70mm Chrome Steel Bearing Ball For Machine Part 12mm Ball Bearing Balls



Chrome Steel Balls are used in the ball and roller bearing industry and for a variety of automobile applications. These Chrome Steel Balls have excellent surface quality. They offer superior wear resistance, high hardness and high load bearing capacity as a result of through-hardening.


GCr15 bearing steel is a high carbon chromium bearing steel with less alloy content,
good performance and the most widely used. After quenching and tempering,
it has high and uniform hardness, good wear resistance and high contact fatigue performance.
The steel has the characteristics of medium plasticity, low cutting performance, poor welding performance,
large sensitivity to white spot and temper brittleness
