Our produces mainly in angular contact ball bearings precision bearings class-based for P4 and P5, its high rotating accuracy and dimensional accuracy for high-speed operation. P4 class bearings are mainly used for precision and high-speed machine tools and precision measuring devices .     

Precision angular contact bearings, not only in use of refining bearing steel GCr15 inside and outside ball, but also according to customer requires using Si3N4 ceramic ball, ceramic ball have advantages such as low density, abrasion resistance and self-lubrication.
