ATA Series

Higher model of AT series (Advanced model)

Has 2x the bush-roller wear resistance & 1.5x the pin-bush wear resistance of AT Series, along with 1.2x the maximum allowable load. ATA Series chains are available with R and F rollers from RF08-RF36 size only.

Operating temperature range: -20°C* to 200°C

Contact a Tsubaki representative when using below -20°C.

2. Features

ATA Series has better wear resistance and a higher maximum allowable load than AT Series.

1.5x better pin-bush wear resistance

2x bush-roller wear resistance

1.2x maximum allowable load

*Maximum allowable load is the numerical value set by fatigue limit, allowable surface pressure, etc.

3. Table of Sizes and Strength

  • Maximum allowable load is a value calculated based on Tsubaki in-house standards and is calculated strength. As long as there are no other constraints, maximum allowable load is used in selecting large size conveyor chain. This value will differ by manufacturer and is not a guaranteed value.
  • Contact a Tsubaki representative for average tensile strength.
