About the Airtac MTG Stainless Steel Mini Cylinder MTG32X25S
The MTG32X25S is a JIS-standard round-body mini cylinder built for single acting pull duty: an internal spring holds the rod out at rest, and compressed air retracts (pulls) it on the work stroke. With a 32 mm bore and 25 mm stroke it delivers about 224.8 N of net pull at 0.5 MPa and 363 N at 0.7 MPa, already after the spring, so the figures you see are what reaches the load. One air line is all it needs, which keeps plumbing simple on machines where the motion is a one-way draw, retract, close or tension move.
The barrel is SUS304 stainless with a hard-chrome (20 um) carbon-steel rod, so the cylinder tolerates damp and washdown environments, and the riveted round-body construction follows the JIS mini footprint. Because the spring return caps the standard stroke at 150 mm, this 25 mm version suits short, snappy pull motions at 50-800 mm/s. A practical sizing note: at 0.5 MPa the pull equals roughly 22.9 kgf, so for a vertical lift keep the load to about 13 kg (60 percent of the force). The fitted magnet (-S code) allows CMSG, DMSG or EMSG switches for end-of-stroke signalling.

Where the Airtac MTG Stainless Steel Mini Cylinder MTG32X25S Is Used
Retract a locking pin
Air pulls the pin out of a fixture or die on command; if air is lost, the spring pushes the pin back to its extended, locked position automatically.
Tension a belt or chain
The spring keeps the idler pushed out to maintain belt tension, and air draws it in when the drive must be released for maintenance.
Close a gate or shutter
A short 25 mm pull closes a chute gate or guard shutter on a packaging line, with the magnet and a CMSG switch confirming the closed position.
Is the Airtac MTG Stainless Steel Mini Cylinder MTG32X25S the Right Cylinder?
Choose the MTG32X25S when your working motion is a one-way pull of 25 mm and the force class fits: 224.8 N net pull at 0.5 MPa, 363 N at 0.7 MPa. If you need more pull, step up to the MTG40 (339.1 N at 0.5 MPa); for lighter duty the MTG25 gives 132.6 N. Remember the direction of operation: the spring extends the rod and air retracts it, and the minimum working pressure is 0.2 MPa (28 psi) because the spring must be overcome on the pull stroke. If you need two-way powered travel or a stroke beyond the 150 mm spring-return limit, move to the double-acting MG series instead. Mounting options are LB foot, FA flange, CB clevis and SDB pivot, plus I and Y rod knuckles; the S in this model code means the magnet is already fitted for CMSG/DMSG/EMSG switches. Port is 1/8" on every MTG 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 MTG Stainless Steel Mini Cylinder MTG32X25S FAQ
Net pull (already after the spring) is 224.8 N at 0.5 MPa and 363 N at 0.7 MPa. Operating pressure is 0.2-1.0 MPa (28-145 psi), proof pressure is 1.5 MPa (215 psi), fluid is air filtered to 40 um, temperature range is -20 to +70 C, and speed is 50-800 mm/s. The port is 1/8" and the male rod thread is M10x1.25.
In the MTG the spring extends the rod at rest and air retracts (pulls) it on the work stroke, so on air loss the rod returns to its extended position. The MSG is the opposite single acting type (air pushes, spring retracts), and the MG is double acting with air on both sides for powered two-way travel and strokes beyond the 150 mm spring-return limit. This S model carries a magnet for CMSG/DMSG/EMSG switches; the bumper pad softens stroke ends but is not a lock or brake.
