A ball bearing uses balls to maintain separation between the bearing races which is a type of rolling element bearing. Ball bearings are used to reduce rotational friction and support radial and axial loads. Ball bearings widely used to minimize friction and power loss, in instruments and machines. There are several types of ball bearings which fit specific needs. The most versatile ball bearings are the deep grove ones. The thrust ball bearings have no radical components and are adaptable to large thrust loads.
Selection of bearings compromises among many factors like performance requirements, nature of the application and cost. Click Here to view top brands of angular contact ball bearings.
