The Importance of Thrust Bearing Surface Finish While in operation, a properly designed fluid-film bearing delivered an adequate supply of cool, clean, lubricant experiences no wear. The rotor and bearing surfaces are completely separated by a lubricating film. However, some bearing wear occurs during transitional periods such as unit start-ups, shutdowns, and rotational reverses. Click here to read more.
