Powder metallurgyr stepped upper bearing.
It is made of pre-alloyed powder in the bowl of the platform. Due to the specificity of the material, this product can reach the hardness of 38-45hrc only with sintering hardening, so it has better deformation control.As with the terraced bowl, this product also requires a patent license from the purchaser.
