ABSTRACT:
A chain equipped with rollers and including roller joint sealing arrangements each comprising the provision of complementary sets of annular grooves in the end faces of a roller and in the inwardly facing surfaces of the sidebars of the roller chain. An annular seal member is loosely seated in each complementary set of grooves to form a labyrinth type seal to prevent lubricant efflux from the roller joint and contaminant influx into the roller joint to improve the wear characteristics of the roller joint.
