About the Airtac MTG Stainless Steel Mini Cylinder MTG20X100
The AirTAC MTG20X100 is a JIS-standard round-body mini cylinder built as a single acting PULL unit: an internal spring holds the rod extended at rest, and compressed air retracts (pulls) it on the work stroke. With a 20 mm bore and 100 mm stroke it delivers a net pull of 84.8 N at 0.5 MPa and 137.5 N at 0.7 MPa, already after the spring, so the figures you see are the forces available at the rod. Only one air line is needed, which keeps plumbing simple on machines where the motion is a one-way draw, retract, close or tension action.
Construction suits damp and washdown-adjacent lines: a SUS304 stainless barrel with a hard-chrome (20 um) carbon-steel rod, riveted rolled covers, a two-way lubricant-storing piston seal and a fixed anti-impact bumper pad at the stroke end. The 8 mm rod carries a male M8x1.25 thread and air connects through a 1/8" port. Operating pressure is 0.2-1.0 MPa (28-145 psi) with proof at 1.5 MPa (215 psi), temperature -20 to +70 C and speed 50-800 mm/s. As a practical sizing insight, take about 60 percent of the 84.8 N pull as a safe working figure, roughly 5 kg of continuous load. If you need rod position feedback, order the -S magnet version for CMSG, DMSG or EMSG switches.

Where the Airtac MTG Stainless Steel Mini Cylinder MTG20X100 Is Used
Retracting a locating pin
The spring pushes the pin out to its rest position and the MTG20X100 pulls it back clear of the fixture when air is applied, using a single 1/8" line and 84.8 N of pull at 0.5 MPa.
Drawing a light web or tape
Mount the cylinder to draw a thin web, tape or film taut across a guide: the spring keeps tension out at rest and the 20 mm bore pulls the take-up in at 50-800 mm/s.
Closing a small shutter or gate
Use the pull stroke to slide a light shutter, gate or diverter closed on a packaging or inspection station, with the spring reopening it automatically on air loss.
Is the Airtac MTG Stainless Steel Mini Cylinder MTG20X100 the Right Cylinder?
Size the MTG20X100 by pull force, not bore alone: 84.8 N at 0.5 MPa (about 8.6 kgf, so plan on roughly 5 kg of realistic working load) and 137.5 N at 0.7 MPa. It is the smallest MTG bore; if your pull demand exceeds this, step up to MTG25 (132.6 N), MTG32 (224.8 N) or MTG40 (339.1 N) at 0.5 MPa. Remember the direction of travel: the spring extends the rod and air retracts it, with a 0.2 MPa (28 psi) minimum working pressure to overcome the spring. The spring-return design caps standard strokes at 150 mm for this bore, so 100 mm is within range; for longer travel or two-way powered motion choose the double-acting MG series instead. Mounting options are LB foot, FA flange, CB clevis and SDB pivot, plus I and Y rod knuckles. This unit has no magnet, so no position sensor can be fitted; specify the -S code if you need CMSG, DMSG or EMSG switches. Threads are PT as standard, with G and NPT available.

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 MTG20X100 FAQ
Net pull (already after the spring) is 84.8 N at 0.5 MPa and 137.5 N at 0.7 MPa. Operating pressure is 0.2-1.0 MPa (28-145 psi), with 0.2 MPa as the minimum to overcome the spring; proof pressure is 1.5 MPa (215 psi). Speed range is 50-800 mm/s, temperature -20 to +70 C, and the fluid must be air filtered to 40 um.
The internal spring extends the rod to its rest position; applying air retracts (pulls) it. On air loss the rod returns to extended, so the cylinder does not hold a load, and the fixed bumper pad only softens the stroke end. This is the opposite of the MSG push type and simpler than the double-acting MG. This model has no magnet, so no sensor can be mounted; order the -S version to fit CMSG, DMSG or EMSG switches.
