BMW S14B23 | S14B25 | E36 M3 | KING RACE Conrod Bearings
pMax-Black.
pMaxBlack combines a unique tri-metal structure with advanced surface processes to deliver superior load capacity.
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.
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).
