Crankshaft bearing set for the Nissan RB26DETT
Below a lot of technical data about what makes these bearings stronger or better than standard bearings. King bearings are equipped with DLC coating from the F1 (Koenigsegg also uses King bearings for example) which ensures that if your S54 squeezes the oil out between the bearings because it can build up too much pressure at higher revs, it is still lubricated by a very hard but also extremely smooth layer.
King Factory Applied Nano Composite Polymer Coating - 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 improves wear resistance without changing the bearing's original precision wall thickness dimension.
King's pMaxKote™ is a new approach to coated bearings. It has been proven to protect bearings during metal-to-metal contact, as well as against the erosive effects of cavitation. It contains ceramic nano-composite particles that function as a fourth layer that provides superior protection.
pMaxKote™ enhances the following benefits of King XP race bearings:
• Superior attack resistance
• Superior cavitation resistance
• Superior wear resistance
• Superior oil loss protection
pMaxBlack™ tri-metal structure
Intermediate layer
The interlayer of a typical bearing contains 2-3% tin, with hardness values of 90-95 HV. For a superior pMaxBlack™ interlayer, we increased the tin content to 4.5%, making it 22% harder at 115 HV, with a load rating of 17,000 psi.
pMaxBlack™ overlay
The overlay of a typical high-performance bearing consists of a leaded alloy containing 2-3% copper. It achieves a hardness rating of 11-14 HV and a maximum load capacity of 8,000-8,500 psi.
King's pMax Black™ overlay is significantly stronger than conventional overlays due to its 5% copper content and an innovative nanoscale hardening process.
