Abstract
The utility model discloses a deep groove ball bearing provided with a pulley groove at the external diameter of an outer ring, comprising an outer ring, an inner ring, a retainer cover, a retainer base, a steel ball and a rivet, wherein a crescent-type pulley groove is arranged at the external diameter of the outer ring, and the pulley bearing only needs finish tuning without needing grinding, so that the cost is lowered; and the frictional force is increased when the pulley bearing is used, so that the problem of relative slip is solved. The utility model discloses a pulley bearing which is suitable for being used by a pulley, and has the characteristics of being convenient in installation, and flexible in use.
Description
