Abstract
Abstract A tension roller for belt drives comprises a pin designed as a hollow member and a roller member supported on the pin by way of a rolling bearing, with an inner ring, rolling means and an outer ring supporting the roller member. The pin is formed by two thin-walled sleeves positioned at opposite ends of the bore of the inner ring and the rolling bearing. At least one of the sleeves is provided on the surface thereof with a radial shoulder for emplacement of the inner ring.
