About the Airtac MTG Stainless Steel Mini Cylinder MTG25X150
The AirTAC MTG25X150 is a single acting, pull-type JIS mini cylinder with a round SUS304 stainless barrel and a hard-chrome plated 10 mm rod. The internal spring holds the rod extended at rest, and compressed air retracts (pulls) it on the work stroke, so one air line is all the valve circuit needs. At the full 150 mm stroke this bore delivers about 132.6 N of net pull at 0.5 MPa and 215 N at 0.7 MPa, already after the spring, with a minimum working pressure of 0.2 MPa (28 psi) and a speed range of 50 to 800 mm/s.
In practice, budget roughly 80 N (about 8 kg) as a safe continuous working pull at 0.5 MPa, which keeps the spring penalty and line losses in hand. The riveted covers carry a fixed anti-impact bumper pad that softens the stroke ends, and the two-way lubricant-storing piston seal extends service intervals in damp or washdown-prone areas. The 150 mm stroke is the maximum standard length for this 25 mm bore, and the JIS footprint keeps replacement simple. If you need two-way powered travel or a longer stroke, step up to the double-acting MG series; add the S code if you want CMSG, DMSG or EMSG switch sensing.

Where the Airtac MTG Stainless Steel Mini Cylinder MTG25X150 Is Used
Retract a locating pin
Air pulls the pin out of a fixture nest at up to 132.6 N at 0.5 MPa; when the valve vents, the spring pushes the pin back to its extended rest position automatically.
Draw a tape or web tensioner
The 150 mm stroke takes up slack on a light web or tape line, with roughly 80 N of safe continuous pull at 0.5 MPa and a single 1/8" air line doing the work.
Close a slide shutter or gate
Air retracts the shutter closed on demand; on power loss the spring returns it open, a fail-safe behaviour suited to small chutes and access covers.
Is the Airtac MTG Stainless Steel Mini Cylinder MTG25X150 the Right Cylinder?
Choose the MTG25X150 when your motion is a one-way pull of up to 150 mm and the spring can push the rod back out on air loss: it gives about 132.6 N net pull at 0.5 MPa and 215 N at 0.7 MPa. If that is marginal, the MTG32 (224.8 N at 0.5 MPa) is the next size up; the MTG20 (84.8 N) suits lighter draws. Remember the spring extends the rod and air retracts it, working pressure starts at 0.2 MPa (28 psi), and spring return caps standard strokes at 150 mm, so for longer or two-way travel use the double-acting MG. Mounting: LB foot, FA flange, CB clevis or SDB pivot, plus I and Y rod knuckles. Every bore uses a 1/8" port and PT thread as standard (G and NPT optional). The base unit has no magnet; order the S code to fit CMSG, DMSG or EMSG switches.

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 MTG25X150 FAQ
The net pull, already after the return spring, is 132.6 N at 0.5 MPa and 215 N at 0.7 MPa. Operating pressure is 0.2 to 1.0 MPa (28 to 145 psi) with a proof pressure of 1.5 MPa (215 psi), fluid is air filtered to 40 um, speed range is 50 to 800 mm/s, and the temperature range is -20 to +70 C. The port is 1/8" on this bore.
In the MTG the spring extends the rod and compressed air retracts (pulls) it, so on air loss the rod fails to its extended position. The MSG is the mirror image: air pushes and the spring retracts. The MG is double acting, powered in both directions with no spring, and suits longer strokes or two-way travel. This base model has no magnet, so no CMSG, DMSG or EMSG sensor can be mounted unless you order the S code.
