About the Airtac MSG Stainless Steel Mini Air Cylinder MSG25X75S
The MSG25X75S is a single acting, push-type JIS round-body mini cylinder: compressed air extends the 10 mm rod through a 75 mm stroke, and an internal return spring retracts it the moment air is released. Because air is only needed on the work stroke, one air line and one valve port drive the whole cycle, which trims air use and simplifies piping for one-way clamp, eject and press duties. The 25 mm bore delivers about 171.8 N push at 0.5 MPa and 269.9 N at 0.7 MPa, figures already net of the return spring, so a realistic working load is roughly 100 N (about 10 kg) at 0.5 MPa, or a safe vertical lift of around 8 kg.
Construction suits damp and washdown-adjacent lines: a SUS304 stainless barrel with a hard-chrome (20 um) carbon-steel rod, riveted covers, a two-way lubricant-storing piston seal and a fixed anti-impact bumper pad that softens each stroke end. The magnet fitted under the S code lets CMSG, DMSG or EMSG switches report rod position, and the JIS footprint drops straight into standard JIS mini brackets and I/Y knuckles. Mounting options include LB foot, FA flange, CB clevis and SDB pivot, with a 1/8" port on every bore. Operating pressure is 0.2-1.0 MPa (28-145 psi) and speed runs 50-800 mm/s.

Where the Airtac MSG Stainless Steel Mini Air Cylinder MSG25X75S Is Used
Spring-return clamping
Air pushes a clamp arm onto a fixture with about 171.8 N at 0.5 MPa; releasing the valve lets the spring back the arm off, so a jam or power cut leaves the part free.
Part ejection from a chute or die
One valve port fires the rod to knock a finished part off a conveyor stop or out of a nest; the spring retracts automatically for the next cycle at 50-800 mm/s.
Lid press and tamping station
The 25 mm bore presses caps or plugs home with up to 269.9 N at 0.7 MPa, while the fixed bumper pad softens the end of each press stroke.
Is the Airtac MSG Stainless Steel Mini Air Cylinder MSG25X75S the Right Cylinder?
Choose the MSG25X75S when a one-way push of roughly 100 N working load (about 171.8 N at 0.5 MPa, 269.9 N at 0.7 MPa) over 75 mm is enough and a spring return is acceptable. Bore 25 sits mid-range in the MSG family: bore 20 gives the smallest package, bore 40 the strongest push at 439.6 N at 0.5 MPa. Note the 0.2 MPa (28 psi) minimum working pressure set by the spring, and that on air loss the spring simply retracts the rod to rest, so it does not hold a load in place. Spring-return travel caps the standard stroke at 150 mm for this bore; if you need a two-directional stroke or a longer reach, step up to the double-acting MG. Order LB, FA, CB or SDB mounting, add I or Y knuckles as needed, and keep the S suffix for CMSG/DMSG/EMSG sensing. Thread is PT (G and NPT available).
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 0.2 – 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 MSG Stainless Steel Mini Air Cylinder MSG25X75S FAQ
The 25 mm bore gives 171.8 N push at 0.5 MPa and 269.9 N at 0.7 MPa, already net of the return spring. Operating pressure is 0.2-1.0 MPa (28-145 psi) with a 0.2 MPa minimum set by the spring, proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C, speed 50-800 mm/s, and a 1/8" port.
Air extends the rod; when air is released the internal spring retracts it to rest, so only one air line and one valve port are needed. On air loss the rod returns but nothing is locked or held. The S suffix means a magnet is fitted, so CMSG, DMSG or EMSG switches can sense position - the double-acting MG instead powers both strokes with air.
