King Bearings – Engine Bearing specialist

What is the difference between pMax Black™ vs. pMaxKote™?

pMaxBlack is a surface hardened  lead tin copper overlay that is electroplated onto a copper alloy substrate making up the third layer of a King XP bearing.  pMaxBlack also has additional  copper content, when compared to regular tri-metal  bearing overlays,  increasing  the fatigue strength to handle loads up to 10,200 psi.

pMaxKote is a factory applied nano composite polymer coating formulated especially for pMaxBlack overlays. pMaxKote provides excellent wear and cavitation resistance while protecting bearing surfaces during periods of oil starvation and minimum oil film thickness.  pMaxKote is applied with no added wall thickness therefore not altering oil clearances.
