Abstract

A tension or idler roller for a belt drive system has an outer roller for engaging a belt, an inner support body adapted to be affixed to a machine, and a rolling bearing between the outer roller and the support body. The support body is comprised of a pair of identical cup-shaped elements oriented either with their open ends toward one another or their closed ends toward one another, the shells having an eccentric mounting. The inner ring of the bearing may be a separate element or it may be formed in the shells.
