About the Airtac MTG Stainless Steel Mini Cylinder MTG20X75
The AirTAC MTG20X75 is a single acting, pull-type JIS round-body mini cylinder: 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 75 mm stroke it delivers about 84.8 N of net pull at 0.5 MPa and 137.5 N at 0.7 MPa, figures already measured against the spring. Because only one air line is needed, plumbing stays simple, and on loss of pressure the spring pushes the rod back out to its extended rest position. The minimum working pressure is 0.2 MPa, with a speed range of 50 to 800 mm/s.
Construction suits damp and washdown-adjacent environments: a SUS304 stainless barrel, a hard-chrome plated rod (20 um chrome), riveted 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 the air port is 1/8". For a realistic working pull, budget roughly 51 N (about 60 percent of rated pull), which supports a safe vertical load near 4 kg on this bore. If you need two-way powered travel or strokes beyond the 150 mm spring-return limit, step up to the double-acting MG series.

Where the Airtac MTG Stainless Steel Mini Cylinder MTG20X75 Is Used
Retract a locating pin
Air pulls the pin out of a fixture on each cycle while the spring pushes it back to its extended, ready position when pressure drops.
Draw a tape or web
The 84.8 N pull at 0.5 MPa gives a light, consistent draw on thin tape or film, with the spring resetting the carriage each stroke.
Close a small shutter
One air line closes a guide or shutter gate; the spring reopens it automatically on air loss, a fail-safe default position.
Is the Airtac MTG Stainless Steel Mini Cylinder MTG20X75 the Right Cylinder?
Choose the MTG20X75 when your motion is a one-way pull of 75 mm and the spring can do the return-out work. At 20 mm bore it is the smallest MTG, giving 84.8 N pull at 0.5 MPa and 137.5 N at 0.7 MPa; for heavier draws pick the MTG25, MTG32 or MTG40. Remember the spring-extends / air-retracts behaviour and the 0.2 MPa minimum pressure, and note the spring-return design caps standard strokes at 150 mm. Mounting options are LB foot, FA flange, CB clevis and SDB pivot, plus I and Y rod knuckles. Add the S code to the model number if you want a magnet for CMSG, DMSG or EMSG switches; this SKU has no magnet, so no sensor can be fitted.

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 MTG20X75 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 to 1.0 MPa (28 to 145 psi) with a 1.5 MPa (215 psi) proof pressure, fluid is air filtered to 40 um, temperature range is -20 to +70 C, and speed is 50 to 800 mm/s. The air port is 1/8" on every MTG bore.
In the MTG the spring extends the rod and air retracts it, so the cylinder fails to its extended position on air loss; the fixed bumper pad only softens the stroke end and does not lock or hold a load. The MSG is the opposite single acting type (air pushes, spring retracts), and the MG is double acting with air in both directions, which also allows strokes beyond the 150 mm spring-return limit. This SKU has no magnet, so position sensing with CMSG, DMSG or EMSG switches requires the S code.
