Ball bearings and roller bearings use small and rotating cylindrical balls made from metal, which separate the component parts and reduce the degree of operational friction. Linear bearings allow free movement in one direction or another and use pad, roller or bushing systems.

For ball bearings with shaft diameter less than 2 inches, the interference fit between shaft and inner ring should not be more than 0.001", which means cold mounting with an arbor press or dead blow hammer with a mounting sleeve against the inner ring of the bearing works fine and heating is not normally needed to prevent damage to the shaft ...

Misalignment – Ball or Roller Path; When one side of a bearing is misaligned in relation to the other, the ball or roller path will run from one side of the race to the other around one-half of the circumference on the non-rotating ring. The rotating ring will have a wide roller path. This can result in high temperature and destroy the lubricant

Avoid using cock ring substitutes; rubber bands, binder clips, and vices, for example, cause too much constriction. Cock rings fit over the shaft and sometimes the shaft and the testicles/scrotum when a man is not erect, or semi-erect. Ball by ball, the testicles go through, then the penis shaft dives in head first through the remaining ring space.

When a bearing's inner race is mounted on a shaft with an interference fit, some expansion of the inner race O.D. (roller path or ball groove) occurs. This has the effect of reducing the manufactured or "bench" internal clearance of the bearing. This is a very important consideration when designing a machine.

In the case of ball bearings, the bearing has inner and outer races and a set of balls. Each race is a ring with a groove where the balls rest. The groove is usually shaped so the ball is a slightly loose fit in the groove. Thus, in principle, the ball contacts each race at a single point.

In the case of small non-separable ball bearings, hold the bearing horizontally in one hand, and then rotate the outer ring to confirm that it turns smoothly. Separable bearings such as tapered roller bearings may be checked by individually examining their rolling elements and the outer ring raceway.
