<p>The present invention provides a self-lubricating track roller (10) and a method of making the self-lubricating track roller. First, an inner ring (12) is provided having a radially outwardly facing surface (14). A parting agent is applied onto the radially outwardly facing surface (14). Next, a self-lubricating material (15) is applied over the radially outwardly facing surface (14). Then, an outer ring (16) is formed around the self-lubricating material (15) such that a radially inwardly facing surface (18) of the outer ring (16) is bonded to the self-lubricating material (15). A resilient tire (22) is bonded onto the radially outwardly facing surface (20) of the outer ring (16). In the resulting track roller, the radially outwardly facing surface (14) of the inner ring (12) has a surface profile that corresponds to a mating surface profile of the the self-lubricating material (15) that is bonded to the radially inwardly facing surface (18) of the outer ring (16).</p> |
