King's MC Series features a bi-metal construction with a steel backing and strengthened aluminum alloy base layer, topped with an advanced K-340 nano-composite polymer coating. This factory-applied coating provides excellent anti-friction and wear resistance properties without adding any additional thickness to the bearing's precision wall dimensions. The lead-free design makes these bearings particularly well-suited for modern start-stop and hybrid engines that experience continuous metal-to-metal contact during operation.
