About the Airtac MGC Stainless Steel Mini Cylinder MGC32X125
The AirTAC MGC32X125 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; at 0.7 MPa that rises to 563 N push and 483.8 N pull, 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. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), withstands 1.5 MPa (215 psi) proof pressure, operates from -20 to +70 C, and cycles at 30-800 mm/s. Ports are 1/8". A practical sizing note: the 402.2 N push equals about 41 kgf, so a safe vertical lift figure is roughly 20 kg using the 0.6x rule of thumb. This SKU has no magnet, so position sensors (CMSG / DMSG / EMSG) require the optional -S code.

Where the Airtac MGC Stainless Steel Mini Cylinder MGC32X125 Is Used
High-cycle push-off station
Ejecting cartons or parts off a conveyor at 30-800 mm/s: the variable air cushion decelerates the piston smoothly at stroke end, so the 402.2 N push arrives fast without slamming the covers.
Small press and forming fixture
Light staking, riveting or snap-fit pressing where 563 N at 0.7 MPa is enough and the adjustable cushion prevents bounce-back on impact at the bottom of the 125 mm stroke.
Packaging gate and stopper actuation
Raising and lowering product stops or gates on packaging lines: the 345.6 N pull stroke handles return springs and gravity loads, and the cushion softens both ends of travel.
Is the Airtac MGC Stainless Steel Mini Cylinder MGC32X125 the Right Cylinder?
At 32 mm bore, the MGC32X125 sits mid-range in the cushioned MGC family: it offers 402.2 N push at 0.5 MPa, roughly 1.6x the 245.3 N of the 25 mm bore, while the 40 mm bore steps up to 628.3 N if you need more force. If your application runs slow and light and does not need end-of-stroke deceleration, the plain bumper-type MG in 32 mm bore is the no-cushion alternative within the same JIS footprint. Choose the -S option if you want magnetic position sensing with CMSG, DMSG or EMSG switches. Mounting is limited to FA flange and LB foot, with I and Y rod knuckles available for the rod side. The 125 mm stroke is well inside the 500 mm standard limit for this bore, and non-standard strokes up to 800 mm are made to order. On longer strokes, guide the load externally: the 12 mm rod is not intended to absorb side loads.

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 MGC32X125 FAQ
At 0.5 MPa it pushes with 402.2 N and pulls with 345.6 N; at 0.7 MPa the figures are 563 N push and 483.8 N pull. The theoretical maximum is 82 kgf at 1.0 MPa. For vertical lifting, a conservative rule of thumb is 0.6x the push force, so plan on roughly 20-24 kg of safe working load and use a pilot check valve or rod lock if the load must be held, since the cushion only decelerates the stroke end and is not a brake.
The cushion at both ends is adjustable: turn the needle valve to meter the exhaust air and decelerate the piston smoothly before it reaches the cover, which protects the cylinder at higher speeds and with heavier moving loads. It is not a fixed bumper pad and not a position lock. This MGC32X125 has no magnet fitted, so to mount CMSG, DMSG or EMSG reed or Hall-effect switches you must order the -S version with the built-in magnet.
