What are the advantages of Upgraded Thrust Parts?
When used in extreme high performance applications, the original bronze material used in the standard thrust bearing cannot carry the increased axial load. The increased center point load over the unsupported thrust face can cause the material to flex. In extreme conditions, this flexing can create contact between the thrust faces resulting in immediate failure. The material used in the Performance Thrust System is a special steel alloy. The steel has a higher stress limit than bronze and is also a more rigid material, which will deflect less under the same loads. The material used for the thrust bearing is a special alloy designed for use in applications requiring high strength and good bearing properties. It has up to 10% porosity making it an ideal bearing surface by absorbing the oil like a sponge. To enable the thrust system to carry the increased load, the thrust collar and spacer are manufactured to a larger diameter. This spreads the load over a larger area. An extra oil feed supply hole to the center of the bearing helps to increase lubrication to the larger thrust face and also improves cooling.
