About the Airtac MG Stainless Steel Mini Air Cylinder MG25X150
With a 25 mm bore and 150 mm stroke, this MG series cylinder is a double acting JIS round-body mini cylinder: air drives the rod out and pulls it back, so no spring is involved in the return. At 0.5 MPa it delivers about 245.3 N of push force, and its SUS304 stainless barrel with a hard-chrome plated 10 mm rod shrugs off the damp, washed-down corners where painted minis corrode.
Because the footprint follows the JIS mini-cylinder standard, it drops onto standard JIS brackets and rod knuckles, which keeps spares simple. Plan your real work around roughly 147 N at 0.5 MPa rather than the full 245.3 N rating, and for vertical lifts expect about 12 kg with a 2:1 margin. Note the fixed anti-impact bumper pads only soften the stroke ends; they are not an adjustable air cushion, and the cylinder holds no position if air is lost.

Where the Airtac MG Stainless Steel Mini Air Cylinder MG25X150 Is Used
Bottling line push-off
Ejects empty PET bottles from a conveyor lane; the 245.3 N push at 0.5 MPa is ample for lightweight containers and the stainless barrel tolerates daily washdown.
Small parts press fit
Presses bearings into plastic housings on an electronics assembly bench, where the roughly 147 N usable working force at 0.5 MPa suits light interference fits.
Carton flap tucker
Folds top flaps on a carton sealing machine at 30-800 mm/s, with the fixed bumper pad absorbing the repeated end-of-stroke shock of each cycle.
Is the Airtac MG Stainless Steel Mini Air Cylinder MG25X150 the Right Cylinder?
Size against neighbours: the 20 mm bore pushes about 157 N at 0.5 MPa, while stepping up to the 32 mm bore gets you about 402.2 N, so pick the 25 mm bore when your load sits between those two. This SKU carries no magnet, so CMSG / DMSG / EMSG switches cannot be fitted; order the S code version if you need position sensing. Mount it with LB foot, FA flange, CB clevis or SDB pivot hardware, and remember it will drift when the valve is centred, so add a pilot check valve or external rod lock for held loads. At 150 mm stroke keep side loads off the 10 mm rod to avoid bending.

- ✓ 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 MG25X150 FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N; at 0.7 MPa it pushes 343.4 N and pulls 288.5 N. The theoretical maximum is 50 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.
Not on this SKU, since it has no built-in magnet. Order the MG25X150S version and you can fit CMSG, DMSG or EMSG reed or solid-state switches along the stainless barrel. The 1/8" port, JIS mounting interface and fixed anti-impact bumper pads stay the same on the magnet version.
