Airtac MTF Mini Cylinder MTF20X80CA
The AirTAC Airtac MTF Mini Cylinder MTF20X80CA is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø20mm 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 MTF20X80CA
Delivering 93.4 N of net pull force at 0.5 MPa, the AirTAC MTF20X80CA is a JIS-standard round-body mini cylinder built for single-acting pull operation. An internal spring holds the 8 mm rod extended at rest, while supplying air to the 1/8 inch port retracts it. This fail-safe-to-extended behaviour makes the unit ideal for spring-open, air-close jobs. The SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown environments.
For the same 20 mm bore and 80 mm stroke, this riveted construction is shorter than a standard ISO 6432 cylinder, saving valuable mounting length. End-of-stroke deceleration is handled by fixed TPU bumper pads rather than an adjustable cushion. This specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG position sensors; specify the -S variant if switching is required. With a 0.5 MPa pull figure, the safe working load is roughly 56 N, translating to a vertical lift capacity of about 4.8 kg using a 2:1 safety margin.

Where the Airtac MTF Mini Cylinder MTF20X80CA Is Used
Tension Control
Pulls tensioning guides with a safe working load of 56 N, relying on air to retract while the spring maintains baseline tension.
Fail-Safe Closing
Holds a small gate open via spring force; air pressure pulls the 8 mm rod inward to close the valve during operation.
Light Retraction
Lifts or retracts light fixtures weighing up to 4.8 kg vertically, using the 93.4 N pull force at 0.5 MPa.
Is the Airtac MTF Mini Cylinder MTF20X80CA the Right Cylinder?
Select this 20 mm bore model when a tensioning or closing task requires approximately 56 N of safe working load at 0.5 MPa. If your application demands less force, note that 20 mm is the smallest available MTF bore. If you need greater pull strength, step up to the MTF25, which provides 153.6 N at 0.5 MPa. The internal spring requires a minimum operating pressure of 0.2 MPa to overcome and retract the rod.
This configuration features a CA rear pivot cover, making it suitable for pivoting mount setups. You can pair it with LB foot brackets, FA flanges, SDB pivot blocks, or TC trunnions. Because this base SKU has no magnet, it cannot support position sensing; choose an MTF20X80CA-S instead if you need CMSG, DMSG, or EMSG 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 MTF20X80CA FAQ
The net pull force is 93.4 N at 0.5 MPa and 146.1 N at 0.7 MPa. Because it is a single-acting pull cylinder with a spring return, it requires a minimum operating pressure of 0.2 MPa to overcome the spring and retract the rod.
No, this specific SKU does not include a magnet and cannot accept CMSG, DMSG, or EMSG switches. You must select the -S variant for sensing capabilities. Additionally, the spring ensures the rod fails to the extended position on air loss, and the SUS304 stainless barrel provides good washdown resistance.
