About the Airtac MG Stainless Steel Mini Air Cylinder MG32X250S
With a 32 mm bore and a 250 mm stroke, this MG series cylinder delivers double acting power - about 402.2 N push and 345.6 N pull at 0.5 MPa, rising to 563 N at 0.7 MPa - inside a compact JIS round body. The riveted SUS304 stainless barrel with a hard-chrome plated 12 mm rod shrugs off washdown and damp shop air far better than painted-steel minis, and the 1/8" port keeps plumbing simple across all four MG bores.
The S in the code means 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. At the stroke ends, fixed anti-impact bumper pads soften the direction change - they decelerate the piston but are not an adjustable air cushion. As a JIS-standard mini cylinder, its mounting footprint accepts standard JIS brackets and rod knuckles, which makes spare-part swaps painless. For planning: at 0.5 MPa expect roughly 240 N of usable push, enough to lift about 24 kg vertically with a 2:1 margin.

Where the Airtac MG Stainless Steel Mini Air Cylinder MG32X250S Is Used
Bottling line pusher
The 402.2 N push at 0.5 MPa nudges rows of 500 ml bottles off a conveyor into a lane, while the stainless barrel handles daily washdown without paint flaking into the product zone.
Pick-and-place verification
With the built-in magnet driving a CMSG switch, a small assembly cell confirms full clamp on plastic housings at each 250 mm stroke, cutting misloaded-part escapes.
Carton flap tucker
Mounted clevis-style on a case packer, the cylinder folds bottom flaps on shipping cartons; the bumper pad quiets the high-cycle direction change at up to 800 mm/s.
Is the Airtac MG Stainless Steel Mini Air Cylinder MG32X250S the Right Cylinder?
At 402.2 N push (0.5 MPa) this bore sits between the 25 mm MG (245.3 N) and the 40 mm MG (628.3 N) - pick the 32 if your load lands in the 200-350 N working band, and step up only if you need the extra margin. The 250 mm stroke is well inside the 500 mm standard range for this bore, so no made-to-order lead time applies. On a 250 mm stroke keep the rod side-loaded: with a 12 mm rod, guide the payload externally rather than letting the rod carry lateral force. Mount with LB foot, FA flange, CB clevis or SDB pivot, and remember a plain MG drifts when air is removed - add a pilot check valve or external rod lock if the load must stay put.
Quick checklist

- ✓ 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 MG32X250S 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. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, and speed runs 30-800 mm/s.
Yes - the S in MG32X250S means the piston carries a magnet, so AirTAC CMSG, DMSG or EMSG reed/electronic switches mount directly on the 32 mm barrel for end-of-stroke detection. Note the fixed bumper pads only soften the stroke end; they do not hold or brake a load if air pressure is lost.
