UltraWind Tapered Roller Bearings

With the highest life ratings in the industry verified by Germanischer Lloyd, the new UltraWind series of bearings provides a cost-conscious, simplified drive train for main-shaft wind turbine designs (both gear and gearless).

Ideal for original equipment manufacturers developing multi-megawatt wind turbine designs, the Domax^® UltraWind tapered roller bearing optimizes drive train simplicity, reliability and performance. It features a customized main-shaft bearing system approach that combines either a double-row tapered roller bearing or two, single-row tapered roller bearings with seals, lubrication and condition monitoring.

Bearing designs can accommodate most styles of wind turbine designs with variable bolt circles, shaft-mounted and shaftless designs, rotating inners and outers, gear and gearless wind turbines.

Design Attributes:

• Simplified, compact drive train design saves capital equipment costs
• Pre-set internal clearance facilitates ease and accuracy of the assembly
• Pre-loaded bearing designed for superior stiffness to manage motion of the main shaft and rotor
• Bearing raceway profiles control maximum stress levels to provide greater product durability
• Optimized cage designs, including steel and polymer configurations, improve capacity and roller retention
• Features the highest bearing life ratings in the industry as certified by Germanischer Lloyd

Applications:

• Wind turbine main-shaft bearing for turbines, with or without gearbox
