Airtac MTF Mini Cylinder MTF25X150SCA
The AirTAC Airtac MTF Mini Cylinder MTF25X150SCA 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 MTF25X150SCA
Generating 153.6 N of pull force at 0.5 MPa, this AirTAC MTF25X150SCA mini cylinder is built for single-acting tension and return-to-extended fail-safe tasks. The internal spring constantly pushes the rod out to its maximum 150 mm stroke, while compressed air entering the 1/8" port retracts the piston. Because the spring actively holds the rod out, any loss of air pressure automatically drives the mechanism to the extended position rather than trapping it mid-stroke.
The riveted round-body construction pairs a SUS304 stainless steel barrel with aluminium covers, offering a shorter overall mounting length than a comparable ISO 6432 unit while resisting mild washdown corrosion. It relies on fixed TPU bumper pads for end-of-stroke deceleration across its 50-800 mm/s speed range. For position feedback, the integrated -S magnet supports CMSG, DMSG, and EMSG switches, and the rear CA pivot cover simplifies articulated rod-end mounting. Based on the 0.5 MPa rating, the safe working load is approximately 92 N, translating to a vertical lift capacity of about 7.8 kg with a 2:1 safety margin.

Where the Airtac MTF Mini Cylinder MTF25X150SCA Is Used
Tensioning Systems
Uses the 153.6 N pneumatic pull to tension belts or webs, with the internal spring automatically relaxing the load to a safe extended state upon air loss.
Fail-Safe Open Valves
Holds a process valve open via spring force; applying air to the 1/8" port pulls the 150 mm stroke closed, ensuring the pipeline opens if the air supply drops.
Package Rejectors
Retracts a diverter arm using compressed air to push items off a belt, letting the spring snap the arm back to its extended rest position for the next cycle.
Is the Airtac MTF Mini Cylinder MTF25X150SCA the Right Cylinder?
When sizing this 25 mm bore, compare its 153.6 N pull at 0.5 MPa against the smaller MTF20, which yields 93.4 N, or the larger MTF32, which provides 266.8 N. This model fits spring-open/air-close mechanisms where air actively pulls the load and the spring ensures a fail-safe extended state. A minimum operating pressure of 0.2 MPa is required to overcome the internal spring before any retraction can begin.
The rear CA pivot cover is ideal for applications requiring angular alignment during the stroke. To utilize the CMSG, DMSG, or EMSG sensor suite, ensure you specify the -S magnet option, as standard SKUs cannot accept position switches.
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 MTF25X150SCA FAQ
This single-acting 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 limit of 1.0 MPa.
The internal spring constantly extends the rod to its resting position. If air pressure is lost, the cylinder fails safely to the fully extended state; it cannot hold a load mid-stroke. The SUS304 stainless barrel provides mild corrosion resistance, and the -S magnet allows CMSG or DMSG sensors to track position.
