ABSTRACT:
A single piece, elongate sleeve bearing or bushing device is suitable for use in a bushing hole of a wide free spinning member, such as in the deep bushing hole of a long idler roller, a wide idler pulley, a wide idler gear or the like, to form at least a pair of axially spaced bearing surface regions about a shaft. The single piece bushing device has a thin generally cylindrical wall, an oversized central bore, and a plurality of axially spaced, oversized exterior surface regions including one located at each end of the thin wall. The raised regions are interspaced by a low region, and are compressed locally upon assembly in order to press fit the bushing device into the deep bushing hole of the free spinning member. Such compression causes radially aligned regions of the interior surface of the central bore to close in on the shaft, thereby forming a plurality of axially spaced and pre-aligned bearing surface regions about the shaft.
