The surface also exhibits a higher hardness. Cold working the surface of the Babbitt eliminates micro-fissures that can lead to fatigue failure. This hard and high strength condition provides the "toughness" needed for racing applications. This item: Dura-Bond CH-10 Camshaft Bearing Set for Chevy LS1 25.08 King Rod and Main Bearing set for LS engines including 4.8L, 5.3L, 6.0L V8 68.86 Melling M295 Oil Pump, Wet Sump, Internal, Standard Volume, GM LS-Series, Each 61.99 Dura-Bond CH-23 Cam Bearing Set 32 3 offers from 34. By leaving the structure as cast, tensile strength is almost doubled over the standard bearing. By cooling the Babbitt quickly in the casting process, very fine grain structure is achieved. These cam bearings are babbitt on steel, and are precision machined and then micro-finished to offer. 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. 635 Wide OEM Replacement CS5503BB King Engine BB-Series cam bearings are recommended for OE rebuild applications. For many years, nearly all camshaft bearings were manufactured with a lining.
Race Series rod and main bearings are standard components in race engines that have set records and won championships from Mexico to Bonneville - from sport compact drift racing to small block NASCAR, IHRA and NHRA cmpetitions. Tips for maximizing cam bearing performance in high performance and stock engines. They may look alike to the naked eye, but they’re sized to fit into the cam hous. 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. ACL Race Series performance engine bearings are recognized as a premier brand throughout the motorsports world.
