Airtac MTF Mini Cylinder MTF25X15CM
The AirTAC Airtac MTF Mini Cylinder MTF25X15CM is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø25mm bore and 15mm 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 MTF25X15CM
Delivering 153.6 N of pull at 0.5 MPa (236 N at 0.7 MPa), this JIS-standard round-body mini cylinder uses a SUS304 stainless barrel and riveted aluminium covers to save mounting length compared to an ISO 6432 unit. The MTF25X15CM is a single-acting pull type: an internal spring pushes the 10 mm rod out to its extended rest, while supplying air to the 1/8" port retracts it. This fail-safe-to-extended behavior suits spring-open and air-close tasks.
The quoted forces are already net of the spring, requiring a minimum 0.2 MPa operating pressure to overcome it. With a 15 mm stroke, fixed TPU bumper pads absorb end-of-stroke impacts. For buyers, the effective pull translates to roughly 7.8 kg of vertical lift with a 2:1 safety margin. This non-magnet SKU cannot host CMSG/DMSG/EMSG sensors; adding the -S option enables that capability.

Where the Airtac MTF Mini Cylinder MTF25X15CM Is Used
Tensioning Systems
Pulls with 153.6 N at 0.5 MPa to maintain strap or web tension, releasing the load safely to the extended position if air pressure drops.
Lid Lifting
Uses air to pull a 15 mm stroke and close lids, relying on the internal spring to push the 10 mm rod back out and hold the cover open securely.
Fail-Safe Open Valves
Vents or opens process lines automatically on air loss, as the spring drives the rod to the fully extended rest state without needing power.
Is the Airtac MTF Mini Cylinder MTF25X15CM the Right Cylinder?
When sizing this 25 mm bore, compare its 153.6 N @0.5 MPa pull both ways: step down to the MTF20 for 93.4 N, or up to the MTF32 for 266.8 N. Choose this single-acting pull configuration when you need tensioning, closing, or a fail-safe extended position upon air loss. It operates between 0.2 and 1.0 MPa. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion, and the CM round-end back cover fits compact spaces. Because this specific SKU lacks the -S magnet, it cannot accept position sensors.
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 MTF25X15CM FAQ
It provides a net pull force of 153.6 N at 0.5 MPa and 236 N at 0.7 MPa. Operating pressure ranges from 0.2 MPa (the minimum needed to overcome the spring) to 1.0 MPa, with a 1.5 MPa proof pressure.
The spring constantly extends the 10 mm rod, and air retracts it. On air loss, the rod fails to the fully extended position; it cannot hold an arbitrary mid-stroke load. The SUS304 stainless build resists mild washdown.
