Personal History
The broadly utilized ball bearing to support outspread load is Deep Groove Ball Bearing' or 'Conrad-bearing'. They are basically intended to support high radial load and moderate thrust load. They have profound raceways that are consistent (i.e. there are no openings or breaks) over the greater part of the ring boundaries. This sort of development allows the bearings to bolster generally high push stack in either bearing. A ball bearing fundamentally intended to bolster spiral load can likewise bolster high push load; because only few balls convey the outspread load, though every one of the balls can withstand the thrust load.
