Bearing materials include steel for bearing rings and rolling elements, as well as steel sheet, steel, copper alloy and synthetic resins for cages.
These bearing materials should possess the following characteristics :
Bearing rings Rolling elements
- High elasticity, durable under high partial contact stress.
- High strength against rolling contact fatigue due to large repetitive contact load.
- Strong hardness
Bearing rings Rolling elements Cages
- High abrasion resistance
- High toughness against impact load
- Excellent dimensional stability
