ABSTRACT:
A low friction bushing is made by winding a continuous strand of bondable low friction thread impregnated with a bonding resin into the shape of a hollow cylinder having an axial length greater than the finished bushing. The cylinder is inserted into an annular cavity and with heat and pressure is axially compressed therewithin to radially expand it and compact the thread turns and fuse the resin into a solidified matrix with the thread and resin matrix completely filling the cavity and thereafter the solidified bushing is removed from the cavity. One of the cylindrical walls of the cavity is finished with a surface of bearing quality such that the surface of the bushing pressed thereagainst will be of a complementary quality.
