About the Airtac MTG Stainless Steel Mini Cylinder MTG32X100S
The MTG32X100S is a JIS-standard round-body mini cylinder built for single acting PULL duty: an internal spring holds the rod out at rest, and compressed air retracts (pulls) it through the 100 mm stroke. With a 32 mm bore it delivers about 224.8 N of pull at 0.5 MPa and 363 N at 0.7 MPa, figures already net of the spring, so what you see is what reaches the load. Only one air line is needed, which simplifies plumbing and keeps valve and fitting costs down on one-way draw, retract, close or tension motions.
Construction suits damp and washdown-adjacent environments: a SUS304 stainless barrel, a hard-chrome plated carbon-steel rod (20 um chrome), riveted covers and a fixed anti-impact bumper pad that softens the stroke ends. The fitted magnet (the S in the code) accepts CMSG, DMSG or EMSG switches for end-of-stroke signalling. Air supply is filtered to 40 um at 0.2-1.0 MPa (28-145 psi), with 1.5 MPa (215 psi) proof pressure, -20 to +70 C operation and a 50-800 mm/s speed range. As a practical sizing check, plan on roughly 13 kg of safe working pull at 0.5 MPa (about 0.6 of the rated force).

Where the Airtac MTG Stainless Steel Mini Cylinder MTG32X100S Is Used
Retracting a locking pin
The spring pushes the pin out to its engaged position, and a burst of air pulls it back to release a fixture or die. With about 224.8 N of pull at 0.5 MPa, the MTG32X100S withdraws spring-loaded pins reliably from a single 1/8" air line.
Tensioning a belt or web
Mounted on a sliding idler, the rod is held out by the spring to keep steady tension on a belt, film or tape, and air pulls the idler in for threading or release. The 100 mm stroke covers take-up travel on short conveyor and packaging heads.
Closing a shutter or guard door
The spring holds a sliding shutter, chute flap or guard open, and the cylinder pulls it closed when the machine cycles. Fail-safe behaviour is built in: on air loss the spring returns the rod to its extended rest position.
Is the Airtac MTG Stainless Steel Mini Cylinder MTG32X100S the Right Cylinder?
Size the MTG32X100S when your one-way pull needs roughly 130-220 N of realistic working force: at 0.5 MPa it pulls 224.8 N net of the spring, and a 0.6 safety factor leaves about 13 kg of dependable pull for clamps, pins or web tensioners. If that is marginal, step up to the MTG40 (339.1 N at 0.5 MPa); if it is generous, the MTG25 (132.6 N) saves air and money. Remember the direction of travel: the spring extends the rod and air retracts it, and the minimum working pressure is 0.2 MPa because the spring must be overcome. The spring return also caps standard strokes at 150 mm for this bore, so 100 mm is comfortably within range; for two-way travel or longer strokes choose the double-acting MG instead. Mounting options are LB foot, FA flange, CB clevis and SDB pivot, plus I and Y rod knuckles, and the fitted magnet works with CMSG/DMSG/EMSG switches. Ports are 1/8" on every MTG bore; 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 MTG32X100S FAQ
At 0.5 MPa it pulls 224.8 N, rising to 363 N at 0.7 MPa; both figures are net of 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, working temperature -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.
The internal spring extends the rod to its rest position; compressed air on the single port retracts (pulls) it. On air loss the rod springs back out, so the cylinder does not hold a load, and the fixed bumper pad only softens the stroke ends. This S-coded model carries a magnet, so CMSG, DMSG or EMSG switches can be clipped on for end-of-stroke signals. It is the mirror image of the MSG (spring push, air pull... actually air push) and, unlike the double-acting MG, it moves powerfully in one direction only.
