[0002] Bearings are components that fix and reduce the load friction coefficient during mechanical transmission. When other parts move relative to each other on the shaft, bearings are used to reduce the friction coefficient during power transmission and keep the center position of the shaft fixed. Rolling elements are an important component in bearings. The quality of rolling elements directly affects the overall performance of bearing products, so it is necessary to measure and detect the end face dimensions of tapered bearing rolling elements.
