Abstract
A self-lubricating track roller and a method of making the self-lubricating track roller are disclosed. First, an inner ring is provided having a radially outwardly facing surface. A parting agent is applied onto the radially outwardly facing surface. Next, a self-lubricating material is applied over the radially outwardly facing surface. Then, an outer ring is formed around the self-lubricating material such that a radially inwardly facing surface of the outer ring is bonded to the self-lubricating material. A resilient tire is bonded onto the radially outwardly facing surface of the outer ring. In the resulting track roller, the radially outwardly facing surface of the inner ring has a surface profile that corresponds to a mating surface profile of the self-lubricating material that is bonded to the radially inwardly facing surface of the outer ring.
