About the Airtac MTG Stainless Steel Mini Cylinder MTG32X25
The AirTAC MTG32X25 is a JIS-standard round-body mini cylinder built as a single acting PULL unit: an internal spring holds the rod out at rest, and compressed air retracts (pulls) it on the work stroke. With a 32 mm bore and 25 mm stroke it delivers about 224.8 N of net pull at 0.5 MPa and 363 N at 0.7 MPa, figures already measured after the spring, so the force you see at the rod thread is what moves your load. The 0.2 MPa (28 psi) minimum working pressure reflects the spring preload, and the full operating band is 0.2-1.0 MPa (28-145 psi) with a 1.5 MPa (215 psi) proof rating. Because only one air line is needed, plumbing stays simple and valve cost drops, which makes this a natural fit for one-way draw, retract, close or tension motions.
Construction suits damp and washdown-adjacent environments: 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 that softens the stroke ends without acting as a lock or brake. The rod is 12 mm with an M10x1.25 male thread and the air port is 1/8" on every MTG bore. At a realistic 0.6 duty factor the 224.8 N pull supports a safe working load of roughly 13 kg (about 135 N), so size the task accordingly. Speed range is 50-800 mm/s and temperature spans -20 to +70 C. For position feedback, order the -S magnet option to enable CMSG, DMSG or EMSG switches.

Where the Airtac MTG Stainless Steel Mini Cylinder MTG32X25 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 released - a fail-safe retract for a 25 mm pin stroke.
Draw a tape or web
The 224.8 N pull at 0.5 MPa gives enough net force to draw a light tape, film or web through a guide on a packaging or converting line, with the spring returning the carriage.
Close a slide or shutter
Use the air stroke to slide a guard, chute gate or shutter closed; the spring reopens it automatically on air loss, and the fixed bumper pad softens both stroke ends.
Is the Airtac MTG Stainless Steel Mini Cylinder MTG32X25 the Right Cylinder?
Choose the MTG32X25 when your motion is a one-directional pull of about 135 N or less at a realistic working pressure (224.8 N net pull at 0.5 MPa, 363 N at 0.7 MPa) and a 25 mm stroke is enough. The spring extends the rod and air retracts it, so on air loss the rod returns to its extended rest position rather than holding a load. The spring-return design caps standard MTG strokes at 150 mm; if you need longer travel or powered movement in both directions, step up to the double-acting MG series instead. Within the MTG range, bore 20 is the smallest pull (84.8 N at 0.5 MPa) and bore 40 the largest (339.1 N), so bore 32 sits in the middle. Remember the 0.2 MPa (28 psi) minimum working pressure imposed by the spring. Mounting options are LB foot, FA flange, CB clevis and SDB pivot, plus I and Y rod knuckles; add the S code for a magnet that enables CMSG, DMSG or EMSG switches. Thread is 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 MTG32X25 FAQ
Net pull (already after the spring) is 224.8 N at 0.5 MPa and 363 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, temperature range -20 to +70 C, and speed 50-800 mm/s. The 0.2 MPa floor exists because the spring must be overcome before the rod moves. Fluid is air filtered to 40 um, and the port is 1/8" on all MTG bores.
In the MTG the spring extends the rod and compressed air retracts (pulls) it - the opposite of the MSG, where air pushes and the spring retracts. The double-acting MG uses air in both directions with no spring, allowing longer strokes and higher force. On air loss the MTG32X25 rod springs back to its extended rest position; it does not hold a load. Add the S magnet option to fit CMSG, DMSG or EMSG position switches.
