ABSTRACT:
In a double-row rolling bearing, there is a uniform relationship between a pre-load applied to the bearing and a pre-load gap formed by elastic transformation of rollers and some parts related to the rollers. Therefore, to measure the pre-load is equivalent to measure the pre-load gap. Then, a pre-load gap is measured at every row of the rollers, and measured values of the pre-load gaps are added together to thereby obtain an entire pre-load gap of the bearing.
