Airtac MTF Mini Cylinder MTF20X60SU
The AirTAC Airtac MTF Mini Cylinder MTF20X60SU is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø20mm bore and 60mm 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 MTF20X60SU
Designed for spring-open, air-close tasks, the AirTAC MTF20X60SU uses an internal spring to keep the rod extended, relying on 1/8" port air pressure to pull the 8mm rod back in. It yields a net pull force of 93.4N at 0.5MPa, translating to a safe working load of roughly 56N or a 4.8kg vertical lift capacity with a 2:1 margin.
This JIS-standard round-body mini cylinder features a SUS304 stainless barrel and riveted aluminium covers, delivering a shorter mounting envelope than an ISO 6432 unit. The U flat-end back cover simplifies direct rear mounting, while the -S magnet enables CMSG, DMSG, or EMSG sensors for position tracking.

Where the Airtac MTF Mini Cylinder MTF20X60SU Is Used
Tension Mechanisms
Applies up to 93.4N of pulling force at 0.5MPa to maintain belt or cable tension, automatically snapping back to the extended rest position if air pressure drops.
Fail-Safe-Open Gates
Holds a light 20mm bore gate open via spring force; air retracts the rod to close it, ensuring the barrier extends outward during an air loss event.
Retract-to-Reset Pushers
Uses air to pull an 8mm rod back and reset a packaging deflector, with the spring returning the mechanism to its extended ready state between cycles.
Is the Airtac MTF Mini Cylinder MTF20X60SU the Right Cylinder?
When sizing this 20mm bore unit, step up to the MTF25 if you need more pull (153.6N at 0.5MPa); there is no smaller MTF bore. The MTF20X60SU fits tensioning or fail-safe-open designs where the spring holds the load out, and air retracts it. Maintain at least 0.2MPa operating pressure to overcome the spring.
Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion brackets. Fixed TPU bumper pads absorb end-of-stroke impact across the 50-800mm/s speed range.
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 MTF20X60SU FAQ
This 20mm bore cylinder provides a net pull force of 93.4N at 0.5MPa and 146.1N at 0.7MPa. It requires a minimum operating pressure of 0.2MPa to overcome the internal return spring and retract the rod via its 1/8" port.
The spring constantly drives the rod to the extended position, meaning the cylinder fails to extended upon air loss. It cannot hold an arbitrary mid-stroke load; for that, use a double-acting MF cylinder with an external rod lock. The -S magnet allows CMSG, DMSG, or EMSG sensors to track position.
