Rotor bearing for a wind turbine (100) with an inner ring (2) and an outer ring (3), which are rotatable relative to one another and delimit a bearing inner space (4) in which at least one row of rolling elements (5) which can roll between the bearing rings is arranged, and with an outlet (6) for discharging lubricating oil emerging from the bearing inner space (4), wherein the bearing inner space (4) is open towards the outlet (6) so that lubricating oil can be discharged at atmospheric pressure from the bearing inner space (4) via the outlet (6) and the outer ring (3) is designed as a nose ring (9), on which at least two raceways (10) are formed for rows of rolling elements (5) which can roll between the bearing rings (2, 3) and to which a respective oil collecting ring (11) is connected in a rotationally fixed manner on both sides, which oil collecting rings (11) extend inwards in the radial direction (R) beyond the radially outer edges (12) of the raceways (10) to each form an oil sump (8), characterized in that the two oil sumps (8) are connected to one another via at least one channel (13) passing through the outer ring (3).
