ABSTRACT:
A "centerless" swivel bearing for chairs and the like in which the two facing, relatively rotatable members are each in sliding contact with an interposed lubricating liner on a ring of substantial diameter defining a central opening in the bearing. One of the two members is necked through the opening of the other and then turned radially outwardly to maintain the assembly of the three constituent parts against loading tending to separate the two members.
