The difference between precision spindle bearings and general rolling bearings needs to be realized in the following aspects: 1. The specifications and values ​​are different, and precision spindle bearings with strong precision grades have specification deviations (nominal diameter, diameter, ellipse, etc.) that are lower than the precision grades The specified value of the product should be small; 2. The specified value of the rotation accuracy is different. The precision spindle bearing with a strong precision grade has a higher rotation accuracy (inner radial runout, outer radial runout, end-to-raceway vibration, etc.) than the accuracy grade 3. The specified value of the surface shape and surface quality is different, the surface shape and surface quality of precision spindle bearings with strong precision grades (surface roughness of the raceway or section, ring deviation, groove Shape deviation, etc.) are stricter than the specified values ​​for products with low precision grades; 4. The raw materials of products with particularly strong precision grades are more beneficial than the material properties of products with general precision grades. Only when the torque is accurate can the rotation be stable! (http://)
