Airtac MG Stainless Steel Mini Air Cylinder MG32X40
The AirTAC Airtac MG Stainless Steel Mini Air Cylinder MG32X40 is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 40mm 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 MG32X40
With a 32 mm bore and a short 40 mm stroke, this MG delivers about 402.2 N of push and 345.6 N of pull at 0.5 MPa, rising to 563 N at 0.7 MPa. It is a double acting, JIS-standard round-body mini cylinder: a SUS304 stainless barrel rolled onto the covers with a hard-chrome plated rod, giving corrosion resistance that painted-steel minis lose in damp or washdown corners. The 12 mm rod carries an M10x1.25 male thread and every port is 1/8".
For sizing, treat roughly 240 N (about 24 kg) as the realistic working push at 0.5 MPa, which vertically lifts around 20 kg with a 2:1 margin. The fixed anti-impact bumper pads soften the direction change at each stroke end, but they are not an adjustable air cushion, and the piston will drift if air is lost, so use an external check valve or rod lock where a load must be held.

Where the Airtac MG Stainless Steel Mini Air Cylinder MG32X40 Is Used
Small press fixture
The 402.2 N push at 0.5 MPa suits a compact bench fixture that clinches or seats small aluminium brackets in short cycles.
Carton push-off
On a packaging line, the 40 mm stroke kicks lightweight cartons or trays off a conveyor lane at up to 800 mm/s.
Lab gate actuator
The stainless SUS304 barrel and 1/8" ports fit a compact gate or shutter on lab and washdown equipment where painted bodies corrode.
Is the Airtac MG Stainless Steel Mini Air Cylinder MG32X40 the Right Cylinder?
At 0.5 MPa the 32 mm bore pushes 402.2 N; the 25 mm MG below it manages 245.3 N and the 40 mm bore reaches 628.3 N, so pick 32 when 245 N is marginal but 628 N is overkill. This SKU has no S magnet, so CMSG / DMSG / EMSG switches cannot be fitted; order an S-coded model if you need position sensing. Mount it on LB feet, an FA flange, a CB clevis or an SDB pivot, with I or Y rod knuckles on the M10x1.25 thread. The 40 mm stroke is well inside the 500 mm standard range, and the short stroke keeps side-load on the rod low.

- ✓ 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 MG32X40 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. The 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, and the port is 1/8" on all four ports.
No. This SKU has no built-in magnet, so CMSG, DMSG or EMSG switches cannot detect the piston. Order the S version (for example MG32X40S) to enable sensing, and note the fixed bumper pads only soften the stroke end; they do not hold or brake a load.
