    • Abstract
  • Manufacturing process of bearing rings made of powder by atomizing the stub bars and turning chips of bearing steel has been studied.The control and influence of oxygen contents in powder have also been investigated. Various mechanical and physical properties have been tested.The experiments on contact fatigue and bearing life have been conducted. The yield of material utilization was more than 70%.While the performance life of outer ring is 3 times longer than that calculated.This technology can be used for producing taper roller bearings.
