The utility model provides a manufacturing device of a wheel bearing and aims at solving problems that by means of existing track forming methods, diameters of inner wheels are expanded towards outer wheels during processing of tail end portions of hubs. The manufacturing device of the wheel bearing comprises a wheel bearing which comprises a hub, an inner wheel, an outer wheel, rotation members, a base, a forming tool installation portion, a forming tool and a forming guiding tool. One end of the hub is combined with a wheel of a vehicle, and the other end of the hub is provide with a segment difference portion and a tail end portion; the inner wheel is connected with the segment difference portion of the hub; the outer wheel is connected with a vehicle body; the rotation members perform track forming on the tail end portion of the hub towards the direction of the outer side of the radius of the inner wheel; the base is used for installing the hub and supporting the hub during track forming; the forming tool installation portion is installed on the base; the forming tool is installed on the forming tool installation portion; and the forming guiding tool is inserted between the inner wheel and the outer wheel before track forming, supports the inner wheel and is arranged on the upper portion of the base in a lifting mode. By means of the manufacturing device of the wheel bearing, diameters of the inner wheel can be prevented from expanding towards the outer wheel, and rejection rates of wheel bearings are reduced.
