Abstract
Disclosed is a double row tapered roller bearing assembly employing a contoured, maximum journal-contact bearing seal wear ring especially adapted to be installed on a journal at the end of a shaft or axle with the wear ring providing an interference fit contact area engaging the journal over at least a major portion of the axial length of the wear ring. Stress risers are eliminated by providing smooth contoured surface junctures to thereby substantially reduce fretting wear on the journal, with the increased contact area facilitating heat transfer to the shaft to extend seal life.
