ABSTRACT:
A sealed bearing assembly for a rotating shaft includes a bearing member having an integral lip which engages the shaft to form a first seal. The bearing member also has an integral collar defining a recess into which is press-fitted a separate annular member adapted to engage the shaft so as to form a second seal closely adjacent the first seal. The two seals may have different sealing characteristics. The bearing member, the lip seal, and the collar are formed integrally as a one-piece element and can be manufactured simply and cheaply from a plastics material by injection molding.
