Timken® UltraWind Tapered Roller Bearings

With the highest life ratings in the industry verified by Germanischer Lloyd, Timken® UltraWind tapered roller bearings provide a simplified drive train for main-shaft wind turbine designs (both gear and gearless). These bearings feature 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.
