Bearing and gearbox failures: Challenge to wind turbines - …

KEY CONCEPTS • In 2019, 7.3% of U.S. energy demand was met by wind energy, with that percentage predicted to increase to 20% by 2030. • Reducing premature bearing failures in wind turbines will make wind energy more cost competitive and reliable. • White etching cracks (WECs) and other bearing failure modes are being studied to identify causes and preventions.

Mounted Bearing Locking Collar: Which Is Best? - Baart Group

The concentric collar is the first high-speed applicable locking style. The collar goes all the way around the outside of the mounted bearing’s inner, segmented, ring. As the collar clamps down, it provides an even distribution of force to all 360° of the shaft. Concentric collar shaft locks do an excellent job keeping everything balanced
