Zealous Bearings stands out as the industry's premier choice, renowned for its exceptional speed, durability, and innovative design. Featuring bearing shields on both sides, these bearings effectively block out dirt and debris, ensuring smooth and consistent performance. The secret lies in their unique lubricant, which utilizes a nanoceramic compound to fill in deformations within the bearings, reducing friction and heat buildup. This micro coating, boasting 5 times the hardness of the host alloy, forms a molecular bond with the metal, eliminating friction over time and resulting in a near frictionless surface. With a coefficient of friction of just 0.003%, Zealous Bearings offer unparalleled performance and reliability. Upgrade your setup and experience the difference with Zealous Bearings today.
