pMaxKote™
King Factory Applied Nano-composite Polymer Coating – With No Added Thickness!
King’s new pMaxKote™ is a nano-composite polymer coating. It is applied over the pMaxBlack™ overlay at the King factory as part of the bearing manufacturing process. It enhances wear resistance without changing the bearing’s original precision wall thickness dimension.

King’s pMaxKote™ is a new approach to coated bearings. It has proven to protect bearings during metal-to-metal contact, as well as from the erosive effects of cavitation. It contains ceramic nano-composite particles that function as a fourth layer that provides superior build protection.

pMaxKote™ enhances the following benefits of King XP race bearings:

• Superior seizure resistance

• Superior cavitation resistance

• Superior wear resistance

• Superior protection against oil starvation
