Deep groove ball bearings with low-friction seals on both sides have rolling elements made of silicon nitride (Si ₃ N ₄ ), which makes the bearings electrically insulating. The low-friction seals provide better sealing efficiency than shields and non-contact seals, which significantly extends bearing life, but they can still operate at the same speeds as shields. The silicon nitride elements not only provide protection against electrical current damage, but also, compared to bearings of the same size with steel rolling elements, provide improved bearing performance, extended bearing life, higher speed capacity, 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 harsh conditions and contaminated environments.

• Protected against electrical current damage
• Particularly suitable for use in harsh conditions and contaminated environments
