Durable anti-deformation bearing ring

The utility model belongs to the technical field of bearings, particularly relates to a durable anti-deformation bearing ring, and aims to solve the problems that the temperature exceeds the thermal stability limit of a material due to the fact that a large amount of heat is generated in the working process of an existing bearing, and the bearing is deformed due to additional abrasion caused by the fact that external foreign matters enter the bearing. According to the scheme, the bearing comprises a bearing outer ring, a bearing inner ring is rotationally installed in an inner cavity of the bearing outer ring, an outer roller path is formed in the inner wall of the bearing outer ring, an inner roller path is formed in the outer side of the bearing inner ring, and a plurality of balls are installed between the outer roller path and the inner roller path in a rolling mode; and a plurality of heat dissipation grooves are formed in the top and the bottom of the bearing inner ring. The bearing is reasonable in str
