King Bearings Race connecting rod bearings pMaxKote (Honda K20/K24A engines)

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

TRI-METAL STRUCTURE
Intermediate layer

The intermediate layer of a typical race bearing contains 2-3% tin, with hardness values of 90-95 HV. For a superior pMax Black™ intermediate layer, we increased the tin content to 4.5%, making it 22% harder (115 HV), with a load carrying capacity of 17,000 psi.

pMaxBlack™ Overlay

The overlay of a typical high performance bearing consists of a leaded alloy that contains 2-3% copper. It achieves a hardness level of 11 – 14 HV, and a maximum load capacity of 8,000-8,500 psi.

King’s pMaxBlack™ overlay is significantly stronger than conventional overlays due to its 5% copper content and an innovative nano-scaled hardening process.
