Abstract
A precision, low cost bearing for connecting the ends of two hinge links to one another for relative pivoting, the adjacent end portions of the links being formed with housings each having a socket. A spindle fixed rigidly within one of the sockets is telescoped into the other of the sockets and is formed with a taper which mates with a taper formed in the closed end portion of the latter socket. A bushing is telescoped over the spindle and into the socket and is formed with a tapered hole which mates with a second taper on the spindle. The two sets of mating tapers coact to enable the spindle to turn in the bushing with a close but free running fit in spite of diametrical and axial dimensional differences between the socket, the spindle and the bushing.
