About the Airtac MTG Stainless Steel Mini Cylinder MTG25X100S
The AirTAC MTG25X100S is a single acting, spring-return JIS round-body mini cylinder with a 25 mm bore and 100 mm stroke: the internal spring holds the rod out at rest, and compressed air retracts (pulls) it on the work stroke. Because air is only used on the pull stroke, one air line is all you need - an economical fit for one-way draw, retract, close or tension motions. Net pull output is already after the spring: about 132.6 N at 0.5 MPa and 215 N at 0.7 MPa, with a 0.2 MPa minimum working pressure and a 50-800 mm/s speed range.
Construction follows the JIS mini-cylinder footprint with a riveted SUS304 stainless barrel and a hard-chrome plated rod, so it stands up to damp and washdown environments. A fixed anti-impact bumper pad softens the stroke ends. The S code means a magnet is fitted, so CMSG, DMSG or EMSG switches can be mounted for end-of-stroke signalling. The 1/8" port is the same on every MTG bore, and mounting options include LB foot, FA flange, CB clevis and SDB pivot plus I and Y rod knuckles. As a rule of thumb, treat about 0.6 of the pull force - roughly 80 N, or an 8 kg vertical load - as a safe working figure.

Where the Airtac MTG Stainless Steel Mini Cylinder MTG25X100S Is Used
Retract a locking pin
Air pulls the pin out of a fixture or die on demand; if air is lost, the spring pushes the pin back out to its extended rest position for a predictable fail-safe state.
Tension a belt or web
The spring keeps the idler roller pushed out to maintain tension, and air retracts it to release or re-thread - a classic one-way pull duty within the 132.6 N pull at 0.5 MPa.
Close a small shutter or gate
Use the 100 mm stroke to draw a light slide, shutter or gate closed on the air stroke, with the spring reopening it automatically when pressure is removed.
Is the Airtac MTG Stainless Steel Mini Cylinder MTG25X100S the Right Cylinder?
Size the MTG by net pull force, not bore alone. This 25 mm bore gives 132.6 N at 0.5 MPa and 215 N at 0.7 MPa, already net of the spring; halving that gives a realistic continuous load of about 6-7 kg. If you need more pull, step up to MTG32 (224.8 N at 0.5 MPa) or MTG40 (339.1 N at 0.5 MPa); MTG20 (84.8 N) suits lighter duties. Remember the direction of operation: the spring extends the rod and air retracts it, so your work stroke must be a pull. The spring-return design sets a 0.2 MPa (28 psi) minimum working pressure and caps standard strokes at 150 mm for this bore, so 100 mm is within range - but for two-way travel or longer strokes choose the double-acting MG instead. Add LB, FA, CB or SDB mounting and I/Y knuckles as needed; the S code on this model already allows CMSG/DMSG/EMSG switch mounting. Thread is PT; G and NPT are available on request.

- ✓ 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 MTG Stainless Steel Mini Cylinder MTG25X100S FAQ
Net pull (already after the spring) is 132.6 N at 0.5 MPa and 215 N at 0.7 MPa. Operating pressure is 0.2-1.0 MPa (28-145 psi) with a 1.5 MPa (215 psi) proof pressure, fluid is air filtered to 40 um, temperature range -20 to +70 C, and speed 50-800 mm/s. The port is 1/8" and the rod is 10 mm with an M10x1.25 male thread.
The internal spring extends the rod to its rest position; compressed air retracts (pulls) it on the work stroke, and on air loss the spring pushes the rod back out - it does not hold a load, and the fixed bumper pad only softens the stroke end, it is not a brake. The S code means a magnet is fitted, so CMSG, DMSG or EMSG switches can be mounted. Unlike the MSG (single acting push) the MTG pulls; unlike the double-acting MG it moves in one powered direction only.
