Precision bearing steel beads 8/9/10/11 / 12mm Features

• The appearance is precisely hydraulic, the structure is stable, and the polishing and polling is not lost.

• Good product foundation is good steel, we use the highest-end steel to ensure the functional standards of steel balls, and use the total GR15 bearing steel to be machined.

• High precision rating, small friction coefficient, polished, smooth surface smooth, high brightness

• High hardness, wear resistance, steel density, uniform load capacity, increase life, reduce replacement and damage

• High temperature resistance, high-end steel heat-resistant temperature, reduced the fragmentation and deformation of high-speed high temperature friction, is a precision steel ball worth more than high
