About the Airtac MG Stainless Steel Mini Air Cylinder MG32X400S
With a 32 mm bore and a long 400 mm stroke, this double acting MG from AirTAC delivers 402.2 N of push and 345.6 N of pull at 0.5 MPa, rising to 563 N at 0.7 MPa. The JIS-standard round body is built from a SUS304 stainless barrel with a hard-chrome plated 12 mm rod, and the covers are riveted onto the tube rather than tie-rod clamped, so the cylinder stays compact and corrosion-resistant in damp or washdown-prone machines. A fixed anti-impact pad at each end softens the direction change; it decelerates the stroke end only and is not an adjustable air cushion.
Because the S code is in the model, a magnet is built into the piston, so CMSG, DMSG or EMSG switches can be clipped on for end-of-stroke signalling without any rework. For sizing in practice, treat roughly 240 N (about 24 kg of vertical lift equivalent) as the usable working force at 0.5 MPa instead of the full 402.2 N rating, which leaves margin for friction and pressure drop. Ports are 1/8" on every MG bore, and the standard operating envelope is 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s.

Where the Airtac MG Stainless Steel Mini Air Cylinder MG32X400S Is Used
Bottle rejection pusher
A 400 mm reach lets one cylinder sweep rejected bottles or cartons across a wide conveyor lane, with 402.2 N of push at 0.5 MPa easily overcoming line friction.
Position feedback on a gate
The built-in magnet and CMSG switches report open and closed positions on a stainless machine guard gate, useful in food or washdown areas where a painted cylinder would corrode.
Carton hold-down on a case packer
The 32 mm bore presses carton flaps during gluing; plan on about 240 N of usable force at 0.5 MPa and note the load will drift if air is lost, so add a check valve to hold it.
Is the Airtac MG Stainless Steel Mini Air Cylinder MG32X400S the Right Cylinder?
At 0.5 MPa this bore sits between the 25 mm MG (245.3 N push) and the 40 mm MG (628.3 N push), so pick the 32 mm when your load needs roughly 300-400 N and the 25 mm feels marginal. The 400 mm stroke is within the 500 mm standard range for this bore, but a long extension like this is more exposed to side load: keep the rod aligned, guide the load externally where possible, and consider a clevis (CB) or pivot bracket (SDB) mount if the pin axis can move. Remember the MG will drift if air is lost or the valve centres, so fit an external rod lock or a pilot check valve when the load must stay put. If your cycle is fast or the load is heavy, the cushioned MGC in the same bore family is the alternative to consider.

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 MG32X400S FAQ
At 0.5 MPa it pushes with 402.2 N and pulls with 345.6 N. At 0.7 MPa those figures rise to 563 N push and 483.8 N pull. The theoretical maximum is 82 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, speed is 30-800 mm/s, and the port is 1/8".
The S means a piston magnet is factory-fitted, so CMSG, DMSG or EMSG reed or Hall-effect switches can be snapped onto the stainless barrel for end-of-stroke detection. Without the S code there is no magnet and no sensor option. Note the fixed bumper pads only soften the stroke end; they do not lock or hold the rod, and the JIS-standard mounting accepts standard mini-cylinder brackets and rod knuckles (I and Y).
