Many mechanical equipment have large and small, a variety of bearings, and the main role of bearings in addition to fixed, but also in the process of mechanical operation to reduce friction, to ensure its accuracy. What is the difference between rolling bearing and sliding bearing? To this end, Chen

Bearing cage, also known as bearing retainer, is one of the main parts of bearing. Its function is to wrap and isolate the rolling element and move with it, and it usually has the function of guiding the rolling element. But in the process of bearing rotation, the cage's free vibration and its impac

Several anti-rust methods for slewing bearingsThe slewing bearing is an important part of many mechanical equipment. It is a kind of metal product. If it is not used for a long time, or if it is improperly maintained, it is easy to rust, which will reduce its performance and even be scrapped. Theref

As an additional process of slewing bearing gear processing, this article discusses the influence of gear quenching and tooth surface non-quenching on slewing bearing.The material of slewing bearing is generally 50Mn and 42CrMo. The 50Mn material is usually normalized and the hardness is about HB180
