Hybrid single row deep groove ball bearings with seals on both sides have rings made of bearing steel and rolling elements made of bearing grade silicon nitride (Si3N4), which provide electrical insulation of the bearings. The integrated seals can significantly increase the service life of the bearing by keeping the lubricant inside and preventing contaminants from entering the bearing from the environment. Silicon nitride elements not only protect against electrical damage, but also, compared to bearings of the same size with steel rolling elements, provide improved performance and extended bearing life, higher operating speeds, high bearing wear resistance and rigidity, reduced risk of scuffing and false brinelling, and reduced sensitivity to temperature changes, making them suitable for use in difficult conditions and contaminated environments.
