Case-carburized bearings have distinct advantages over through-hardened versions. Case studies presented here suggest properties to request in the specification for gearbox replacement bearings.
Vesconite says its bearings last up to 10x the life of bronze bushes, and they don’t swell so they work where nylon is unsuitable. May be the best material for dirty and poorly lubricated conditions.

Let’s start with the function of a pitch bearing, which is to allow for variable pitch position of the turbine blade and to transmit blade loads into the hub.
Schaeffler has optimized its spherical roller bearings for rotor main bearing supports with the objective of increasing the reliability, availability, and efficiency of wind turbines. The development of an asymmetrical spherical roller bearing represents yet another step towards more robustness. The bearing supports of the rotor shaft are of central significance in wind turbines. The
By introducing journal bearings into its gearboxes Winergy says it sets another milestone for wind turbine drive technology.
A physics based modeling approach can be used to establish a relationship between the forces acting on a component and the consumption of the component’s useful lifetime.
Timken Tapered Double Inner (TDI) Roller Bearing is designed to extend bearing life and improve system performance for three-point mount wind turbines.
Moventas has launched a kilowatt-class suite of life-extending services, Extra Life for kW. As older, kilowatt-class gearbox fleets age around the world, Moventas is ideally suited to extend the life of these components with its core technologies. Kilowatt-class gearbox fleet represent 12% of all gearbox fleets globally and 15% in Europe. Service for older gearboxes
Klüber Lubrication, a worldwide manufacturer of specialty lubricants, has announced the availability of Klübertherm HB 88-182.
