Double-row radially self-aligning roller bearing

摘要

The disclosure concerns a double-row, radially self-aligning, roller bearing. The bearing has an outer race ring and an inner race ring. Two annular arrays of rollers are carried in respective cages located at the two axial sides of the bearing. Each cage defines a respective pocket for each roller of the roller bearing. The circumferential side walls of a pocket are generally profiled to the sides of the respective roller. The cages are also defined by an axially inward and axially outward ring which joins the pocket walls. The diameters and placements of the rings of the cages are selected so that in an axial projection of the rings, one upon the other, the rings do not intersect. The axially more inward ring has an inner diameter that is not less than the outer diameter of the axially more outward cage ring, and the bearing rollers are inclined appropriately. The cages are comprised of elastic, flexible, plastic material enabling the cages thus shaped still to be installed in the race rings.
