Airtac MTF Mini Cylinder MTF25X150CA
The AirTAC Airtac MTF Mini Cylinder MTF25X150CA is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø25mm bore and 150mm 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 MTF25X150CA
Delivering 153.6 N of net pull at 0.5 MPa, this single-acting spring-return cylinder uses air to retract the rod and an internal spring to push it back out. It is a JIS-standard round-body mini built with a SUS304 stainless barrel and riveted aluminium covers, offering a shorter mounting envelope than an ISO 6432 unit of the same bore and stroke. The 1/8" port and Ø10 mm rod handle up to 150 mm of travel.
Because the spring holds the rod out at rest, the unit fails to the extended position on air loss, making it ideal for spring-open or air-close tasks. With a 0.2 MPa pressure floor needed to overcome the spring, it provides a safe working load of about 92 N. This base SKU lacks a magnet, so it cannot host CMSG, DMSG, or EMSG sensors without specifying the -S option. End-of-stroke deceleration relies on fixed TPU bumper pads.

Theoretical Output Force (Ø25mm)
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 153.6 N |

Where the Airtac MTF Mini Cylinder MTF25X150CA Is Used
Tensioning Mechanisms
Uses the 153.6 N air pull to tension belts or webs, relying on the spring to maintain a relaxed extended state during downtime.
Air-Close Valves
Air retracts the rod to shut a valve, while the internal spring automatically drives it back open if the air supply drops.
Fail-Safe Gates
Holds a gate open via spring force; applying air to the 1/8" port pulls the 150 mm stroke closed securely.
Is the Airtac MTF Mini Cylinder MTF25X150CA the Right Cylinder?
When sizing this 25 mm bore, compare its 153.6 N pull at 0.5 MPa against the smaller MTF20 at 93.4 N or the larger MTF32 at 266.8 N. Choose this model when a mechanism must fail to the extended position, such as a tensioning or gate-closing system. The CA rear pivot cover suits articulated rod-end loads, and you can pair it with LB foot, FA flange, or TC trunnion mounts. Operating pressure must stay between 0.2 and 1.0 MPa.
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 MTF25X150CA FAQ
It provides a net pull force of 153.6 N at 0.5 MPa and 236 N at 0.7 MPa. You must supply at least 0.2 MPa to overcome the return spring, with a maximum operating pressure of 1.0 MPa.
No, this specific SKU lacks the internal magnet required for sensing. You must select the -S variant to use CMSG, DMSG, or EMSG switches. The SUS304 stainless body and fixed TPU bumpers are standard.
