An economical thin-walled copper based rolling bearing with high load-bearing capacity and wear resistance, made of CuSn8 bronze as the substrate. According to different lubrication conditions, we can provide two forms: diamond shaped oil holes and oil holes. Diamond shaped oil holes are used for grease lubrication, while through holes are used for fluid lubrication. This design ensures that a lubricating oil film can be established during the initial operation of the bearing, thus reducing the initial friction coefficient.
