This 5303-ZZ Bearing is a high-precision premium shielded double-row angular contact ball bearing made to ABEC 3 precision standards from AXIS. What sets this 5303-ZZ bearing apart from others is the ABEC 3 precision standard that this bearing is made to, the grade 10-balls used, and the superb electric motor quality rating (EMQ). ABEC 3 means that the bearing itself has a micron deviation from a nominal of 20.000mm of -8 micrometers. The standard ABEC 1 precision standard that almost all ball bearings are made to today has a deviation of -10 micrometers. In simple terms, the more precision a bearing is, the better it will perform in any given application. The grade 10 balls within this bearing are typically only found within ABEC 5 or higher bearings because of their more true roundness and precision. The balls within a bearing share the load capacity, so this also increases the working life versus the standard grade 25 balls used in other brands. The electric motor quality rating means that the bearing must operate at an extremely low noise level with minimal to no vibration. To achieve this, the 5303-ZZ bearing features raceways that are precision honed to a superb finish.

More specifically, 5303-ZZ double row shielded ball bearings possess higher radial and axial load capacities in either direction when compared to single-row ball bearings, they are found within a broad range of industrial and agricultural applications. The metal shields that are located on both sides of the bearing prevent unwanted debris from entering the bearing and also hold in the bearing grease.
