Zys Smooth Polished Precision Bearing Balls steel balls 0.8MM with Finest Quality Alloy Steel
GCr15 steel balls are one of the commonly used steel grades for bearing rolling elements and sleeve drawings. The bearing ball has excellent comprehensive performance, good cutting performance after annealing, high hardness and uniformity after quenching and tempering, high wear resistance and contact fatigue strength, and good thermal performance. GCr15 steel is the most used and produced in high carbon chromium bearing steel material and is widely used in the world.
ZGCr15 is electroslag dissolved steel, which has fewer impurities and better properties than GCr15.
Application: Suitable for machine tool spindle bearing, high-speed rolling mill bearing, machine tool bearing.
