High Quality Deep Groove Ball Bearings (6312 NZR)

Deep groove ball bearings is the most common bearing. Its simple structure, easy to use. Mainly used to bear radial load, but increases when the radial bearing clearance, with certain properties of angular contact ball bearings can handle radial and axial joint load. They should not be used in a high speed thrust ball bearings, they can be used to bear the pure axial load. With the same size compared to other types of bearings, such bearings friction coefficient is small, extreme high speed. However, the impact of intolerance, unfit to bear heavy loads.
