ABSTRACT:
A bushing is provided which is arranged to be press fit into a bushing bore. The bushing is adapted to support a high level load which is unidirectional or which changes in direction through only a small angle. A rigid core in the bushing has a long rubber, or rubber-like, semicylinder bonded to one side of the outer surface thereof and has a number of uniformly spaced short rubber semicylinders bonded to the other side thereof. The short semicylinders have a greater wall thickness than the long semicylinder so that when the bushing is pressed into the bushing bore the space between the core and the wall of the bore is practically filled on the short semicylinder side. The long semicylinder operates in compression to support the high level load without exceeding the rubber endurance limits and therefore avoids the effects of internal deterioration in the rubber.
