*For expansion bearings, this dimension can increase by the corresponding value in table VIII on page I-69.
One expansion unit is to be used in conjunction with one non-expansion unit for applications using an adapter lock unit
Failure to utilize one expansion and one non-expansion unit is likely to result in reduced bearing performance.
