Tech Features
Copper Based
Tri-Metal Copper based material - Leaded or Lead Free tri layers bearings for low to heavy load engines.
pMaxBlack™
Superior load capacity - Overlay features proprietary nano-scaled hardening process producing superior load capacity.
pMaxKote™
Factory applied polymer coating - Inhouse developed Polymer coating for race applications, enhances seizure & wear resistance, with no added thickness.
U-Groove™
Greater load surface - A 90? oil groove shape, keep oil flow intact, increases bearing load capacity by expanding the surface area.
Radialock™
Optimal crush height and heat transfer - An optimal crush height value obtained from an optimization process of each performance bearing crush height
Eccentrix™
Superior hydrodynamic lubrication - An optimized eccentricity value reached through elasto-hydrodynamic analysis and dynamic calculations.
Bulls Eye™
Perfect clearance in every set - Outperforms the industry’s wall thickness tolerance, ensuring the least thickness variation shell-to-shell.
