Just ask any high performance engine rebuilder. It’s quality that stands the test of time. Over 2,000 hours of lab testing and a season of late model NASCAR testing proved the High Performance Bearing was up to the test. This characteristic is especially important during start-up because oil does not reach all critical components immediately. The primary advantage is that bearings with FLUOROPOLYMER Composite Coating retain engine oil on the surface, even under extreme heat and pressure conditions.īeing a lubricant itself, the coating provides secondary (back-up) lubrication in the event that momentary oil starvation occurs. This dry lubricant actually penetrates the surface where it has been applied. 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. This hard and high strength condition provides the “toughness” needed for racing applications.īurnishing: Cold working the surface of the Babbitt eliminates micro-fissures that can lead to fatigue failure. Dura-Bond Cam bearings, Performance coated cam bearings are constructed from a seamless steel tube and coated with a Fluoropolymer dry lubricant that. By leaving the structure as cast, tensile strength is almost doubled over the standard bearing. Grain-Controlled Babbit: By cooling the Babbitt quickly in the casting process, very fine grain structure is achieved.
