Bearings are an essential component in modern mechanical equipment, primarily functioning to support rotating parts, reduce friction during motion, and ensure precise rotational accuracy. Based on the different friction characteristics of their moving elements, bearings can be classified into two major categories: rolling bearings and sliding bearings. While rolling bearings have been standardized and serialized, they tend to have larger radial dimensions, higher vibration levels, and greater noise compared to sliding bearings—and they also come at a higher price.
