Airtac MTF Mini Cylinder MTF25X25SCA
The AirTAC Airtac MTF Mini Cylinder MTF25X25SCA is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø25mm bore and 25mm 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 MTF25X25SCA
Delivering 153.6 N of net pull force at 0.5 MPa, this JIS-standard round-body mini cylinder utilizes a SUS304 stainless barrel and riveted aluminium covers to save mounting length compared to ISO 6432 equivalents. The MTF25X25SCA is a single-acting pull type where an internal spring holds the rod extended at rest, while supplied air retracts it. Because the spring actively pushes the rod out, the assembly fails safely to the extended position if air pressure drops.
Featuring a 25 mm bore, a 10 mm rod, and a 1/8" port, it provides a computed safe working load of roughly 92 N (about 60 percent of its 0.5 MPa rating). This translates to an effective vertical lift capacity of approximately 7.8 kg when applying a 2:1 safety margin. The integrated -S magnet enables position sensing with CMSG, DMSG, or EMSG switches, and the CA back cover supplies a rear pivot point for articulated mounting.

Where the Airtac MTF Mini Cylinder MTF25X25SCA Is Used
Tensioning Systems
Uses the 153.6 N pull force to maintain strap or wire tension, automatically snapping back to the extended position to slacken the line upon air loss.
Fail-Safe Valve Control
Holds a valve open via the internal spring and pulls it closed on air signal, ensuring the mechanism defaults to the extended open state during an outage.
Clamp Retraction
Pulls a packaging clamp out of the way with 236 N at 0.7 MPa, relying on the spring to push the clamp into the blocking position when air is removed.
Is the Airtac MTF Mini Cylinder MTF25X25SCA the Right Cylinder?
When sizing this 25 mm bore unit, evaluate the required tension against its 153.6 N pull at 0.5 MPa. If your application demands less force, step down to the MTF20 which yields 93.4 N; if more is needed, step up to the MTF32 rated at 266.8 N. This single-acting pull configuration is optimal for spring-open, air-close tasks like tensioning or clamping, where losing air pressure safely returns the load to the extended state. Operation requires a minimum of 0.2 MPa to overcome the internal spring, and you can pair the -S magnet option with CMSG, DMSG, or EMSG sensors for end-of-stroke confirmation.
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 MTF25X25SCA FAQ
This 25 mm bore cylinder provides 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 drives the rod to the extended position, meaning the cylinder fails to extended when air pressure is lost. It cannot hold a mid-stroke load; for that, a double-acting MF cylinder with an external rod lock is required. The SUS304 stainless barrel also provides mild washdown resistance.
