A track roller includes a roller shell, a roller shaft extending through the roller shell, and a collar. The collar includes a center body interference-fitted upon the roller shaft, and a seal carrier. A clearance extends radially between a center body outer surface and a face seal assembly held in axial compression between the seal carrier and the roller shell. An oil void is formed in the center body and fluidly connected to the clearance to provide an increased oil volume for lubrication and heat-dissipation.
