Abstract
An idler roller assembly is comprised of a polymeric tubular body and an end cap fitted within a cavity of the tubular body at each end of the tubular body. An inner circumferential surface of the tubular body defining the cavity is configured with a plurality of recesses to define first, second and third cavity portions, with the third cavity portion being adjacent to each end of the tubular body. The first and third cavity portions have an inner diameter that is greater than an inner diameter of the cavity, and the second cavity portion has an inner diameter greater than the inner diameter of the first and third cavity portions. An end cap configured to house a bearing race to support each end of the tubular body on a shaft is configured with a first end, a second end and an outer cylindrical wall therebetween. The outer cylindrical wall is stepped to provide first, second and third outer cylindrical surface portions sized to fit closely within the first, second and third cavity portions of the tubular body. The outer cylindrical wall is radially tapered between the first and second outer cylindrical surface portions to facilitate insertion of the end cap within the cavity of the tubular body.
