Difference between bearing steel and carbon steel:
1). Material cost: bearing steel is about 50% higher;
2). Life span: bearings made of bearing steel last longer than those made of carbon steel;
3). Wear-resisting property: bearing steel has very strong wear ability, while carbon steel is generally heat-treated on its surface and not hard enough;
4). Bearing steel has very good elasticity, fatigue strength, strong anti-friction and loading capacity, while carbon steel does have those desirable advantage points;
5). Bearings made of bearing steel can run very smoothly without noise, while those made carbon steel have mechanical noise in rolling.
