Steel Ball Bearings

steel ball bearings

The ball-bearing industry has used SAE 52100 steel as a standard material since 1920. This is a high-carbon chromium steel which also contains small amounts of manganese and silicon.

A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races. ... Ball bearings tend to have lower load capacity for their size than other kinds of rolling-element bearings due to the smaller contact area between the balls and races.
