ABSTRACT:
A self-lubricating track-roller bearing and the method of manufacturing the same that includes such a bearing with an inner race ring having a liner of self-lubricating material bonded to the outer surface of the inner race ring which is manufactured by the use of such a liner having self-lubricating material on one side and adhesive on the other side, with the latter side applied to such inner ring outer surface, positioning such inner ring with the liner thereon and a transparent heat shrinkable tubing assembly fixture together in a concentric relation so that upon the application of heat to said fixture it shrinks into a circumferential contact with the said liner to exert a force as the shrinking occurs to press said liner and said adhesive thereon against said outer surface to bond the latter thereto and thereby compress the thickness of said self-lubricating material, with said heat-shrunken tubing fixture maintaining said liner in position during additional heating to cure said adhesive, then removing said tubing fixture from said inner ring by cutting the same in an axial direction and then disposing of the cut fixture, and thereafter assembling said inner race ring with said liner thereon within an outer race ring to provide a self-lubricating track-roller bearing for an installation wherein said outer ring is rotatable and said inner ring is stationary relative to said outer ring.
