Wear-resistant bearings for wind-energy applications are designed to reduce life-limiting wear problems including micropitting on main shaft spherical roller bearings and micropitting, smearing and brittle flaking on wind turbine gearbox bearings. Wear-resistant bearings also provide up to 3.5 times greater L10 life for main-shaft and gearbox bearings.
Design Attributes
In-house developed wear-resistant coating and bearing materials help defeat the adhesive wear mechanisms that cause smearing, micropitting and fretting
The unique coating forms barriers to adhesive wear during brief periods of lube starvation
Specially-designed rollers remove shoulders around debris craters on raceways and reduce surface roughness on the ring raceways
Rollers polish ring raceways which reduces Ra (surface finish), increases λ (lambda), reduces rolling torque and increases efficiency
Applications
