Patent ID: 7654745

Claim:
A bearing assembly for rotatably joining two sheets, comprising: a planar top sheet having a first aperture; an outer race located within said first aperture and having an axial bore and means receiving a cold flow of metal from the top sheet rigidly attaching it thereto; a bottom sheet in face-to-face relation with said top sheet and having a second aperture in axial alignment with said first aperture about an axis; a unitary inner race partly located within said axial bore of said outer race and extending axially at least to a point partially within said second aperture, said inner race having circumferential clinch attachment means receiving a cold flow of metal from said bottom sheet rigidly securing it to said bottom sheet; and wherein said inner race has a head of increased diameter greater than the diameter of said outer race bore thereby captivating the top sheet to the bottom sheet, said inner race and outer race being closely dimensioned to rotatably join the top sheet to said bottom sheet about said axis.
