About the Airtac MGC Stainless Steel Mini Cylinder MGC63X500S
The AirTAC MGC63X500S is a double acting, JIS-standard round-body mini cylinder with a 63 mm bore and a 500 mm stroke, and it is the largest bore in the MGC cushioned range. Unlike the bumper-type MG, this model carries a variable air cushion at both stroke ends: turn the cushion needle to dial in smooth deceleration of the piston near end of travel, so the cylinder tolerates higher piston speeds (30-800 mm/s) and heavier moving loads without hammering the covers. At 0.5 MPa it delivers a push force of 1557.9 N and a pull force of 1400.9 N, rising to 2181 N push at 0.7 MPa, with a theoretical maximum of 317.7 kgf at 1.0 MPa.
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 um) 20 mm carbon-steel rod with an M18x1.5 male thread. The two-way piston seal also stores lubricant for long service life. Air supply should be filtered to 40 um; operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure and a -20 to +70 C temperature range. The fitted magnet (S 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 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 MGC63X500S Is Used
High-speed pusher on packaging lines
The variable air cushion absorbs the energy of a fast-approaching piston, letting the 63 mm bore push cartons or trays at up to 800 mm/s without slamming the covers, while the magnet feeds CMSG switches to the PLC.
Clamping and press-fit fixtures
With 1557.9 N push at 0.5 MPa (2181 N at 0.7 MPa), this cylinder seats parts or clamps workpieces in machining and assembly fixtures, and the adjustable cushion prevents bounce-back at the end of the stroke.
Conveyor divert and gate actuation
The long 500 mm stroke and cushioned ends suit diverters, lifters and stopper gates on conveyor systems, where the SUS304 stainless barrel and hard-chrome rod resist washdown-side wear and corrosion.
Is the Airtac MGC Stainless Steel Mini Cylinder MGC63X500S the Right Cylinder?
At 63 mm bore this is the biggest force in the MGC range: 1557.9 N push at 0.5 MPa, roughly 158.8 kgf, which gives a practical safe working load of about 95 kg using the 0.6 rule of thumb (about 79 kg for a vertical lift after halving). There is no larger MGC bore, so if you need more force step up to a larger series; if you need less, the 50 mm MGC offers 981.3 N push at 0.5 MPa, and for 20-40 mm bores the bumper-type MG is the no-cushion alternative. Choose this model when your cycle runs fast or carries a heavy moving mass that would hammer an uncushioned mini cylinder. The 500 mm stroke is the maximum standard stroke for this bore, so no made-to-order length is needed. Mount with the FA flange or LB foot and add I or Y rod knuckles where the tooling needs a pivot; the -S magnet lets you fit CMSG, DMSG or EMSG switches for end-of-stroke detection. On a 500 mm stroke, keep rod side-loading low and guide the load externally to protect the 20 mm hard-chrome 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 MGC63X500S FAQ
At 0.5 MPa the push force is 1557.9 N and the pull force is 1400.9 N. At 0.7 MPa it reaches 2181 N push and 1961.2 N pull, and the theoretical maximum is 317.7 kgf at 1.0 MPa. As a rule of thumb, treat about 0.6 of the 0.5 MPa push force (roughly 95 kg) as a safe working load, or about 79 kg for vertical lifting.
The cushion needle at each end meters the exhaust air so the piston decelerates smoothly just before end of stroke; adjust it to match your speed and moving mass. The cushion only decelerates travel, it is not a lock, brake or position holder, and the cylinder will not hold position if air is lost. For a held load, add an external rod lock or pilot check valve.
