Airtac MTF Mini Cylinder MTF25X80SU
The AirTAC Airtac MTF Mini Cylinder MTF25X80SU is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø25mm bore and 80mm stroke, 1/8" air ports and a SUS304 stainless-steel barrel for mildly corrosive environments. For the same bore and stroke it is shorter than an ISO 6432 cylinder, saving mounting space.

About the Airtac MTF Mini Cylinder MTF25X80SU
Generating 153.6 N of net pull at 0.5 MPa, this JIS-standard round-body mini cylinder is built for spring-open, air-close jobs. The internal spring constantly pushes the 10 mm rod out to its extended rest, while supplying air to the 1/8" port retracts it. Because the spring drives the rod out, the cylinder fails safely to the extended position on any air loss. The SUS304 stainless barrel and riveted aluminium covers resist mild washdown, and the body is purposefully shorter than an ISO 6432 unit of the same 25 mm bore and 80 mm stroke.
This single-acting pull configuration means air only ever retracts the rod; it cannot push loads outward. The quoted 236 N pull at 0.7 MPa is already net of the internal spring. For sizing, this yields a safe working load of about 92 N (roughly 60% of the 0.5 MPa figure), or a vertical lift capacity near 7.8 kg with a 2:1 margin. The stroke terminates on fixed TPU bumper pads, and the included -S magnet enables CMSG, DMSG, or EMSG position sensing.

Where the Airtac MTF Mini Cylinder MTF25X80SU Is Used
Tensioning Web Material
Uses the 153.6 N pull at 0.5 MPa to maintain constant tension on packaging film, retracting the rod against the spring to absorb slack.
Fail-Safe Gate Opening
Holds an access door open via air retraction; upon air loss, the internal spring snaps the 10 mm rod back out to push the gate open.
Clamp Retraction
Pulls a 7.8 kg vertical clamp back safely with a 2:1 margin, keeping the work area clear when the 1/8" port is pressurized.
Is the Airtac MTF Mini Cylinder MTF25X80SU the Right Cylinder?
If 153.6 N of net pull at 0.5 MPa is too much, step down to the MTF20 bore which provides 93.4 N; if you need more retraction force, the MTF32 offers 266.8 N. This single-acting pull design fits applications requiring a fail-safe extended state, like tensioning or holding gates closed via air pressure. You must supply at least 0.2 MPa to overcome the internal spring. This U flat-end rear cover model includes the -S magnet for electronic or reed switches, and accepts LB foot, FA flange, SDB pivot, or TC trunnion mounts.
Quick checklist

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 Use correct back cover (CA/U/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MTF Mini Cylinder MTF25X80SU FAQ
The net pull force is 153.6 N at 0.5 MPa and 236 N at 0.7 MPa. It requires a minimum operating pressure of 0.2 MPa to overcome the internal return spring and retract the rod.
The spring constantly extends the rod, meaning the cylinder fails to the extended position on air loss and cannot hold mid-stroke loads. The -S option adds a piston magnet for CMSG, DMSG, or EMSG sensors, while the SUS304 stainless barrel handles mild corrosion.
