Abstract
The utility model relates to a two-row roller bearing. The two-row roller bearing comprises an outer ring and an inner ring, wherein a plurality of rollers with central lines in a same straight line are arranged in the outer and inner rings, an annular fixing ring for preventing each roller against displacement is arranged on the outer surface of each roller, and grooves corresponding to the fixing rings are formed in the outer and inner rings. According to the two-row roller bearing, the annular fixing ring for preventing each roller against displacement is arranged on the outer surface of each roller, so that the production cost is greatly reduced.
