Self-aligning track roller

摘要

A track-roller bearing assembly is disclosed which includes a fixed inner ball race member having an outwardly facing arcuate peripheral bearing surface; an annular body of self-lubricating bearing material affixed to the outwardly bearing surface of said inner race; and a coaxial outer race which is rotatable about an axis of the inner race and anguarly displaceable relative to the axis of the inner race so as to accommodate track deflections or irregularities. The track-roller further includes a resilient element disposed between respective ends of the inner and outer races so as to bias the races back into axial alignment after they have been angularly displaced relative to each other.
