Airtac MTF Mini Cylinder MTF25X50SCA
The AirTAC Airtac MTF Mini Cylinder MTF25X50SCA is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø25mm bore and 50mm 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 MTF25X50SCA
Delivering a net pull force of 153.6 N at 0.5 MPa, this JIS-standard round-body mini cylinder is engineered for single-acting pull operations. The internal spring normally holds the rod extended, while supplying air to the 1/8 inch port retracts it. Because the spring drives the rod out upon air loss, the MTF25X50SCA provides a fail-safe extended state for tensioning or air-close tasks.
The SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown environments. For the same bore and stroke, this compact body is shorter than an ISO 6432 cylinder, saving valuable mounting length. The fixed TPU bumper pads absorb end-of-stroke impact across the 50 mm travel. With a 0.5 MPa pull force of 153.6 N, the computed safe working load is about 92 N, yielding a vertical lift capacity of roughly 7.8 kg with a 2:1 margin.

Where the Airtac MTF Mini Cylinder MTF25X50SCA Is Used
Tensioning Mechanisms
Uses the 153.6 N pull force to draw back a belt or cable, releasing tension automatically when air pressure drops.
Air-Close Valves
Keeps the valve open via spring force and pulls the 10 mm rod inward to close it, ensuring the valve opens if the air supply fails.
Rejector Arms
Holds the arm extended by default and retracts it pneumatically to clear a 7.8 kg package off a conveyor line.
Is the Airtac MTF Mini Cylinder MTF25X50SCA the Right Cylinder?
When sizing this 25 mm bore, compare its 153.6 N pull force at 0.5 MPa against adjacent bores: 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 a mechanism must fail to the extended position, such as a spring-open clamp, requiring 0.2 MPa minimum pressure to overcome the spring.
This SKU includes the -S magnet for CMSG, DMSG, or EMSG sensors, and features a CA back cover for rear pivot mounting. The male M10x1.25 rod thread handles the load, and the fixed TPU bumpers manage speeds from 50 to 800 mm/s.
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 MTF25X50SCA FAQ
The net pull force is 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 spring, with a maximum pressure of 1.0 MPa.
The spring constantly extends the rod, and air pressure retracts it. On air loss, the spring pushes the rod to the extended position; it will not hold a mid-stroke load. The -S magnet allows position sensing.
