Abstract: The present invention relates to device and method for manufacturing a wheel bearing assembly that reduces an error rate by reducing stress concentrated on rolling elements in manufacturing processes of the wheel bearing assembly. The device for manufacturing a wheel bearing assembly may include: a base, on which a hub is mounted, supporting the hub in a case of orbital-forming; a forming tool mounting portion mounted above the base; a rotating portion rotatably connected to an outer ring and rotating or pivoting the outer ring about a hub axis in a case of the orbital-forming; and a forming tool mounted at the forming tool mounting portion, rotating on a first axis slanted to the hub axis by a predetermined angle, and simultaneously orbiting about a second axis parallel with the hub axis.

Abstract: A package bearing includes two cones that fit over a spindle on a wheel hub, a double cup that surrounds the cones and is configured to bolt against the suspension system of a vehicle, and tapered rollers that are located between opposed raceways on the cup and the two cones. The cup at each of its ends has an end bore. The end bore at the outboard end contains a seal which establishes a dynamic fluid barrier with the outboard cone. The end bore at the inboard end contains a flexible retainer that creates a closure between the cup and the inboard cone. The end bore at the outboard end also receives an end cap which extends across the end of the inboard cup and the end of the spindle to close the entire inboard end of the bearing. The seal and retainer unitize the bearing for shipping and handling. The retainer further keeps grease from migrating into the end cap during the operation of the bearing.
