Airtac MTF Mini Cylinder MTF20X15CA
The AirTAC Airtac MTF Mini Cylinder MTF20X15CA is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø20mm bore and 15mm 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 MTF20X15CA
Designed for spring-open, air-close tasks, the AirTAC MTF20X15CA is a JIS-standard round-body mini cylinder that operates via single-acting pull. A built-in spring holds the rod extended at rest, while supplying air to the 1/8" port retracts it. Because the cylinder fails to the extended position on air loss, it serves as an excellent fail-safe for mechanisms that must open during outages. The SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown environments.
In this 20 mm bore configuration, the unit generates a net pull force of 93.4 N at 0.5 MPa and 146.1 N at 0.7 MPa. The quoted force is already net of the internal spring, which requires a minimum 0.2 MPa operating pressure to overcome. For practical sizing, this yields a safe working load of roughly 56 N, or the ability to vertically lift and hold about 4.8 kg with a 2:1 safety margin. The 15 mm stroke is managed by fixed TPU bumper pads rather than an adjustable cushion. Note that this specific SKU lacks a magnet and cannot accept CMSG, DMSG, or EMSG sensors.

Where the Airtac MTF Mini Cylinder MTF20X15CA Is Used
Fail-Safe Vent Opening
Uses the internal spring to drive a 15 mm stroke vent open during air pressure loss, relying on the 93.4 N pull force at 0.5 MPa to draw it closed when pressurized.
Tensioning Mechanism
Maintains constant tension on a belt or cable in its extended rest state, with the 1/8" port supplying air to retract the 8 mm rod and release the load.
Spring-Return Diverter
Holds a diverter gate in the extended position by default, utilizing the CA pivot mount for smooth rotation when air pulls the mechanism back to change flow paths.
Is the Airtac MTF Mini Cylinder MTF20X15CA the Right Cylinder?
When sizing this 20 mm bore model, compare it directly against the MTF25, which raises the 0.5 MPa pull force to 153.6 N for heavier tensioning demands. If 93.4 N is excessive for your application, no smaller MTF bore exists, so you would need to reduce your operating pressure down to the 0.2 MPa floor. This single-acting pull design fits applications requiring a return-to-extended fail-safe, such as holding a gate open via spring tension and using air to pull it closed. Mounting is handled via the included CA rear pivot cover, and because this base unit lacks the -S magnet option, position sensing is not supported.
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 MTF20X15CA FAQ
This 20 mm bore cylinder provides a net pull force of 93.4 N at 0.5 MPa and 146.1 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.
The spring constantly extends the rod, meaning the cylinder fails to the extended position if air is lost. It cannot hold a mid-stroke load. Additionally, this SKU does not include a magnet, so CMSG, DMSG, or EMSG sensors cannot be installed.
