Abstract

A self-aligning roller bearing of an asymmetric structure, comprising an outer ring (101), an inner ring (102), rolling bodies (103), a retainer (104), and a spacer ring (105) designed in a narrow floating fashion. The rolling bodies (103) are arranged in two columns and provided between the inner ring (102) and the outer ring (101); respective contact angles of the rolling bodies are different; meanwhile, corresponding inner raceway surfaces (1021, 1022) and an outer raceway surface (1011) are also of an asymmetric structure.
