Introduction
Angular contact ball bearings, also known as spindle ball bearings, consist of an inner ring, outer ring, ball, and a cage to contain and separate the ball. They are designed for combination radial and axial loading. Single-row bearings have high thrust capacity in one direction. Double-row Conrad bearings can accommodate thrust in both directions.
