Bearing steel grit
Compared with traditional steel grit made by crushing steel shot, bearing steel grit has the following Features:
Raw Material
Bearing steel grit is made by Chromium bearing steel which has good harden ability due to its high content of Chromium.
Technology
Bearing steel grit is made by crushing the forged bearing steel directly which is free from casting defects.
Low wear
The forged state bearing steel grit with sharp edges has higher mechanical property than traditional cast steel grit with ball surfaces.
