FIELD: machine building.

SUBSTANCE: invention relates to a seal of a bearing. Bearing comprises first housing (30) attached to outer race (10) of bearing, second housing (40) attached to inner race (20) of bearing and elastic sealing element. First housing (30) includes a first radially extending portion (32) extending towards the inner bearing ring (20), and second housing (40) includes a second radially extending portion (42) extending towards the outer bearing ring (10) and located in axial direction outside first radially extending part (32). In radial direction the seal has at least first (70) and second (80) chambers. First chamber (70) is formed by first (32) or second (42) radially passing part, and second chamber (80) is located in radial direction from internal side of first chamber (70). Elastic sealing element contains the first sealing component (50) entering first chamber (70), and the second sealing component (60) entering second chamber (80).

EFFECT: seal has reduced axial dimensions due to creation of multilevel seal in radial direction of bearing, which provides good sealing and simplifies installation of bearing.
