Airtac MTF Mini Cylinder MTF25X10SCA
The AirTAC Airtac MTF Mini Cylinder MTF25X10SCA 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 MTF25X10SCA
Generating 153.6 N of pull at 0.5 MPa, this single-acting pull cylinder uses an internal spring to keep the rod extended, while compressed air retracts it. The MTF25X10SCA features a 25 mm bore, a 10 mm stroke, and a 1/8 inch port. Because the spring constantly pushes outward, the assembly fails to the extended position upon air loss, making it highly reliable for spring-open and air-close operations.
Built as a JIS-standard round-body mini cylinder, the riveted construction pairs a SUS304 stainless steel barrel with aluminium covers, offering shorter overall dimensions than an equivalent ISO 6432 unit. The integrated -S magnet supports CMSG, DMSG, and EMSG switches for position sensing. For practical sizing, the net pull yields a safe working load of roughly 92 N, which translates to lifting or holding about 7.8 kg vertically with a 2:1 safety margin. End-of-stroke deceleration is handled by fixed TPU bumper pads, and the CA back cover provides a rear pivot mount.

Where the Airtac MTF Mini Cylinder MTF25X10SCA Is Used
Tension Mechanisms
Pulls with 153.6 N at 0.5 MPa to maintain tension on belts or films, automatically relaxing to the extended position if the air supply drops.
Lid Closing
Uses compressed air via the 1/8 inch port to pull shut a 7.8 kg vertical lid, relying on the spring to push it back open safely.
Fail-Safe Gates
Holds a guard open under spring pressure; venting the air causes the cylinder to extend instantly, securing the area during an outage.
Is the Airtac MTF Mini Cylinder MTF25X10SCA the Right Cylinder?
When sizing this 25 mm bore model, compare it directly with adjacent bores using 0.5 MPa figures: the MTF20 provides 93.4 N of pull, while the larger MTF32 delivers 266.8 N. Choose this MTF25X10SCA when your mechanism requires tensioning, lid closing, or a fail-safe-extended state where air actively pulls the load. A minimum operating pressure of 0.2 MPa is required to overcome the internal spring. Alongside the CA pivot back cover, you can utilize LB foot, FA flange, SDB pivot-block, or TC trunnion mounting styles to fit your frame.
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 MTF25X10SCA FAQ
This single-acting pull cylinder generates a net pull force of 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 return spring, with a maximum pressure of 1.0 MPa and a proof pressure of 1.5 MPa.
The internal spring constantly extends the rod, meaning air is only used to retract it. If air pressure is lost, the spring drives the rod to the fully extended position; it will not hold a mid-stroke load. The SUS304 stainless barrel resists mild corrosion, and the -S magnet allows CMSG or DMSG sensors to track its extended and retracted states.
