ABSTRACT:
A bearing and seal assembly for rotatably supporting an open front end of a clothes dryer drum includes a ring of felt-like material positioned between the circular open front end of the drum and a circular support flange of smaller diameter coaxially nested within the end of the drum. The felt-like material is fixed to the flange and substantially fills an annular space between the drum and the flange to preclude air leakage therebetween. The upper or outer surface of the felt seal, which is in engagement with the circular open front end of the drum, is powder coated with a wear-resistant material such as polytetrafluoroethylene. The powder-coated surface is slidably engaged by the drum and bears the weight of the end of the drum. The felt-like material acts as a sound dampener and shock absorber between the rotating drum and the fixed flange to preclude transmission or generation of undesirable noise caused by rotation of the drum.
