About the Airtac MG Stainless Steel Mini Air Cylinder MG32X300S
With a 32 mm bore and a 300 mm stroke, this MG series cylinder is a double acting, JIS-standard round-body mini cylinder built around a riveted SUS304 stainless barrel and a hard-chrome plated 12 mm rod. The fixed anti-impact bumper pads at each stroke end soften the direction change - they decelerate the piston, they are not an adjustable air cushion. Because the footprint follows the JIS mini-cylinder standard, it drops onto standard JIS brackets and rod knuckles, which makes spares and redesigns painless.
At 0.5 MPa it pushes about 402 N and pulls about 346 N; at 0.7 MPa those figures rise to roughly 563 N and 484 N, with a theoretical maximum of 82 kgf at 1.0 MPa. In practice, plan on about 240 N of real work at 0.5 MPa, which means it lifts roughly 24 kg vertically with a sensible margin. The fitted magnet works with CMSG, DMSG or EMSG switches, and the stainless body shrugs off the damp and washdown conditions that defeat painted mini cylinders.

Where the Airtac MG Stainless Steel Mini Air Cylinder MG32X300S Is Used
Bottling line pusher
The 402 N push at 0.5 MPa deflects empty PET bottles off a conveyor lane, and the SUS304 barrel handles repeated washdown in a wet bottling environment.
Small parts lift station
Lifts about 24 kg vertically at 0.5 MPa - enough for a loaded fixture tray rising 300 mm on an assembly cell indexing table.
Position-verified clamp
The built-in magnet feeds CMSG or DMSG switch signals to the PLC, confirming full clamp and release on a machining fixture between cycles.
Is the Airtac MG Stainless Steel Mini Air Cylinder MG32X300S the Right Cylinder?
At 32 mm bore you sit mid-range: the 25 mm MG delivers about 245 N push at 0.5 MPa, while stepping up to 40 mm gets you about 628 N - so pick 32 mm when your load sits between roughly 150 and 350 N. The 300 mm stroke is well inside the 500 mm standard range, so no made-to-order lead time applies. With a long 300 mm stroke, keep side loads off the 12 mm rod or guide them externally to avoid rod bending. Mount it LB foot, FA flange, CB clevis or SDB pivot, and remember this cylinder does not hold position when air is lost - the piston drifts, so add an external rod lock or a pilot check valve 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 MG32X300S FAQ
At 0.5 MPa it pushes 402.2 N and pulls 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. Operating pressure spans 0.15-1.0 MPa (22-145 psi), speed runs 30-800 mm/s, and the port is 1/8".
This SKU already carries the -S magnet, so CMSG, DMSG or EMSG reed or Hall-effect switches mount directly on the barrel to signal end-of-stroke. A non-S MG cannot take these switches. Also note the bumper pads only soften the stroke end - they never lock or hold a load when air is lost.
