As race engines evolve, and become more and more powerful, the need for engine bearings that can withstand the increasingly higher load capacity on these higher power engines is needed. Focusing on the Sport compact range, King is offering newly designed items for Honda engines.

pMAX Black™ – This unique tri-metal bearing structure was developed to meet the ongoing demand for increased engine bearing load capacity. The intermediate layer uses a copper based alloy with 4.5% tin for added strength that is the strongest in the industry, at 115 HV. This gives the bearing a load capacity of 17,000 psi in the intermediate! The overlay is also 24% stronger because of a 5% copper alloy with a fatigue resistance of 10,200 psi, 17% more than a standard bearing. King’s SecureBond™ etching process also improves the multi-layer adhesion and structural integrity of the bearing.

pMaxKote- Coated Bearings - King factory applied nano-composite polymer coating. King’s pMaxKote ia a revolutionary new approach to coated bearings. This unique polymer coating is applied over King’s pMaxBlack overlay at the King factory during the bearing manufacturing process. King’s pMaxKote contains ceramic nano-composite particles that function as a fourth layer to enhance wear resistance. pMaxKote does not change the bearing’s original precision wall thickness and adds no additional thickness
U-Groove™ – By using a 90° groove as opposed to a chamfered groove, the effective surface area of the bearing is increased. That in turn, increases the bearing load capacity and gives a better load distribution across the surface of the bearing.

Bull’s Eye Tolerance™ – King’s standard for bearing thickness consistency has set new standards in the industry. With King bearings, there is no need to purchase multiple sets of bearings to get the right clearance, no need to grind cranks, and no need to adjust housing diameter.

ElliptiX™ – This newly designed oil slot improves oil ingress without affecting the bearing’s surface or compromising the load capacity.

RadiaLock™ – To prevent spun bearings, King has developed a unique process to customize each bearing’s crush height to meet its specific performance demands.

EccentriX™ – By using elasto-hydrodynamic analysis, an optimized eccentricity value for each bearing is reached and the bearing is custom designed using this value to meet specific performance requirements. This process allows a more stable hydrodynamic lubrication regime is reached.
