About the Airtac MGC Stainless Steel Mini Cylinder MGC32X125S
The AirTAC MGC32X125S is a double acting JIS-standard round-body mini cylinder with a 32 mm bore and 125 mm stroke, fitted with a variable air cushion at both stroke ends. Unlike the bumper-type MG, the cushion needles let you dial in smooth deceleration near end of travel, so this cylinder tolerates higher piston speeds and heavier moving loads without hammering the covers. At 0.5 MPa it delivers 402.2 N push and 345.6 N pull, rising to 563 N push at 0.7 MPa, with a theoretical maximum of 82 kgf at 1.0 MPa.
Construction follows the MG family recipe: a SUS304 stainless barrel with covers and stainless block riveted and rolled into place, plus a hard-chrome plated 12 mm rod (male thread M10x1.25) and a two-way piston seal that also stores lubricant. The 1/8" ports accept PT thread, and because the S code is fitted, CMSG, DMSG or EMSG magnetic switches can be mounted directly on the barrel. A practical sizing insight: the 402.2 N push force equals about 41 kgf, so a safe vertical lifting figure is roughly half of that, around 20 kg.

Where the Airtac MGC Stainless Steel Mini Cylinder MGC32X125S Is Used
High-speed pusher on a conveyor line
The variable air cushion absorbs the momentum of a fast-moving carriage at 30-800 mm/s, letting the 32 mm bore run quicker than a bumper-type MG without cover impact.
Small parts ejection from assembly fixtures
402.2 N push at 0.5 MPa is ample to kick stamped or molded parts off a nest, and the adjustable cushion stops the ejector softly so the fixture does not shake loose.
Case and carton indexing stops
As a retractable stop on a packaging conveyor, the cushioned end position handles repeated carton impacts, and the fitted magnet feeds CMSG or DMSG switches for stop-position confirmation.
Is the Airtac MGC Stainless Steel Mini Cylinder MGC32X125S the Right Cylinder?
At 32 mm bore the MGC32X125S sits mid-range in the cushioned MGC family: it gives 402.2 N push at 0.5 MPa, well above the 245.3 N of the 25 mm bore and below the 628.3 N of the 40 mm bore. If you do not need end-of-stroke deceleration, the bumper-type MG is the no-cushion alternative in this size; if you need more force with the same cushion, step up to MGC40, and for the largest cushioned bores MGC offers 50 and 63 mm. The 125 mm stroke is well inside the 500 mm maximum standard stroke for this bore, and non-standard strokes up to 800 mm are made to order. Mount with the FA flange or LB foot, add I or Y rod knuckles if the tooling needs a knuckle joint, and keep the -S magnet if position sensing via CMSG/DMSG/EMSG switches matters. At speeds up to 800 mm/s, support long strokes and avoid side loads on the rod to protect the bushing and seal life.

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 MGC32X125S FAQ
At 0.5 MPa it pushes with 402.2 N and pulls with 345.6 N; at 0.7 MPa those rise to 563 N push and 483.8 N pull. The theoretical maximum is 82 kgf at 1.0 MPa. For sizing, 402.2 N is about 41 kgf, so a conservative vertical lifting figure is roughly half of that, around 20 kg, leaving margin for friction and pressure drops.
The cushion is an adjustable air dam at both stroke ends: turn the needle valve to throttle exhaust and decelerate the piston smoothly, which is why the MGC handles higher speeds and heavier moving loads than the bumper MG. It only decelerates end of travel, however - it is not a lock or brake, and the cylinder will not hold position on air loss. For a held load, add an external rod lock or pilot-operated check valve.
