Airtac MTF Mini Cylinder MTF25X80CA
The AirTAC Airtac MTF Mini Cylinder MTF25X80CA 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 MTF25X80CA
Generating 153.6 N of pull force at 0.5 MPa (236 N at 0.7 MPa), this 25 mm bore cylinder is built for spring-open, air-close operations. As a JIS-standard round-body mini cylinder, its riveted SUS304 stainless barrel and aluminium covers create a shorter mounting envelope than a comparable ISO 6432 unit, saving valuable machine space while resisting mild washdown corrosion.
The internal spring constantly pushes the 10 mm rod out to its extended rest position, meaning a loss of air pressure safely drives the cylinder to the open state. Because this SKU lacks the -S magnet option, it cannot host CMSG, DMSG, or EMSG sensors. Air entering the 1/8" port retracts the rod, requiring a minimum 0.2 MPa to overcome the spring tension. Fixed TPU bumper pads absorb end-of-stroke impacts across the 80 mm travel.

Where the Airtac MTF Mini Cylinder MTF25X80CA Is Used
Belt Tensioning
Maintains constant tension on packaging belts using the 153.6 N pull force, retracting only when 1/8" port air pressure is applied.
Fail-Safe Gates
Holds access doors open by spring pressure; air retracts the 10 mm rod to close them, ensuring doors open automatically on air loss.
Clamp Retraction
Pulls workpiece clamps out of the way during tool changes, utilizing the 80 mm stroke and 0.2 MPa minimum pressure to overcome the spring.
Is the Airtac MTF Mini Cylinder MTF25X80CA the Right Cylinder?
When sizing this unit, evaluate your tension requirements against its 153.6 N pull at 0.5 MPa. A practical safe working load is roughly 92 N (about 60 percent of the rated pull), or an effective vertical lift of approximately 7.8 kg with a 2:1 safety margin. If your mechanism demands less force, step down to the MTF20 which yields 93.4 N at 0.5 MPa; for heavier pulling, the MTF32 provides 266.8 N at 0.5 MPa.
This single-acting pull design fits applications needing a fail-safe extended position, such as holding gates shut or tensioning belts. The CA back cover supplies a rear pivot point for angular alignment. Remember that without the -S magnet, position sensing is unavailable, and the fixed TPU bumpers regulate the 50-800 mm/s speed without adjustable air cushioning.
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 MTF25X80CA FAQ
This 25 mm bore cylinder generates 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 internal return spring, with a maximum pressure of 1.0 MPa and a proof pressure of 1.5 MPa.
The spring constantly extends the rod to its rest position, so air must enter the 1/8" port to pull it back; on air loss, it fails safely to the extended state. The CA back cover provides a pivot mount, and because this SKU lacks a -S magnet, it cannot support CMSG or DMSG sensors.
