The invention discloses a bearing lock and relates to the field of locks. The bearing lock is technically characterized in that the bearing lock comprises a door lock panel, a bearing installed on the door lock panel, and a lever handle rotating shaft inserted in a bearing inner hole, and the bearing is connected with the door lock panel through a connecting structure arranged on the bearing; the outer edge, away from the door lock panel, of the bearing inner hole extends along the inner circle of the bearing to form a concave edge, and the concave edge is abutted against the outer ring of the bearing. Due to the arrangement of the connecting structure and the concave edge, the bearing clamped to the bearing inner hole is always located in the bearing inner hole, and the bearing is prevented from sliding out of the bearing inner hole in the use process. Compared with the Chinese utility model file which is mentioned in the background technology and has the application number of 2008201752246, the bearing lock is advantageous in that the service life of the bearing or the service life of the bearing lock is remarkably prolonged in the use process due to the fact that screw holes and set screws are omitted.
