Selected high quality bearing steel/good rigidity/bearing steel has high hardness and abrasion resistance and uniformity, high elasticity limit. This is one of the most demanding steel types of all steel
The surface of the steel ball is exquisite, no burr, smooth and flat, can withstand pressure without deformation / high temperature resistance/sturdy and
Hardness may exceed HRC60 / Concentric tolerance is about 0.001mm
The steel ball bearings can be widely used in bicycles wheel, auto parts, bearings, casters, drawer slides, DIY projects, door locks, and a variety of small machinery applications, including skateboard wheels, inline skates, and electric motors, instrumentation and more.
