Features
Multiple-layer construction provides numerous benefits, such as a blend of characteristics to provide high strength and excellent seizure resistance
No flash plating is applied to further improve bearing retention and maximize heat transfer
Improved bearing retention from higher radial contact pressure which locks the bearing into the housing
ACL Race Series performance engine bearings feature increased eccentricity to increase improve shape adaptation to compensate for bore distortion at high speed operation
Full 180° grooved uppers with matching partial groove in lowers. This reduces interruption to big end oil supply
Tapered groove run-out which smooths big end supply cut-off avoiding pressure pulsing and cavitation
