About the Airtac MTG Stainless Steel Mini Cylinder MTG32X50
The AirTAC MTG32X50 is a single acting, spring-return JIS mini cylinder with a round riveted body: the internal spring holds the rod extended at rest, and compressed air retracts (pulls) it on the work stroke. With a 32 mm bore and 50 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 what you see is what reaches the load. Because air is only needed on the pull stroke, a single 1/8" supply line is all the valve side requires, which keeps plumbing simple on one-way draw, retract, close or tension motions.
Construction suits damp and washdown-adjacent lines: a SUS304 stainless barrel, a hard-chrome plated (20 um) carbon steel rod with an M10x1.25 male thread, rolled covers and a fixed anti-impact bumper pad that softens the stroke ends. Operating pressure is 0.2-1.0 MPa (28-145 psi) with 1.5 MPa (215 psi) proof, air filtered to 40 um, -20 to +70 C and 50-800 mm/s speed. A practical sizing check: at 0.5 MPa the pull is roughly 23 kgf, so halving it gives a safe working load of about 11 kg. If you need position feedback, order the -S magnet option for CMSG, DMSG or EMSG switches.

Where the Airtac MTG Stainless Steel Mini Cylinder MTG32X50 Is Used
Retracting a locking pin
Air pulls the 12 mm rod in to withdraw a locating or locking pin; on air loss the spring pushes the pin back out to its engaged rest position automatically.
Web and tape tensioning
The constant spring extension keeps a roller loaded while the 224.8 N pull at 0.5 MPa draws the web in for tension control on light packaging or printing lines.
Closing a shutter or gate
One valve signal retracts the rod to slide a small guard shutter or divertor gate closed; the spring reopens it the moment air is removed, a fail-safe motion with no second line.
Is the Airtac MTG Stainless Steel Mini Cylinder MTG32X50 the Right Cylinder?
Choose the MTG32X50 when your motion is a one-way pull and 224.8 N at 0.5 MPa covers the load: that is roughly 23 kgf, or about 11 kg with the usual 50% safety margin. The MTG range steps from bore 20 (84.8 N) through 25 (132.6 N) up to bore 40 (339.1 N), so move up to MTG40 if you need more pull or down to MTG25 to save space. Remember the direction of operation: the spring extends the rod and air retracts it, and the spring sets a 0.2 MPa minimum working pressure. Spring return also caps the standard stroke at 150 mm for this bore; for longer travel or powered two-way motion step up to the double-acting MG series. Mounting options are LB foot, FA flange, CB clevis and SDB pivot, plus I and Y rod knuckles, and PT threading is standard (G or NPT on request). This SKU has no magnet, so add the S code if you plan 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 MTG32X50 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, air filtered to 40 um, working temperature -20 to +70 C and speed 50-800 mm/s. The spring return sets the 0.2 MPa floor, and the maximum standard stroke for this 32 mm bore is 150 mm.
On the MTG the spring extends the rod and air retracts (pulls) it, so on air loss the rod fails to its extended position; the fixed bumper pad only softens the stroke ends 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 on both sides for powered two-way travel and longer strokes. This SKU has no magnet; order the -S option to mount CMSG, DMSG or EMSG switches.
