Precision Machining: High Performance manufacturing tolerances are closer to control installed oil clearances, which reduce operating bearing pressure.The surface also exhibits a higher hardness.

By leaving the structure as cast, tensile strength is almost doubled over the standard bearing. Dura-bond Cam Bearings, High Performance, Bi Metal, Chill-Cast Micro Babbit, Coated, Chevy, LS1, Set. Cam Bearings, High Performance, Bi Metal, Chill-Cast Micro Babbitt, Coated, Chevy, LS1, Set.

Grain-Controlled Babbit: By cooling the Babbitt quickly in the casting process, very fine grain structure is achieved.

Micro-babbitt: A very thin layer of lining which reduces the microscopic deflections that occur to a bearing when loaded and thus increases fatigue life.

Specific Contributions of the Design and Processes: The high performance cam bearings offer more than double the fatigue strength of conventional bearings, withstand racing spring loads, and maintain the excellent surface characteristics of Babbitt.
