Hybrid ceramic single row deep groove ball bearings for wind turbine generators are designed to meet the application requirements for electric generators in larger wind turbines. They have rings made of bearing steel and rolling elements made of bearing grade silicon nitride, which make the bearings electrically insulating. The ceramic rolling elements not only provide protection from electric current damage but also, when compared to same-sized bearings with steel rolling elements, provide enhanced bearing performance, extended bearing service life, higher speed capability, high wear-resistance, high bearing stiffness, reduced risk of smearing and false brinelling, and less sensitivity to temperature gradients, making them suitable for use in dificult conditions and contaminated environments.
