mini ball bearing MR Series MR84ZZ
MR Series bearings have small friction coefficient, high limit speed, simple structure, low manufacturing cost, and relatively easy to achieve higher accuracy. It is the most widely used bearing in the machinery industry, which is used in precision instrument, low noise motor, automobile, motorcycle and general machinery industry. Mainly bear radial load, can also bear a certain amount of axial load. When the radial clearance of the bearing is increased, the performance of angular contact ball bearing can withstand the combined radial and axial load. When the speed is high and not suitable for using thrust bearings, it can be used to bear pure axial load. Compared with other types of bearings with the same size and specification of deep groove ball bearings, this kind of bearings has small friction coefficient and high limit speed. But not impact resistant, not suitable to bear heavy loads.
