Introduction Since the invention of stainless steel at the beginning of the 20th century, the stainless steel has combined the image of contemporary materials and the excellence remains of construction uses [1].
It has good corrosion resistance for various environments and is also one of the highest strength construction materials. 0Cr17Ni7Al belongs to semi-austenitic precipitation hardening stainless steels and is modified on the base of 18-8Cr-Ni stainless steel.

All the materials are assumed to be isotropic, linear and elastic. (3) The lubricating oil in the bearing can be regarded as the incompressible laminar steady flow.
The material of the hollow coaxial is low alloy cast steel.
Therefore, the deformation of the hollow coaxial with the same thickness made from different materials is different in the same loading conditions.
So selecting the materials with larger elastic modulus can improve the running stability of bearing.
