Abstract
This bush is made out of a composite material that has a modulus of elasticity of between 500 and 6000 N/mm2, said bush having at least one lip formed directly at the time of manufacture as an overrun edge of its bore to act as a leak-tight or protective barrier after mounting on the shaft by creating a tightening effect between the inside diameter of said lip or said lips, and the outside diameter of said shaft.
