small size ball bearing hardness
Bearing basics | SKF | SKF
The materials from which bearing components are made, determine, to a large extent, the performance and reliability of the bearing. For the bearing rings and rolling elements, typical considerations include hardness, fatigue resistance in the rolling contact area, under clean or contaminated lubriion conditions, and the dimensional stability of the bearing components.
