Airtac MTF Mini Cylinder MTF25X15U
The AirTAC Airtac MTF Mini Cylinder MTF25X15U 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 MTF25X15U
Generating 153.6 N of pull at 0.5 MPa, this AirTAC MTF25X15U is a JIS-standard round-body mini cylinder built for single-acting tension and return-to-extended tasks. An internal spring pushes the 10 mm rod out, while air through the 1/8" port retracts it. Because the spring holds the rod out, the cylinder fails safely to the extended position if air pressure drops. The riveted SUS304 stainless barrel and aluminium covers resist mild washdown, and the U flat-end back cover suits tight footprints.
This 15 mm stroke variant delivers a computed safe working load of roughly 92 N (about 60% of its 0.5 MPa rating). With a 2:1 margin, it vertically lifts or holds around 7.8 kg. It uses fixed TPU bumper pads for end-of-stroke damping rather than an adjustable air cushion. Note this specific SKU lacks the -S magnet, so it cannot host CMSG, DMSG, or EMSG sensors.

| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 153.6 N |

Where the Airtac MTF Mini Cylinder MTF25X15U Is Used
Tensioning Web Material
Uses the 153.6 N pull to maintain consistent tension on filaments or webs, releasing the load when air is removed.
Fail-Safe Gate Opening
Holds an access gate open via spring force; applying air retracts the rod to pull the gate closed safely.
Short-Stroke Retraction
Pulls a small 15 mm latch or pin out of the way in automated tooling, relying on the spring to reset it.
Is the Airtac MTF Mini Cylinder MTF25X15U the Right Cylinder?
Choose this 25 mm bore if the 93.4 N pull of the MTF20 is insufficient, but the 266.8 N of the MTF32 is overkill. It fits spring-open, air-close mechanisms, and tensioning duties needing at least 0.2 MPa to overcome the return spring. For position feedback, select the -S magnet version instead, as this base unit cannot accept switches. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion.
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 MTF25X15U FAQ
It provides a single-acting pull force of 153.6 N at 0.5 MPa and 236 N at 0.7 MPa, measured net of the spring. You must supply at least 0.2 MPa of air to overcome the spring and retract the rod.
No, this specific SKU does not include a magnet. You must order the -S variant to use CMSG, DMSG, or EMSG magnetic switches. Additionally, it uses fixed TPU bumpers instead of an adjustable cushion.
