Dura-Bond High Performance Cam Bearing Set High Performance - 1967-95 SB Chevy +.010 O.D.
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-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.
Since 1947, Dura-Bond cam bearings are the industry standard against which all others are judged. Dura-Bond Bearing Company is a world leader in camshaft bearings, power metal valve seats and valve spring shim design and manufacturing. This has been recognized by over 50 years of experience as the standard of the industry, and the internationally recognized ISO-9001 and MRP-Oliver Wight Class "A" certifications.
