Oriented roller bushing for boat trailer

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. The positive orientation of the bushing to the support arm establishes a predetermined orientation of the end cap. This permits an insignia placed on the outside face of the end cap to always have a predetermined orientation, when the mounting system is assembled.
