Integrated bearing assemblies for guided attack rockets

摘要

A guide mechanism, configured for use with a guided attack rocket, includes an inner housing partially disposed in an outer housing. The inner and outer housings each define a forward end and an aft end. A first angular contact bearing is positioned between the outer housing forward end and the inner housing forward end. A second angular contact bearing is positioned between the outer housing aft end and the inner housing aft end. A retaining nut is received over the inner housing forward end. The retaining nut preloads the first and second angular contact bearings. Each of the angular contact bearings includes an inner member disposed within an outer member. The outer member defines an outer raceway and the inner member defines an inner raceway. A plurality of rolling elements is disposed between the outer raceway and the inner raceway.
