Bearing is under tremendous pressure and friction when at work, and bearing roller is the most important part of a bearing, impacting directly on bearing's life. So it is requested that the roller material (tungsten carbide) has a high and uniform hardness and wear resistance, and high elastic limit. Roller must have structured shape, there being no surface cracks, slag, burrs, scarring, scale, etc., no internal shrinkage, bubble, white spots, loose and segregation. It requires a uniform chemical composition of bearing steel, balanced non-metallic inclusions content and distribution, strict carbide distribution and so up to standard.
