Machine tool spindle bearings: The main raw materials are made of bearing steel forgings, which are processed by vacuum heat treatment to provide the wear resistance and service life of the bearings. The rolling elements are steel balls or ceramic balls. The cage generally adopts the outer ring-guided phenolic resin cage (TR), the rolling element-guided polyamide resin cage (TYN), and the rolling element-guided copper alloy cage (MY). Contact angles include C, AC, A5, E, A, B and other contact angles. Pairing methods are: GA, SU, DB, DT, DF, TBT, TFT, QBC, DBB, PBC, etc. Non-contact sealing ring products can be provided according to customer requirements. This series of products are widely used in CNC machine tools, machining center (CNC) machine tools, and other mechanical spindles with high rigidity requirements. The speed generally reaches between 1000 and 60000 rpm.
