Abstract
A bushing comprising a main body that is adapted to be supported by the first member. The main body is comprised of a rigid layer and one or more other layers supported by the rigid layer. One of the layers defines an axial bore that is adapted to receive a pin that movably couples the second member to the first member.
Claims4
A bushing adapted for movably coupling a first member to a second member, said bushing comprising:
- a main body that is adapted to be supported by the first member, said main body is comprised of an inner layer, and an outer layer, and a rigid layer located between said inner and outer layers, said inner layer defining an axial bore that is adapted to receive a pin that movably couples the second member to the first member, said outer layer being adapted to be inserted into the first member, wherein said inner and outer layers are formed of a pliable, chemically lubricated plastic.
A bushing adapted for movably coupling a first member to a second member, said bushing comprising:
- a main body that is adapted to be supported by the first member, said main body is comprised of an inner layer, and an outer layer, and a rigid layer located between said inner and outer layers, said inner layer defining an axial bore that is adapted to receive a pin that movably couples the second member to the first member, said outer layer being adapted to be inserted into the first member, wherein an outer surface of said outer layer is provided with a protrusion that is dimensioned to produce a tight, press fit relationship between said main body and the first member.
