About the Airtac MSG Stainless Steel Mini Air Cylinder MSG25X75
The MSG25X75 is a single acting, PUSH type JIS round-body mini cylinder: compressed air extends the 10 mm rod over a 75 mm stroke, and an internal return spring retracts it the moment air is released. With a 25 mm bore it delivers about 171.8 N of push at 0.5 MPa and 269.9 N at 0.7 MPa, figures already net of the spring, and it runs from just 0.2 MPa (28-145 psi working range, 1.5 MPa / 215 psi proof). Because air is only supplied on the work stroke, the circuit needs a single air line and one valve port, which saves air and simplifies plumbing for one-way clamp, eject or press duties.
Construction suits demanding export machinery: a SUS304 stainless barrel with a hard-chromed carbon-steel rod resists damp and washdown environments, riveted covers keep the round body compact, and a fixed anti-impact bumper pad softens each stroke end. The JIS-standard footprint drops straight into standard JIS mini brackets and I or Y rod knuckles. As a practical sizing note, apply roughly 0.6 of the push force as a working load (about 103 N at 0.5 MPa), which corresponds to a safe vertical lift of roughly 8 kg. The 75 mm stroke sits well inside the 150 mm maximum standard stroke for this bore; for longer or two-directional travel, step up to the double-acting MG series.

Where the Airtac MSG Stainless Steel Mini Air Cylinder MSG25X75 Is Used
Spring-return clamping
Air pushes the rod to clamp a jig or workpiece; releasing the valve lets the spring retract the clamp automatically, so a lost air signal always opens the fixture.
Part ejection
At 171.8 N push at 0.5 MPa the 25 mm bore ejects stamped or molded parts off a chute or nest, with the spring pulling the ejector back for the next cycle.
Small lid press
A light press-fit or lid-closing station uses the 75 mm work stroke and about 103 N of usable working force, while the spring return clears the part without a second valve port.
Is the Airtac MSG Stainless Steel Mini Air Cylinder MSG25X75 the Right Cylinder?
Choose the MSG25X75 when a one-way 75 mm stroke needs about 171.8 N of push at 0.5 MPa (269.9 N at 0.7 MPa) and a spring return is acceptable. It is the mid-small option in the MSG range: bore 20 gives the least force, bore 40 the most (439.6 N at 0.5 MPa), so size up if your load needs more margin. Remember the spring sets a 0.2 MPa minimum working pressure and retracts the rod whenever air is released, so the cylinder cannot hold a load in position. Standard strokes for this bore stop at 150 mm; for longer travel or powered return in both directions, use the double-acting MG. Mounting options are LB foot, FA flange, CB clevis and SDB pivot, plus I and Y rod knuckles; add the S code to fit CMSG, DMSG or EMSG switches. Ports are 1/8" on every MSG bore.

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 MSG25X75 FAQ
The 25 mm bore gives 171.8 N of 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), proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C, and speed 50-800 mm/s. Air should be filtered to 40 um, and the port is 1/8".
Air extends the rod; when pressure is released the internal spring retracts it to the rest position, so only one air line and one valve port are needed. On air loss the rod returns, so the cylinder does not hold a load, and the fixed bumper pad only softens the stroke end. For position sensing, order the -S version to mount CMSG, DMSG or EMSG switches; without the magnet no sensor can be fitted. If you need powered return, choose the double-acting MG instead.
