Airtac MTF Mini Cylinder MTF25X10SU
The AirTAC Airtac MTF Mini Cylinder MTF25X10SU is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø25mm bore and 10mm 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 MTF25X10SU
Delivering 153.6 N of pull force at 0.5 MPa, this JIS-standard round-body mini cylinder uses a SUS304 stainless barrel and riveted aluminium covers. The MTF25X10SU is a single-acting pull type: an internal spring holds the rod extended at rest, while supplying air to the 1/8 inch port retracts it. This fail-safe design naturally drives the rod back out upon air loss, making it ideal for spring-open tasks. It also provides a shorter mounting envelope than an ISO 6432 unit of the same bore and stroke.
The Ø10 mm rod features an M10x1.25 male thread, and the U flat-end rear cover simplifies direct mounting. With a 10 mm stroke, fixed TPU bumper pads absorb end-of-stroke impacts across the 50-800 mm/s speed range. The built-in magnet (-S) supports CMSG, DMSG, and EMSG position switches. For sizing, its effective vertical lift is about 7.8 kg using a 2:1 safety margin, equating to a roughly 92 N safe working load.

Where the Airtac MTF Mini Cylinder MTF25X10SU Is Used
Tension Control
Maintains steady pulling tension on belts or filaments with its 153.6 N force, releasing the load only when compressed air retracts the rod.
Fail-Safe Open Gate
Holds a guard gate open via spring force; air retraction pulls it closed. Loss of air pressure automatically extends the rod back to the open state.
Clamp Release
Pulls back a lightweight packaging clamp using the 1/8 inch air port, allowing the internal spring to re-extend the 10 mm stroke for part clearance.
Is the Airtac MTF Mini Cylinder MTF25X10SU the Right Cylinder?
When sizing this 25 mm bore, compare its 153.6 N pull at 0.5 MPa against the smaller MTF20 (93.4 N) or the larger MTF32 (266.8 N). This single-acting pull format fits applications needing a fail-safe extended state, such as tensioning or air-close mechanisms. A minimum operating pressure of 0.2 MPa is required to overcome the internal spring. You can pair the -S magnet option with CMSG, DMSG, or EMSG sensors, and mount the unit using LB foot, FA flange, SDB pivot, or TC trunnion brackets.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/CM) & mount (LB/FA/SDB/TC)
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 MTF25X10SU FAQ
It provides a net pull force of 153.6 N at 0.5 MPa and 236 N at 0.7 MPa. A minimum operating pressure of 0.2 MPa is required to overcome the return spring, with a maximum limit of 1.0 MPa.
The spring constantly extends the rod, meaning air only retracts it and the cylinder fails to the extended position on air loss. The -S option includes a piston magnet for CMSG, DMSG, or EMSG sensors, and the SUS304 stainless build resists mild washdown environments.
