轴承几乎是每种机器的重要和主要部件之一。机器本身的质量主要也取决於轴承的质量。例如,在冶金工业中已获采用的上千种不同结构和性能的压延机械及上万种的各类辅助设备:铡刀式和盘式剪切机、矫直机、桥式吊车、搪床、板材捲筒、洗削机和刮削机、电动机及其他许多机械。 Bearings are almost one of the most important and major components of every machine. The quality of the machine itself also depends mainly on the quality of the bearings. For example, in the metallurgical industry has been used in thousands of different structures and properties of rolling machinery and tens of thousands of various types of auxiliary equipment: trowel and disc shears, straightening machine, bridge crane, boring machine, Plate reels, washing and scraping machines, motors and many other machines.
