ABSTRACT:
A centralizing bushing associated with a shaft for reducing noise and fluctuations between the bushing and the shaft when they are moving relative to each other. The bushing is mounted in the rider and includes a bearing engagable with the shaft. There are high friction, elastomeric means engagable with the bearing for limiting movement of the bearing away from the shaft and the rider is under unbalanced radial load conditions. The coefficient of thermal expansion of the bearing is essentially the same as the coefficient of thermal expansion of the shaft. The bearing is made of a thermoplastic resin mixed with carbon fiber and having a coefficient of thermal expansion which is essentially the same as that of the shaft such that the shaft and bearing will expand and contract essentially at the same rate in response to the temperature changes.
