The double sealing rings are arranged to provide a labyrinth seal to aid in the retention of lubricant within and the exclusion of contaminants from the assembly, and the inner ring of each pair also provides an axial thrust bearing surface for the roller. The sealing rings are preferably of L-shaped cross section and are adaptable for use with rollers of either metal or platic construction.
