  • Bearing element having polymeric coating and method of application of polymeric coating to bearing element for electrical insulation
    Patent number: 11708859
    Abstract: A method of providing electrical insulation for at least one portion of a bearing element is disclosed herein. The method includes electrostatically spraying a polymer coating to the at least one portion of the bearing element, and the polymer coating comprises a thermoset epoxy coating or a self-adhering nylon powder coating. The bearing element can be grounded during the electrostatic spraying. The method includes heating the polymer coating in an oven at a temperature less than or equal to 220° C. for a predetermined time, such that after removal from the oven, the polymer coating has a porosity of less than 10%. The coated bearing element has a resistance of at least 50 M? resistance under dry conditions and 10 M? resistance under wet conditions.
