Precision

2019-02-24

For precision machinery such as machine tools, CNC lathes, index head, and precision rotary tables, precision is crucial. The accuracy of the final device is very strict, which requires its components have higher precision level. Crossed roller bearing and YRT turntable bearings are often used as precision machinery bearing because of high running accuracy.

Since the year 2012, BRS started to develop the precision machinery bearing products. Usually the slewing rings are turning finished, but BRS Bearing insist on grinding finishing even with higher cost, because grinding finishing improves bearings' precision and results in perfect matching of the rings and the elements.
