ABSTRACT:
A one-piece, self-lubricating, thermoplastic bearing and sealing member suitable for supporting a moveable shaft and forming a seal around the circumference thereof. The bearing and sealing member comprises a tubular shaped body, an inner annular wall portion of which may be radially cut to form a recess and one or more flanges of preselected length and thickness. Alternately the sealing and bearing member may be molded with the flange and recess formed in situ. The flanges may have an inner diameter which is smaller than the outer diameter of the shaft or may have an outer diameter which is larger than the outer diameter of the bearing and sealing member. The flanges can be bent, preferably in the vicinity of their respective bases to a preselected angle below 20.degree. relative to a transverse axis of the sealing member. When a moveable shaft is disposed in an annular conduit with the bearing and sealing member, the flange portions of the bearing and sealing member within the conduit are bent to said preselected angle and are placed in contact with the annular outer surface of the shaft, providing sealing engagements therebetween.
