About the Airtac MTG Stainless Steel Mini Cylinder MTG20X150
The MTG20X150 is a single acting, spring-return PULL cylinder in AirTAC's JIS round-body mini series. At rest the internal spring holds the rod extended; applying air retracts (pulls) the rod, so one air line covers the whole work stroke. With a 20 mm bore and 150 mm stroke it delivers about 84.8 N of net pull at 0.5 MPa and 137.5 N at 0.7 MPa, already after the spring, and it runs from a 0.2 MPa (28 psi) minimum up to 1.0 MPa (145 psi). That net force translates to roughly 5 kg of safe vertical load using the common 0.6 safety factor, so size the task accordingly.
Construction suits damp and washdown corners of a plant: a SUS304 stainless barrel, a hard-chrome plated rod (20 um chrome), riveted rolled covers, a two-way lubricant-storing piston seal and a fixed anti-impact bumper pad at each stroke end. The 150 mm stroke is the maximum standard for this bore, since the return spring caps travel; ports are 1/8" on every MTG bore, the male rod thread is M8x1.25, and speed is 50-800 mm/s. Add the S code if you later want CMSG, DMSG or EMSG magnetic sensing.

Where the Airtac MTG Stainless Steel Mini Cylinder MTG20X150 Is Used
Retract a locking pin
Air pulls the pin out of a fixture or die on command, and the spring pushes it back into the locked position the moment air is lost, giving a fail-safe extended rest state.
Tension a light belt or web
The spring-biased extended rod keeps an idler roller loaded; venting the air lets the spring restore tension on thin belts, films or tapes at up to 150 mm of take-up travel.
Close a slide or shutter
Draw a small gate, chute flap or shutter closed with 84.8 N of pull at 0.5 MPa; the spring reopens it automatically on air loss without any second valve or line.
Is the Airtac MTG Stainless Steel Mini Cylinder MTG20X150 the Right Cylinder?
Choose the MTG20X150 when your motion is a one-way pull of up to 150 mm and the load needs no more than about 84.8 N of net pull at 0.5 MPa (137.5 N at 0.7 MPa); this is the smallest bore in the MTG range, so step up to MTG25, MTG32 or MTG40 if the draw force is higher. Remember the direction of action: 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. If you need two-way powered travel or a stroke beyond 150 mm, 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; specify the S code to enable CMSG/DMSG/EMSG position sensing, and pick PT (blank), G or NPT ports.

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 MTG20X150 FAQ
The net pull, already after the return spring, is 84.8 N at 0.5 MPa and 137.5 N at 0.7 MPa. Because the spring must be overcome, the minimum working pressure is 0.2 MPa (28 psi), with a normal range of 0.2-1.0 MPa (28-145 psi), proof pressure of 1.5 MPa (215 psi), operating temperature of -20 to +70 C and speed of 50-800 mm/s on air filtered to 40 um.
This is the opposite of the MSG push type: the internal spring holds the rod OUT at rest, and compressed air retracts (pulls) it for the work stroke; on air loss the spring returns the rod to extended, so it does not hold a load and the bumper pad is not a brake. A position switch (CMSG, DMSG or EMSG) needs the optional S magnet code, which this no-S SKU does not carry.
