Needle and Journal Cam Follower Bearings

Needle roller and journal cam follower bearings offer several key advantages for high-performance engines. They provide increased load capacity to handle the extreme loads generated by high-pressure valve springs, reduced friction and oil temperatures for improved efficiency, and improved oil flow to the main and rod bearings. This enhanced durability makes them well-suited for maximum endurance racing applications. However, the installation of needle roller cam bearings requires additional machining work to ensure compatibility, which can add significant cost to the engine build.
