The high precision bearing produced by the company mainly refers to the B7000 (original code 136000) series and 760000 series, mainly refers to the P4 and P5 accuracy grades, of which the B7000 series bearings are mainly used in the electric spindle, with high rotation accuracy and dimensional accuracy, suitable for high-speed operation; 760000 series bearings are mainly used in precision and high-speed machine tools and precision measuring devices; The inner and outer rings of Precision bearing are made of refined bearing steel GCr15, and other bearing materials can be used according to user requirements; The rolling elements of Precision bearing are made of refined bearing steel GCr15 and ceramic balls, the materials of ceramic balls are mainly Si3N4, ZrO2 and Al2O3, and the ceramic balls have the characteristics of low density, wear resistance and good self-lubrication, which are especially suitable for high-speed, high-precision and long-life bearings. Precision bearing's cages are mainly phenolic laminated tubing and reinforced nylon cages.
Precision bearing is used for multiple Matched stacks, and the specific fit type is referred to our sample - Matched stack Angular contact ball bearing.
