HIGH-PERFORMANCE CAM BEARINGS
The high-performance all-round cam bearings offer more than double the fatigue strength of conventional bearings, withstand racing spring loads, and maintain the excellent surface characteristics of Babbitt.

Specific Contributions of the Design and Processes:
Micro-Dura-bond High-Performance Babbitt: A very thin layer of lining which reduces the microscopic deflections that occur to a bearing when loaded and thus increases fatigue life.
Grain-Controlled Babbit: By cooling the Babbitt quickly in the casting process, very fine grain structure is achieved. By leaving the structure as cast, tensile strength is almost doubled over the standard bearing. This hard and high strength condition provides the “toughness” needed for racing applications.
Burnishing: Cold working the surface of the Babbitt eliminates micro-fissures that can lead to fatigue failure. The surface also exhibits a higher hardness.
Precision Machining: High-Performance manufacturing tolerances are closer to control installed oil clearances, which reduce operating bearing pressure.
