Sandvik 152 522 88 Bushing

The bushing, part 152 522 88, is one of a line of sleeves that support the same shaft or pin at more than one point, and in that arrangement the bores have to be aligned with each other as well as correctly sized. If one bushing in the line is much more worn than its neighbour, the shaft sits at a slight angle, load is carried on the edge of the sleeve instead of along its length, and the ends of the bushing wear first.

A bushing showing a bright wear band at one edge only, rather than evenly around and along the bore, is evidence of misalignment more than of simple age. In that case the neighbouring sleeves and the housing should be checked at the same time, because replacing a single bushing in a worn line gives only a short improvement before the load moves again. Fitting it to the right reference keeps the length and bore proportions that the line of bushings was laid out around.
