Roller Bearings vs. Ball Bearings - What''s the Difference?

Jan 23, 2022· Ball bearings are described as having point contact; that is, each ball contacts the race in a very small patch – a point, in theory. Bearings are designed such that the slight deformation the ball makes as it rolls into and out of the load zone does not exceed the yield point of the material; the unloaded ball springs back to its original shape.

Ball bearing - Infogalactic: the planetary knowledge core

Often Conrad style ball bearings will exhibit contact ellipse trunion under axial load. What that means is that either the ID of the outer ring is large enough, or the OD of the inner ring is small enough, so as to reduce the area of contact between the balls and raceway.
