2304 Self Aligning Bearing | AXIS 2304 Bearing - 20x52x21

This 2304 self-aligning bearing is a high-performance 20x52x21 ball bearing manufactured to an elevated standard by AXIS. What sets this 2304 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 2304 bearing features raceways that are precision honed to a superb finish.

Self-aligning 2304 bearings are designed with two rows of balls; the inner raceway consists of two grooves to support each row of balls, while the outer raceway has only one groove for both sets of balls. This design creates a self-centering effect with flexibility between the two rings; the end result is a 2304 bearing that is insensitive to angular misalignment. Making this type of bearing ideal in applications that are prone to shaft deflection and misalignments.
