Self Aligning Ball Bearings - an overview | ScienceDirect

The experimental system, shown in Fig. (8), consisted of a 20 mm diameter flexible shaft, which was 1.0 meter long. The shaft was mounted on two self-aligning ball-bearings and it was driven by a 20 Nm rated AC brushless motor capable of running up to 4500 RPM.A flexible disk was mounted on the other end of the shaft.

WHY THE BEARINGS GET FLAT SPOTS

When you begin to feel the effect of flat spots on the bearings, the area on each bearing where the ball touches is about 1/32 inch in diameter (.03 inch). The total wear area of the three bearings is about .002 square inches – not very big, but the ratio of the ball to the bearings has dropped from 3 million to 1 down to about 3 thousand to 1.
