Airtac MTF Mini Cylinder MTF25X80U
The AirTAC Airtac MTF Mini Cylinder MTF25X80U is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø25mm bore and 80mm 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 MTF25X80U
Delivering 153.6 N of net pull force at 0.5 MPa, this JIS-standard round-body mini cylinder uses an internal spring to keep the rod extended, while compressed air retracts it. The MTF25X80U features a SUS304 stainless barrel with riveted aluminium covers, yielding a shorter mounting envelope than an ISO 6432 unit of identical bore and stroke. Its 1/8 inch port and M10x1.25 male rod thread simplify pneumatic hookup.
Because the spring constantly drives the rod outward, the cylinder fails safely to the extended position if air pressure drops, making it perfect for spring-open and air-close mechanisms. This base SKU lacks a magnet and cannot host position sensors; adding the -S option enables CMSG, DMSG, or EMSG switches. With a practical safe working load of roughly 92 N, it reliably holds or pulls about 7.8 kg vertically.

Where the Airtac MTF Mini Cylinder MTF25X80U Is Used
Tensioning Systems
Uses the 153.6 N pull force at 0.5 MPa to maintain constant belt or web tension, releasing the load when air is applied.
Fail-Safe-Open Gates
Keeps barriers extended by spring force and pulls them closed via air, guaranteeing a safe open state during pressure loss.
Retracting Pushers
Holds a packaging pusher out of the way with spring pressure, using the 80 mm stroke to pull it back and clear the conveyor path.
Is the Airtac MTF Mini Cylinder MTF25X80U the Right Cylinder?
When sizing this 25 mm bore, compare its 153.6 N pull at 0.5 MPa against the MTF20, which yields 93.4 N, or the MTF32, which provides 266.8 N. Choose this model for tensioning, clamping, or fail-safe-open duties where air retracts the load and the spring pushes it back out. A minimum of 0.2 MPa operating pressure is required to overcome the internal spring.
The U flat-end rear cover suits tight axial spaces, and you can pair the body with LB foot, FA flange, SDB pivot, or TC trunnion brackets. Remember that this specific configuration has no magnet, so external mechanical limit verification is needed unless you switch to the -S variant.
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 MTF25X80U FAQ
This single-acting pull cylinder generates 153.6 N of pull force 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, and it uses a 1/8 inch air port.
No, this specific SKU does not include a magnet, so CMSG, DMSG, or EMSG switches cannot be used. You must select the -S variant for position sensing. The SUS304 stainless barrel and fixed TPU bumper pads provide reliable washdown resistance and end-of-stroke deceleration.
