Abstract
A system continuously lubricates critical areas, such as bushings and seals, in a cam brake shaft. A fresh source of lubrication is provided at a generally constant pressure. This is accomplished using a centrally located spring and an adjacent pair of axially sliding inboard seals that apply a continuous pressure to strategically disposed lubricating fluid between each of a pair of main seals at each end of the tubular cam housing and a respective inboard seal positioned at an end of the centrally located spring.
