what are NSK angular contact ball bearings

Angular contact ball bearings have raceways in the inner and outer rings that are displaced with respect to each other in the direction of the bearing axis. This means that they are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads.
And   as essential components built into almost all machines involving rotation are able to help minimize friction and ensure smooth rotation, and come in various types depending on the application and place of use.
 which can accomodate moderate to heavy radial loads and low to moderate thrust loads in either direction come in all sizes, fit to meet the demands of the smallest industry applications like the miniature ball bearings in dental handpieces to the large rolling bearings found in steel mill applications. In addition ,they are ensured that the bearings are in the best possible condition, free of contamination, before and during operation while providing high level machining performance.
