King introduces the new solution for the aftermarket demand of superior service life and performance in modern engines. The new “MC” bearings were developed in the wake of ongoing internal combustion engine development, resulted in ever decreasing minimum oil film thickness values, higher cylinder pressures, temperatures and loads, smaller load carrying bearing surfaces, and lighter components. Additionally, “start/stop” technology produces more frequent mixed lubrication and metal-to-metal contact conditions . The new “MC” bearings feature a nano-composite polymer coating, known as K-340. This new developed polymer coating is designed for applying over relatively hard substrates: bronze, aluminum alloys, sputter overlay, and King silver overlay.

The Bi-Metal structure of the bearing (which consists of Steel back and a strengthened aluminum alloy) is applied with 5-10 microns of the mentioned polymer coating which by itself consists of solid lubricant and ceramic additives. The coating is part of the bearing manufacturing process. 

• MC Bearings’ Benefits:
• Excellent anti friction and wear resistance properties
• The polymer coating K-340 improves the bearing’s compatability
• High load capacity bearings with outstanding seizure resistance
• Especially suitable for start-stop and hybrid engines that operate constantly under metal-to-metal contact
