Airtac MTF Mini Cylinder MTF25X10U
The AirTAC Airtac MTF Mini Cylinder MTF25X10U 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 MTF25X10U
Delivering 153.6 N of net pull force at 0.5 MPa, the AirTAC MTF25X10U is a single-acting, spring-return mini cylinder designed for tensioning and air-close applications. An internal spring normally holds the rod extended, while supplied air retracts it. This JIS-standard round-body unit uses a SUS304 stainless barrel with riveted aluminium covers, offering a shorter mounting envelope than an ISO 6432 cylinder of identical bore and stroke.
This specific SKU features a 10 mm stroke, a Ø10 mm rod with an M10x1.25 male thread, and a 1/8" port. It lacks the -S magnet option, meaning it cannot host CMSG, DMSG, or EMSG sensors. The quoted pull force is already net of the spring resistance, yielding a safe working load of roughly 92 N or a 7.8 kg vertical lift capacity with a 2:1 margin. It relies on fixed TPU bumper pads for end-of-stroke deceleration.

Where the Airtac MTF Mini Cylinder MTF25X10U Is Used
Tensioning Systems
Pulls with 153.6 N at 0.5 MPa to maintain tension on belts or filaments, automatically relaxing to the extended position if air pressure drops.
Lid Lifting
Uses air to pull a 10 mm stroke and close lids, relying on the internal spring to push the cover back open safely during a pneumatic failure.
Clamp Retraction
Draws back holding fixtures with a safe working load of about 92 N, ensuring the clamp springs clear of the workspace when air is removed.
Is the Airtac MTF Mini Cylinder MTF25X10U the Right Cylinder?
When sizing this 25 mm bore, compare its 153.6 N pull at 0.5 MPa against the smaller MTF20, which provides 93.4 N, or the larger MTF32, which delivers 266.8 N. Choose this model for spring-open, air-close jobs where losing air pressure safely drives the rod back out to the extended position. A minimum operating pressure of 0.2 MPa is required to overcome the spring. The U flat-end back cover suits flush mounting, and because this configuration omits the magnet, position sensing is not supported here.
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 MTF25X10U FAQ
This 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 internal return spring, with a maximum pressure of 1.0 MPa.
No, this specific SKU does not include a magnet, so it cannot support CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. The SUS304 stainless barrel resists mild corrosion, and the spring ensures the rod fails to the extended position on air loss.
