The utility model further provides that: the outer peripheral wall of the sealing ring is in threaded fit with the inner peripheral wall of the corresponding connecting ring.

The technical scheme is beneficial in that: screw thread cooperation sets up between seal ring periphery wall and the interior periphery wall of corresponding connecting ring, and then makes things convenient for operating personnel's dismouting, improves bearing packaging efficiency.

The utility model further provides that: the outer peripheral wall of the matching ring is provided with a baffle ring in a protruding mode, and the outer side wall of the baffle ring is in clearance fit with the inner side wall of the sealing ring.

The technical scheme is beneficial in that: the arrangement of the baffle ring in the technology improves the sealing performance between the sealing ring and the matching ring, and further reduces the possibility that external impurities invade the bearing.

The utility model further provides that: the baffle is arranged on the inner peripheral wall of the connecting ring in a protruding mode, and the outer side wall of the baffle is attached to the inner side wall of the sealing ring.

The technical scheme is beneficial in that: the arrangement of the baffle can avoid the excessive spiral of the closed ring on the connecting ring, so that the closed ring is placed into the rolling cavity to influence the operation of the bearing.

The utility model further provides that: and two ends of the outer peripheral wall of the inner ring are connected with limiting rings in a threaded manner, the two limiting rings are arranged outside the respective adjacent closed rings, and the two limiting rings are arranged in clearance fit with the respective adjacent closed rings.

The technical scheme is beneficial in that: after the sealing ring is installed, an operator is connected with the limiting ring on the inner ring in a threaded mode, and the limiting ring is located on the outer side of the sealing ring, so that the sealing failure of the bearing caused by the fact that the sealing plate is separated from the bearing is prevented.
