Performance Cam Bearing Set

Traditional bearing construction is based upon a three layer configuration composed of a steel backing, a copper-lead layer and a very thin overlay of babbitt material only 0.0005" - 0.0008" thick. JEGS Cam Bearings use just two layers, a high strength steel backing plus a bonded layer of aluminum silicon material 0.015" thick. Aluminum silicon material is an alloy of tin, silicon and copper in an aluminum matrix. Because it is an alloy, it maintains its properties throughout its entire depth, delivering consistent and reliable performance. Both JEGS Performance and High Performance Cam Bearings are made from the same material. The High Performance Cam Bearings are micro-fine machined and have chamfered oil holes. Features and Benefits: Particle Embedability More than half of engine bearing failures are caused by metallic particles which scratch crank journals and tear or weaken thin babbitt overlays such as in the tri-metal bearing. Since JEGS aluminum silicon bearing layer is much thicker than the babbitt overlay (0.015" vs. 0.0008"), it provides eighteen (18) times more embedability than a tri-metal bearing to catch and hold particles so they don't scratch the bearing journals. This is especially true for particles over 0.0004" in diameter which cause most of the damage. Conformability The much thicker layer of aluminum silicon bearing material (0.015" vs. 0.0008") allows the bearing to conform to problems such as metal to metal contact when there is mis-alignment present. Greater conformability means fewer bearing failures. Temperature Resistance The aluminum silicon material's melting/fatigue point is over 450degree F, 100degree more than that of the thin babbitt overlay in a tri-metal bearing (400degree F). This means added protection against localized overheating due to mis-alignment, detonation, overloading, loss of coolant, etc. High Load Capacity Alecular bearings
