Leads The Way in Technology
As a technological leader and OEM development partner, King is committed to being at the leading edge of bearing technology to meet our customers’ needs all over the world.

To maintain our position as the leading developer of engine bearings, King established our TechLab. This research and development unit is constantly monitoring market changes to transform the future of bearings by formulating new bearing designs and materials. King’s R&D department utilizes advanced ENSIM™ software to analyze and simulate variable bearing conditions using a wide range of equipment. This system allows us to create and test all new bearing designs and determine the optimal configuration for that application. King is also able to analyze engines after real-world use to improve bearing designs. We then leverage this information by applying the data to our aftermarket bearing designs.

The King TechLab’s Latest Innovations:

pMAX Black™- Metal Structure: A unique tri-metal structure for race engines, the 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 result is a significant 24% increase in hardness and load capacity, reaching 18.1HV and maximum fatigue resistance of 10,200 psi.


Silver based sputter replacement: A lead free silver based overlay material containing solid lubricant additives distributed throughout the silver matrix. For extreme load engines. To read more about King lead-free materials

King’s TechLab has developed unique geometric features such as:

ElliptiX™-  a newly designed oil slot/oil hole hybrid that improves oil ingress

U-Groove™-  a 90 degree oil groove shape to increases bearing load capacity by expanding the surface area and more.
