Deep Groove Ball Bearings with simple structure, are easy to use
and maintain. These bearing are mainly used to support radial load
and a certain amount of axial load. If enlarged the radial internal
clearance of these bearings, the bearings have the features of the
angular contact ball bearings and can support a heavier axial load.
These bearings have a less frictional resistance and a high
limiting speed, so can operate satisfactorily under high-speed
condition.
