Abstract:
A method of assembling an idler roll having an outer shell and end bearing assemblies comprising the steps of:a) providing a hollow cylindrical outer shell and a pair of end bearing assemblies, said end bearing assemblies each comprising a bearing having an inner and outer race, with said outer race affixed to an end cap and an inner race adapted to be press fit on an end of a roller shaft; b) providing a roller shaft having an outside diameter slightly larger than an inside diameter of said inner race; c) press fitting the inner race of each bearing assembly on said shaft at opposite ends thereof to an initial position which is spaced axially outwardly from a final desired position; d) fitting each end cap within the ends of the outer shell; e) welding each end cap to said outer shell; f) restraining said outer shell and reciprocating said shaft along its longitudinal axis and relative to said shell to determine the degree of axial movement and, therefore, bearing clearance; g) moving said inner race of said bearing assembly from its initial position to its final position as determined by said degree of axial movement.
