ABSTRACT:
The rotatable joinder of two sheets is provided by a two-piece interfitting bearing assembly with each element separately attached to one of the sheets so that the sheets are joined but rotation is controlled by the interfitting bearing surfaces. The interfitting parts comprise an inner and outer race which are placed together in superposition with aligned apertures in the sheets. The rotatable attachment of the sheets is accomplished in a single pressing operation in which each race is simultaneously pressed into one of the sheets with a gap remaining between them.
