FIELD: mechanical engineering; conveyors.
SUBSTANCE: invention relates to equipment of sintering and roasting machines, namely, to conveyor trolleys and design of their bearing units. Proposed bearing unit contains axle, running roller body and roller bearings mounted in between. Outer and inner races of bearings are fixed on axle by cover and thrust washer, respectively. Radial ball bearing is slacklessly fitted on axle between roller bearings. Fitting of outer race of radial ball bearing in bore of body of running roller with clearance over diameter relieves the bearing from radial forces making it possible to take up effectively only axial forces.
EFFECT: increased service life of bearing unit.
