Patent abstract
The present invention relates in general to roller assembly apparatuses, and specifically to roller assembly apparatuses used in treadmills. An embodiment of the invention includes a roller apparatus, comprising: a shaft with raised surfaces on each end, a rotatable tube disposed around a portion of the shaft, and bearing assemblies. The bearing assemblies are disposed between the raised surfaces of the shaft and the rotatable tube such that the inner surfaces of the bearing assemblies contact the raised surfaces which allows the inner surfaces of the bearing assemblies to rotate on the raised surfaces, thus eliminating forces on the inner surfaces of the bearing assemblies.
