Claims4
In a bowed roll of the type having an elongated shaft;
- a plurality of spools disposed about said shaft for rotation;
- and a plurality of ball bearings disposed along said shaft, each of said bearings having an inner race in contact with said shaft, an outer race in contact with one of said spools and a pair of side walls extending between said races and cooperating with said races in defining a ball chamber said side walls being affixed to one of said races and slidable with respect to the other of said races;
- the improvement comprising a lubrication system for providing lubricant to the interior of said ball chamber including a lubricant reservoir, a lubrication fitting extending into said chamber through one of said sidewalls of each of said bearings and a lubricant line extending between said reservoir and said fitting along said shaft whereby lubricant may be injected directly into said chamber.
