The AirTAC Airtac MSG Stainless Steel Mini Air Cylinder MSG32X75S is a genuine single acting, push (spring return) JIS-standard round-body mini air cylinder with a Ø32mm 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.
The MSG32X75S is a single acting, push type JIS round-body mini cylinder with a 32 mm bore and 75 mm stroke: compressed air extends the rod, and an internal return spring retracts it when air is released. Because air is only supplied on the work stroke, the circuit needs just one air line and one valve port, which saves air and simplifies plumbing for one-way clamp, eject and press duties. With the magnet fitted (the S in the code), CMSG, DMSG or EMSG switches can be mounted to signal end-of-stroke positions. Push output is already net of the spring: about 281.3 N at 0.5 MPa and 442.1 N at 0.7 MPa. A practical rule of thumb is to load this cylinder to roughly 0.6 of its push force, so about 168 N, or a vertical lift of around 14 kg at 0.5 MPa.
Construction is a riveted round body with a SUS304 stainless barrel and a hard-chrome plated carbon-steel rod, so it stands up to damp and washdown environments. The JIS standard footprint drops into standard JIS mini brackets and I or Y rod knuckles. Ports are 1/8" on every MSG bore, operating pressure is 0.2-1.0 MPa (28-145 psi) with a 1.5 MPa (215 psi) proof pressure, temperature range is -20 to +70 C, and speed is 50-800 mm/s. Fixed anti-impact bumper pads soften the stroke ends. Spring-return travel caps the standard stroke at 150 mm for this bore; for a two-directional or longer stroke, step up to the double-acting MG.

Clamps a jig or workpiece with about 281.3 N at 0.5 MPa; if air is lost, the spring releases the clamp automatically for fail-safe unloading.
A 75 mm push stroke knocks finished parts off a nest or out of a chute, then the spring retracts the rod with no second valve port needed.
Presses caps, lids or light fittings with up to 442.1 N at 0.7 MPa, well matched to the roughly 168 N safe working load for consistent results.
Choose the MSG32X75S when a one-way push of roughly 168 N (0.6 x the 281.3 N push at 0.5 MPa) or a vertical lift of about 14 kg is enough, and a 75 mm stroke fits the job. Bore 32 sits in the middle of the MSG range: bore 20 gives about 109.9 N and bore 25 about 171.8 N at 0.5 MPa for lighter clamping, while bore 40 reaches 439.6 N for heavier presses. Remember the spring sets a 0.2 MPa minimum working pressure, and on air loss the spring returns the rod to its retracted rest position; the bumper pad softens the stroke end but is not a lock or brake. Standard strokes for this bore run up to 150 mm; for a two-way stroke or longer travel, use the double-acting MG. Mounting options are LB foot, FA flange, CB clevis and SDB pivot, plus I and Y knuckles, and the fitted magnet accepts CMSG, DMSG or EMSG switches.
Quick checklist
Push output is net of the return spring: 281.3 N at 0.5 MPa and 442.1 N at 0.7 MPa. Operating pressure is 0.2-1.0 MPa (28-145 psi), with the 0.2 MPa floor set by the spring, proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C, and speed 50-800 mm/s. Air must be filtered to 40 um, and the port is 1/8".
Air extends the rod through one 1/8" port; when air is released the internal spring retracts it to the rest position, so the cylinder does not hold a load on air loss. The fixed bumper pad only softens the stroke end. The S in MSG32X75S means a magnet is fitted, so CMSG, DMSG or EMSG switches can be mounted; the double-acting MG instead powers both strokes with air.
