Material selection of rolling bearing ring and rolling element
Rolling bearings are a type of bearing that we often use in our daily lives. Rolling bearings are mainly composed of an outer ring, an inner ring, rolling elements and a cage. For the rings and rolling elements of rolling bearings , the choice of material is very important. These two components can determine the performance and use of rolling bearings. We can choose the materials that meet the needs of rolling bearing rings and rolling elements. 1. High carbon chromium bearing steel Most bearing rings and rolling elements are made of special steel. The rings and rolling elements are made of high carbon chromium bearing steel (GCr15, GCr15SiMn, ZGCr15 and ZGCr15SiMn), and the hardness of the parts is as follows: The rings and rollers made of GCr15 and ZGCr15 materials are HRC61~65, and the steel balls are HRC62~66; The rings and rollers made of GCr15SiMn and ZGCr15SiMn materials are HRC60~64, and the steel balls are HRC60~66. Bearings made of high carbon ...
