Mitigation of Micropitting in Wind Turbine Main Shaft Bearings

Sep 30, 2015· In recent years, increasing evidence of failures has been reported from spherical roller main bearings used in three-point mounting (TPM) drivetrains of wind turbines. One of the leading causes has been micropitting, a failure mode that is possibly overlooked by design, selection and life-prediction tools.

What Are Roller Bearings? | Types and Appliions

Browse All Bearings While roller bearings can handle higher loads than conventional ball bearings, their appliions are generally limited to low-speed operations. Many types of roller bearings are self-aligning, and are easily able to overcome misalignment and mounting issues — cutting down on maintenance, repair, and labor needs.
