Airtac MTF Mini Cylinder MTF25X100SCA
The AirTAC Airtac MTF Mini Cylinder MTF25X100SCA is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø25mm bore and 100mm 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 MTF25X100SCA
Delivering 153.6 N of net pull at 0.5 MPa, this single-acting spring-return cylinder uses air to retract the Ø10 mm rod and an internal spring to push it back out. Because the spring holds the rod extended at rest, the MTF25X100SCA fails safely to the open position on air loss, making it ideal for tensioning or air-close jobs. The 1/8 inch port feeds the retraction chamber, while fixed TPU bumper pads absorb end-of-stroke impacts across the 100 mm travel.
Built with a SUS304 stainless barrel and riveted aluminium covers, this JIS-standard round-body mini resists mild corrosion and washdown environments. It is shorter than an ISO 6432 cylinder for the same bore and stroke, saving valuable mounting length. The CA pivot back cover allows direct rear mounting, and the built-in magnet (-S) supports CMSG, DMSG, or EMSG position switches. With a safe working load around 92 N, it reliably holds or pulls about 7.8 kg with a 2:1 safety margin.

Where the Airtac MTF Mini Cylinder MTF25X100SCA Is Used
Tensioning Mechanisms
Uses the 153.6 N pull to draw back and tension belts or cables, releasing automatically to the extended rest position on air loss.
Fail-Safe Door Opening
Air retracts the rod to latch a door shut, while the internal spring forces it open and extended during a pneumatic power failure.
Light Retraction Tasks
Pulls loads vertically up to 7.8 kg with a 2:1 margin, relying on air to overcome the spring and draw the 10 mm rod inward.
Is the Airtac MTF Mini Cylinder MTF25X100SCA 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. Choose this model when your mechanism requires a spring-open, air-close action where loss of air pressure must drive the load to the extended position. Remember the system needs at least 0.2 MPa to overcome the spring force.
The CA rear pivot cover suits articulated rod-end loads, while the -S magnet option enables electronic or reed sensor tracking. For applications needing a held mid-stroke load, a double-acting MF cylinder with an external rod lock is required, as this spring-return unit cannot hold arbitrary positions.
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 MTF25X100SCA 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 return spring, with a maximum pressure of 1.0 MPa.
Air retracts the rod, and the spring extends it, meaning the cylinder fails to the extended position on air loss. The CA back cover provides a rear pivot mount, and the -S magnet allows CMSG or DMSG sensors to track position.
