About the Airtac MTG Stainless Steel Mini Cylinder MTG32X50S
The AirTAC MTG32X50S 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 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 the 0.2 MPa (28 psi) minimum working pressure is what matters on the bench. One air line is all it needs, which keeps plumbing and valve cost down on one-way draw, retract, close, or tension motions. The fitted magnet (the S code) lets you add CMSG, DMSG, or EMSG switches for end-of-stroke signalling.
Construction suits damp and washdown-adjacent lines: a SUS304 stainless barrel, a hard-chrome (20 um) carbon-steel rod, riveted rolled covers, and a fixed anti-impact bumper pad that softens the stroke ends without locking or braking anything. If the air drops, the spring simply pushes the rod back to its extended rest position. For practical sizing, treat about 135 N as a realistic working pull at 0.5 MPa, which supports a safe vertical load of roughly 13 kg. Need two-way travel or more than the 150 mm standard stroke limit? Step up to the double-acting MG series instead.

Where the Airtac MTG Stainless Steel Mini Cylinder MTG32X50S Is Used
Retracting a locating pin
Air pulls the 12 mm rod in to withdraw a pin from a fixture, and the spring pushes it back out to the engaged position the moment pressure drops, with the magnet signalling the retracted end.
Drawing a web or tape into tension
About 224.8 N of net pull at 0.5 MPa gives a controlled one-way draw on light web, tape, or film take-up arms, with the spring taking up slack on release.
Closing a slide or shutter
One solenoid valve closes a guard shutter or slide gate on the work stroke; on air loss the spring reopens it to the extended rest position, a fail-safe default.
Is the Airtac MTG Stainless Steel Mini Cylinder MTG32X50S the Right Cylinder?
Choose the MTG32X50S when your motion is a one-way pull of about 224.8 N at 0.5 MPa (363 N at 0.7 MPa) over a 50 mm stroke. Within the MTG range, bore 32 sits above the 20 and 25 sizes (84.8 N and 132.6 N at 0.5 MPa) and below the 40 (339.1 N), so size up if your load plus friction approaches the net pull. Remember the behaviour: the spring extends the rod and air retracts it, and the spring-return design caps standard strokes at 150 mm for this bore; for two-way travel or longer strokes, use the double-acting MG. The minimum working pressure is 0.2 MPa (28 psi), well below the 1.0 MPa (145 psi) maximum. Ports are 1/8" on every MTG bore, with PT thread standard and G or NPT options. Mount with LB foot, FA flange, CB clevis, or SDB pivot brackets, plus I or Y rod knuckles; the fitted magnet accepts 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 MTG32X50S FAQ
The 32 mm bore gives a net pull of 224.8 N at 0.5 MPa and 363 N at 0.7 MPa, already after the return spring. 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, a speed range of 50-800 mm/s, and a temperature range of -20 to +70 C. The port is 1/8" and the rod is 12 mm with an M10x1.25 male thread.
In the MTG the spring extends the rod and air retracts (pulls) it, so one air line drives the work stroke and the spring returns the rod out on air loss. The MSG is the mirror image: air pushes and the spring retracts. The MG is double acting, with air on both strokes for two-way travel and strokes beyond the 150 mm spring-return limit. This S-coded model carries a magnet for CMSG, DMSG, or EMSG switches; the fixed bumper pad softens the stroke ends but is not a lock or brake.
