UltraWind bearings provide a tapered roller bearings with integrated seals, lubrication, and condition monitoring. With the highest life ratings in the industry certified by Germanischer Lloyd, the UltraWind Series provides a cost-conscious, simplified drivetrain for main-shaft wind turbine designs (gear and gearless). For multi-megawatt turbines, the pre-loaded tapered roller bearing is better suited than others to address concerns such as stresses, rigidity, and load management that affect bearing life and reliability. The UltraWind series provides superior stiffness to manage motion of the main shaft and rotor. Its bearing raceway profiles control maximum stress levels for enhanced durability, and the cage is optimized for capacity and roller retention, including both steel and polymer configurations. Hence, the bearings are part of an integrated main-shaft for specific operating requirements. In collaboration with customers, manufacturer Timken takes into account the total operation of the bearing and power-drive system to optimize the sustainable life of the equipment.
