The effects of thermal distortion due to viscous heating in the fluid film on the performance of a spiral-grooved, gas-lubricated thrust bearing are analyzed. A numerical example shows that considerable loss of load capacity is possible for bearings made of common structural materials. A simple criterion has been developed to check the importance of this type of thermal distortion.
