Bearing the numbermeaning

This kind of ball bearing has a spherical outer race, allowing the axis of the bearing to “wander around”.  This is important because misalignment is one of the big causes of bearing failure.

Bearing numberList

Axial cylinder roller bearings comprise axial cylinder roller and cage assemblies and shaft and housing locating washers.  The bearings have particularly small axial section height, have high load carry capacity and high rigidity and can support axial forces in one direction

The 3rd and 4th Numbers of the Bearing Number Relate to the Bore Size of the Bearing, Numbers 00 to 03 have a Designation Bore Size Depending on the Number.

The 2nd Number Relates the Bearing Series, which Reflects the Robustness of the Bearing.  As you go Up the Scale Below from 9 to 4 the Inner and Outer Race Thickness will usually Increase along with the Ball Size, this will be to Cope with Extra Load.

Specific geometry of angular contact bearing raceways ans shoulders creates ball contact angles that support higher axial loads
