About the Airtac MG Stainless Steel Mini Air Cylinder MG25X225
With a 25 mm bore and a 225 mm stroke, this MG series cylinder is a double acting JIS round-body mini cylinder: air drives the rod out and pulls it back, delivering 245.3 N push and 206.1 N pull at 0.5 MPa (343.4 N / 288.5 N at 0.7 MPa). The SUS304 stainless barrel is riveted onto the covers with a hard-chrome plated 10 mm rod, so the body shrugs off damp, washdown-prone spots that quickly ruin painted-steel minis.
Because the footprint follows the JIS mini-cylinder standard, it drops onto standard brackets and I / Y rod knuckles you may already stock. In practice, plan on roughly 147 N of usable push at 0.5 MPa, which lifts about 12 kg vertically with a 2:1 margin - enough for small clamps, gates and part pushers. A fixed anti-impact bumper pad softens each stroke end; it decelerates only and is not an adjustable air cushion.

Where the Airtac MG Stainless Steel Mini Air Cylinder MG25X225 Is Used
Bottling line gate pusher
The 245.3 N push at 0.5 MPa slides small crates or bottles sideways on a conveyor, while the stainless barrel copes with frequent washdown.
Packaging machine ejector
A 225 mm stroke rejects off-spec packs from a cartoner without redesigning the frame, thanks to the standard JIS mounting interface.
Small parts press-fit station
About 147 N of practical working force seats bushings or labels in light assembly jigs, with the bumper pad softening each cycle end.
Is the Airtac MG Stainless Steel Mini Air Cylinder MG25X225 the Right Cylinder?
Size by force: the smaller MG20X225 gives 157.0 N push at 0.5 MPa, while stepping up to MG32X225 raises that to 402.2 N - pick the 25 mm bore when your load sits between those figures. Note that a plain MG drifts if air pressure is lost or the valve centres, so fit an external rod lock or a pilot check valve wherever the load must stay put. This SKU carries no magnet, so CMSG / DMSG / EMSG switches cannot be fitted - order the -S version if you need position sensing. At 225 mm stroke the rod is well extended, so keep side loads off the rod or guide them externally.
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 MG25X225 FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N; at 0.7 MPa that rises to 343.4 N push and 288.5 N pull, with a theoretical maximum of 50 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, temperature -20 to +70 C, and the port is 1/8" on this 25 mm bore.
No - this MG25X225 has no built-in magnet, so CMSG, DMSG or EMSG switches cannot detect the piston. Order the magnet-equipped -S version (for example MG25X225S) if you need end-of-stroke sensing.
