King's TechLab – Exceed and Excel

TechLab is our starting point for exploring and developing new technologies. It’s where our new products and features are designed, tested and validated.

Our TechLab R&D culture focuses on constant analysis of what can be done to support ever increasing race engine loads, and how to improve bearing durability.

One of those technologies is pMax-Black™.

pMaxBlack™ combines a unique tri-metal structure with advanced surface processes to deliver superior load capacity.

pMaxBlack™ 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.


King Racing’s pMaxBlack™

The pMaxBlack™ overlay contains 5% copper. It is further strengthened by a proprietary nano-scaled hardening process that modifies the molecular structure and creates a black fatigue-resistant shield. The outcome is a significant 29% increase in overlay hardness (18.1HV) and overall 24% increase in load capacity (10,200 psi).

SecureBond™ – Maximum tri-metal structural integrity

High loads and high RPM’s create critical stresses that travel through the multi-layer construction of a tri-metal race bearing. SecureBond™ is a micro-etch surface preparation process that strengthens the tri-metal structural integrity. SecureBond™ reduces the likelihood of catastrophic failure due to delamination of one layer from the other under extreme load conditions or metal–to-metal contact.
