The shaft ring is a fixed bearing component, its main role is to reduce the bearing to bear the force and wear, while protecting the bearing and bearing seat. The classification of shaft rings is divided into circular shaft rings and square shaft rings according to their shapes and materials. The circular ring is suitable for radial loads, while the square ring is suitable for axial loads.
The washer is a component that fills or adjusts the gap between mechanical components, and its main role is to separate and reduce the transfer of force, adjust the gap between mechanical components, and prevent loosening and vibration. According to the different materials, gaskets can be divided into metal gaskets, rubber gaskets, plastic gaskets and so on. The metal washer is usually made of stainless steel material, which has the advantages of high temperature resistance and acid and alkali corrosion resistance. The rubber washer has the properties of sound insulation and shock resistance, and is widely used in mechanical equipment.
