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 regarding average tensile strength.
