The present disclosure is directed to a bearing for a wind turbine. The bearing includes an outer race, an inner race, and a radially-split center race configured between the inner race and the outer race. Further, the center race includes a first race portion and a separate second race portion. In addition, the first and second race portions are arranged together in an axial direction. The bearing also includes a first set of rolling elements positioned between the inner race and the center race and a second set of rolling elements positioned between the center race and the outer race. L'invention concerne un palier pour une éolienne. Le palier comprend une bague de roulement externe, une bague de roulement interne et une bague de roulement centrale fendu radialement configuré entre la bague de roulement interne et la bague de roulement externe. En outre, la bague centrale comprend une première partie de bague et une seconde partie de bague séparée. De plus, les première et seconde parties de bague de roulement sont agencées ensemble dans une direction axiale. Le palier comprend également un premier ensemble d'éléments de roulement positionnés entre la bague de roulement interne et la bague de roulement centrale et un second ensemble d'éléments de roulement positionnés entre la bague de roulement centrale et la bague de roulement externe.
