Airtac MG Stainless Steel Mini Air Cylinder MG25X75
The AirTAC Airtac MG Stainless Steel Mini Air Cylinder MG25X75 is a genuine double acting JIS-standard round-body mini air cylinder with a Ø25mm bore and 75mm stroke, 1/8" air ports and a SUS304 stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.

About the Airtac MG Stainless Steel Mini Air Cylinder MG25X75
With a 25 mm bore and 75 mm stroke, this MG delivers 245.3 N of push and 206.1 N of pull at 0.5 MPa, rising to 343.4 N at 0.7 MPa. It is a double acting JIS round-body mini cylinder: air drives the rod out and back, and a fixed anti-impact bumper pad at each stroke end softens the direction change. The barrel is SUS304 stainless steel rolled onto the covers, so the body shrugs off damp, washdown-prone spots where painted mini cylinders corrode.
The 10 mm hard-chrome plated rod runs in a riveted, compact body that follows the JIS mini-cylinder standard, so standard JIS brackets and I/Y rod knuckles bolt straight on. Because the bumper pads only decelerate, the rod will drift if air is lost - add an external rod lock or pilot check valve if you need a held position. At 0.5 MPa the push force translates to roughly 25 kgf, so plan on lifting about 12 kg vertically with a 2:1 margin. Note: no magnet is fitted, so position switches (CMSG / DMSG / EMSG) cannot be used unless you order the S code.

Where the Airtac MG Stainless Steel Mini Air Cylinder MG25X75 Is Used
Carton push-off on packing lines
The 245.3 N push at 0.5 MPa slides a filled carton off a conveyor stop plate, and the stainless barrel tolerates daily wipe-down in food-grade areas.
Small-part ejection from press dies
A 75 mm stroke clears a finished bracket from a die nest quickly at up to 800 mm/s, with the bumper pad damping the return.
Lid clamp on a lab filling station
About 12 kg of safe vertical lift capacity at a 2:1 margin holds a filling head down on small bottles without crushing them.
Is the Airtac MG Stainless Steel Mini Air Cylinder MG25X75 the Right Cylinder?
At 25 mm bore you sit mid-range in the MG family: step down to the 20 mm bore for 157 N push at 0.5 MPa, or up to 32 mm for 402.2 N when the load grows. The 75 mm stroke is well inside the 500 mm standard range, so it is a catalogue item. Match the mount to the job - LB foot, FA flange, CB clevis or SDB pivot - and remember this SKU carries no magnet, so add the S code if sensors are planned. For higher speeds or heavier loads where end-of-stroke tuning matters, the cushioned MGC in the same bore is the alternative.
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 MG25X75 FAQ
At 0.5 MPa it pushes with 245.3 N and pulls with 206.1 N; at 0.7 MPa those figures rise to 343.4 N push and 288.5 N pull. 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 as ordered - this SKU has no built-in magnet. Order the S code version (e.g. MG25X75S) and CMSG, DMSG or EMSG switches can then detect piston position along the stainless barrel.
