What is the function of bearings?
2024-02-27
Function: Bearings are an important part of modern mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during movement, and ensure rotation accuracy.
What material is bearing steel?
2024-02-27
The hardness of bearing steel is relatively high, and this material is also relatively wear-resistant. Moreover, the chemical composition of bearing steel is very balanced, and the requirements for the distribution of various substances inside are very strict, especially the distribution of carbides.
How to maintain cylindrical roller bearings
2024-02-27
During the entire cleaning process of cylindrical roller bearings or after assembly, there is also a large inspection process to be carried out. Some of them are to inspect the quality of cylindrical roller bearings, and some are to inspect the quality indicators of finished bearings. These inspections are very necessary and strict.
