After rolling surface by ultra-precision machining of races, SKF bearings for improved performance in the following areas:
(1) improve the running accuracy of the bearing, study on reducing bearing vibration and noise test confirmed, FAG bearings rotate with increasing precision and reducing vibration and noise and rings the circular deviation significantly reduced has a lot to do.
(2) increase the carrying capacity of NSK bearings due to rings rolling surface bearing area of the century after superfinish greatly increased this to enhance the package create good conditions for the carrying capacity of the bearings. In addition, the bearing Raceway Superfinishing of rolling bearings with the exception of Crown, and enhancing the carrying capacity of the bearing.
(3) improve the lubrication of bearings, reducing wear and tear because of finishing rolling on the surface to form a uniform and delicate cross-textured, such cross-net lines on lubrication is very favorable. Make the surface easier to store oil, between the surface of the bearing rings when rolling to maintain a layer of oil, so as to avoid or reduce the wear of the bearings.
(4) reduce the fever of bearing that reflect a combined effect of ultra fine machining.
In short, Superfinishing has greatly enhanced the performance and service life of the bearings, because of Superfinishing dear there are so many features and effects, so increasingly favored by the finishing process of bearing rings.
