In view of the contact characteristics of angular contact ball bearings under the actual operating conditions, the model 7008C bearing was taken as the research object, and ANSYS Workbench was used to analyze the contact characteristics. The grid of the roller and the contact portion of the raceway was partialy refined, and analysis results was compared with the Hertz values to verify the applicability of the finite element method. The effect of raceway hardening on contact pressure was analyzed. The results show that raceway hardening can improve the equivalent stress and the maximum contact stress, but the effect is not obvious, and as the increaseing of the hardening depth, the stress increases slowly.
