Abstract: A system and method for the manufacture of aircraft landing gear axle equipment is provided of two primary steps: hot pierce and tube solid billet stock; and flow form process. The hot pierce and tube process converts a standard solid round billet by heating it well beyond its annealing temperature. The billet is then pierced with a lance and hot rolled into a seamless tube. The tube is then precision flow formed as an incremental metal forming technique in which a tube of metal is formed over a mandrel by a multiple rollers using tremendous pressure. The rollers deform the work piece, forcing it against the mandrel, simultaneously lengthening the part axially and radially thinning the cross-sectional wall of the workpiece.

Abstract: A boat trailer roller wheel mounting system for carrying an insignia in a predetermined orientation is provided. Included is a closed-ended wheel bushing which carries indexing for mating with an indexed wheel support arm in a predetermined, rotational orientation. The roller wheel turns on and is held by the indexed bushing. A quick release retainer ring fixes the bushing to the support arm and acts as an inboard longitudinal movement stop for the wheel. The bushing indexing on the support arm transfers the rotational thrust created on bushing, due to the rotation of the wheel under a load, directly to the support arm and therefore eliminates this rotational thrust from acting upon the retainer ring. An end cap is formed at the closed outer end of the bushing and has an annular projection surface extending beyond the bushing surface to provide a longitudinal thrust surface against which the wheel hub can operate.
