Timken® 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 Timken® 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.
