FIELD: machine building.

SUBSTANCE: invention relates to sealed rolling bearing, in particular, to four-row toper rolling bearing to support travelling and work rolls of rolling stands. Proposed rolling bearing (1) consists of axially-compound outer (2) and inner (8) races and several rolling bodies (19) rolling between races (2, 8) in for rows along roller paths (11-18). Rolling bodies (19) are held in place by appropriate cages (20-23) with identical spacing. Bearing inner space (24) between races (2) and (8), is made axially tight by sealing rings (25, 26) preventing an ingress of fluids and dirt. Every cage aforesaid cage (20-23) represents a pin-type separator consisting of the first washer (27-30), second washer (31-34) and several pins (36-39) jointed to both washers (27-34). Note that aforesaid sealing rings represent plate rings (40-43) jointed to first (27) and second (34) washers of both outer cages (20, 21).

EFFECT: sealed rolling bearings with no rpm and temperature constraints.
