Successful race engine builders are constantly pushing the limits of load capacity to new levels. Race bearings today inevitably need to match these demands with more competitive bearings. At King Racing we met the challenge with the XP high performance bearings series.
The XP series is a line of bearings with advanced metallurgical and geometric technologies that meet extreme performance loads. It was developed for all performance applications that use forged steel aftermarket crankshafts and produce high loads for extended periods.
King Racing’s XP series features pMax Black™, a unique tri-metal structure that is 24% harder than any other conventional tri-metal race bearing. pMax Black™ together with the XP geometric features are the ideal combination for performance racing. For more on King Racing technologies visit TechLab
- 24% greater load capacity
- 17% more fatigue resistance
- Compatible with all crankshafts
- pMax-Black™ combines a unique tri-metal structure with advanced surface processes to deliver superior load capacity.
pMax-Black™ tri-metal structure
Intermediate layer
The intermediate layer of a typical race bearing contains 2-3% tin, with hardness values of 90-95 HV. Within the pMax Black™ intermediate layer, we increased the tin content to 4.5%, making it 22% harder at 115 HV, with a load carrying capacity of 17000 psi.
pMax-Black™ Overlay
The overlay of a typical high performance bearing features a leaded alloy that contains 2-3% copper content. The bearing ‘reaches a hardness level of 11-11.5 HV, and a maximum fatigue resistance at 8000-8500 psi.
King’s pMax Black™ overlay is significantly stronger than conventional overlays due to its 5% copper content and an innovative nano-scaled hardening process.
King Racing pMax Black™ overlay is 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 24% increase in hardness and load capacity, reaching 18.1HV and maximum fatigue resistance of 10,200 psi.
SecureBond™ – Maximum tri-metal structural integrity
High loads and high RPM’s create critical stress levels that filter through the multi-layer construction of a tri-metal race bearing. SecureBond™ is a micro-etch surface preparation process. It strengthens the tri-metal structural integrity, reduces likelihood of catastrophic failure due to delamination of one layer from the other under extreme load conditions or metal–to-metal contact.
