How do they get the balls in ball bearings so perfectly ...

The size of bearing balls has to be perfect, sometimes within millionths of an inch, so a few more operations are needed after heat-treating. The balls next go through a grinding operation. The same kind of machine is used, but this time the coolant contains an abrasive. The balls travel through the grooves again and get ground down and ...

Bearing noise?? | S-10 Forum

Yes i replaced front bearings inner, outer, and rear axle there is no slack on ethier side that is why i cant figure out where the noise is coming from. I also replaced both rotors and the drivers side ball joints because they where bad. But when i drive it sounds like a grinding noise that gets a little louder when i start applying the brakes.

An Overview of Bearing Vibration Analysis

As the bearing rotates, individual ball loads, hence elastic deflections at the rolling element raceway contacts, change to produce relative movement between the inner and outer rings. The movement takes the form of a locus which under radial load is two dimensional and contained in a radial plane whilst under misalignment it is three dimensional.
