The invention relates to a sealing wheel with a bearing friction-free line hanging pin and belongs to the field of fishing gear. The sealing wheel comprises a shell and is characterized in that a wheel seat is mounted in the shell, a spool for winding a fishing line is mounted on the wheel seat, a spindle slidably penetrates the center of the wheel seat, a rotator is connected to one end of the spindle, a line outlet seat is arranged on the end face of the inner side of the rotor, the line hanging pin is connected to the line outlet seat, an elastic part for driving the line hanging pin to retract into the rotor is arranged between the line outlet seat and the rotor, and a cam component is arranged at the end of the wheel seat; the cam component comprises a bearing and a gland, the bearingis mounted at the end of the wheel seat through the gland in a press fitting manner, one end of the gland is connected with the wheel seat in a threaded manner, and the other end of the gland is provided with a cam arranged on the bearing in a press fitting manner. The sealing wheel has the advantages that the bearing is used to replace a cylindrical part in the prior art to push the line hangingpin to extend out of the rotor, direct-contact slide friction between the bearing and the line outlet seat is changed into rolling friction between the inner ring and the outer ring of the bearing, and the abrasion problem of slide friction is solved effectively.
