Airtac MG Stainless Steel Mini Air Cylinder MG32X400
The AirTAC Airtac MG Stainless Steel Mini Air Cylinder MG32X400 is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 400mm stroke, 1/8" air ports and a SUS304 stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.

About the Airtac MG Stainless Steel Mini Air Cylinder MG32X400
With a 32 mm bore pushing 402.2 N at 0.5 MPa over a 400 mm stroke, this MG series cylinder is a double acting round-body unit built to the JIS mini-cylinder standard. The SUS304 stainless barrel and hard-chrome plated rod (12 mm, M10x1.25 male thread) shrug off damp washdown and outdoor conditions that quickly ruin painted-steel minis, and the riveted covers keep the body compact and light.
Because the footprint follows JIS, standard mini-cylinder brackets and rod knuckles drop straight on, so spares stay interchangeable across your machine park. The fixed anti-impact pad at each stroke end softens direction changes, but it is a decelerator only, not an adjustable cushion and not a lock: with no magnet fitted (no S code), CMSG / DMSG / EMSG switches cannot be mounted, and the rod will drift if air is lost. In practice, plan on roughly 241 N of usable work at 0.5 MPa, which lifts about 20 kg vertically with a sensible 2:1 margin.

Where the Airtac MG Stainless Steel Mini Air Cylinder MG32X400 Is Used
Bottling line pusher
The 402.2 N push at 0.5 MPa ejects cartons or trays off a conveyor across the full 400 mm stroke, while the stainless barrel survives frequent washdown.
Small press and staking fixture
About 241 N of usable work force at 0.5 MPa suits light staking, riveting or crimping jigs on electronics and small hardware assemblies.
Lab and sample handling gate
The 400 mm reach opens and closes gates or sample drawers in test rigs, with the fixed bumper pads softening every direction change.
Is the Airtac MG Stainless Steel Mini Air Cylinder MG32X400 the Right Cylinder?
Size by force, not bore alone: at 0.5 MPa the 25 mm MG pushes only 245.3 N, so step up to this 32 mm bore when your load needs more than about 240 N of real work; the 40 mm bore (628.3 N push) is the next step if you want margin for friction or pressure dips. Over a 400 mm stroke, watch side loads: with a 12 mm rod, guide the load externally rather than letting the rod carry bending moments. Mount with LB foot, FA flange, CB clevis or SDB pivot (with CB), and add I or Y knuckles on the rod. If you need position sensing, order the -S magnet version, since this SKU without S accepts no sensor. For high speeds or heavy loads needing adjustable cushioning, move to the MGC series instead.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting (LB / FA / CB / SDB) & knuckle
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/impact settings and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MG Stainless Steel Mini Air Cylinder MG32X400 FAQ
At 0.5 MPa it pushes 402.2 N and pulls 345.6 N; at 0.7 MPa, 563 N push and 483.8 N pull. Theoretical maximum is 82 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-800 mm/s, port 1/8", rod 12 mm with M10x1.25 male thread.
Not on this SKU: it has no built-in magnet. Order the -S version (for example MG32X400S) to enable CMSG, DMSG or EMSG reed/hall switches. Also note the fixed bumper pads only soften stroke-end impact; they do not hold the rod in place, so use an external rod lock or pilot check valve if the load must stay put when air is lost.
