Turbine components: bearings - Windpower Engineering & …

16/6/2015· In main-shaft bearings, modular wind-turbine designs commonly use spherical-roller bearings (SRB) units that are more than 1m in diameter. Designers often select single SRB designs, one supported by a single main bearing and two torque arms that carry gearbox reaction loads. At least two factors contribute to early failures in main-shaft bearings.
