Through precise processing, various types of rolling bearings can be achieved high accuracy requirements, SKF high precision bearings is most commonly used in angular contact ball bearings, and high accuracy and high rigidity requirements for metal-cutting machine tool spindle, double row cylindrical roller bearings are not small either, and secondly the tapered roller bearings.
　　Currently, due to the development of technology for SKF bearings, precision bearings at all levels international level mostly in the standard value of the actual finished error one-second the following, for example, SKF ball bearings for machine tool for 0.3 μ m, and 0.25 for computers used in μ m.
　　In General, customers for precision selection of SKF bearings, first select from the three types mentioned above. And that, even in these three types, and not each specification precision products, must also be at the House bearing samples to find the company or production plants, or bearing to the Sales Department for information. Typically, the P4 precision SKF bearings are easier to buy, P2-level precision SKF bearings are mostly needed by special order made. Production of precision products for the first time to manufacture new products.
　　Ways to get high precision spindle supported, in principle, can be boiled down to the following several points:
　　(1) selection of SKF bearings with higher accuracy and technology to improve its accuracy;
　　(2) pay attention to applications, for example with error cancellation method for improving the precision, less interference method to reduce deformation of the Raceway, adjust the clearance method to improve positioning precision and rotation accuracy;
　　(3) eliminate the cause factors affecting the loss of precision of SKF bearings.
