near the 800 mm/s top speed, the variable air cushion at both ends absorbs the kinetic energy of the moving mass, extending seal and cover life over the bumper MG.
Is the Airtac MGC Stainless Steel Mini Cylinder MGC63X800 the Right Cylinder?
At 63 mm bore this is the largest MGC offered, so size up only if you need more than 1557.9 N push at 0.5 MPa (2181 N at 0.7 MPa); there is no larger bore in the family. If your bore needs sit between 20 and 40 mm and you do not need end-of-stroke deceleration, the bumper-type MG is the lower-cost alternative, but only MGC (and MGCD) exist in 50 and 63 mm. The variable air cushion is the main reason to choose this over a plain mini cylinder: adjust the needle so fast, heavy loads glide to a stop instead of slamming. Mount with the FA flange or LB foot, and add I or Y rod knuckles if the tooling needs a swivel joint. Order the -S magnet option if you want position sensing with CMSG, DMSG or EMSG switches; without the magnet no sensor can be mounted. With an 800 mm stroke, keep rod side loading low and use guides or knuckles to protect the long hard-chrome rod and the cushion seals. Ports are 1/4" with PT thread standard (G or NPT on request).

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 MGC63X800 FAQ
At 0.5 MPa it produces 1557.9 N push and 1400.9 N pull; at 0.7 MPa, 2181 N push and 1961.2 N pull. The theoretical maximum is 317.7 kgf at 1.0 MPa. For vertical lifting, a practical rule is about 0.6 of the push force, roughly 95 kg at 0.5 MPa, leaving margin for friction and acceleration.
The maximum standard stroke for MGC bore 63 is 500 mm, so 800 mm is a non-standard, made-to-order stroke. The cylinder has a variable air cushion at both ends: turn the cushion needle to throttle exhaust air and decelerate the piston smoothly near end of travel. It is adjustable, not a fixed pad, and it does not lock or hold the load; use an external rod lock or pilot check valve for held loads.
