    摘要： A bearing assembly is disclosed herein. The bearing assembly includes a first inner ring and a second inner ring, as well as an outer ring. A first plurality of rolling elements are arranged to be supported between the first inner ring and the outer ring. A second plurality of rolling elements are arranged to be supported between the second inner ring and the outer ring. A third plurality of rolling elements are arranged to be supported between the second inner ring and the outer ring. The second plurality of rolling elements is arranged axially between the first and third plurality of rolling elements. Various dimensions and aspects of the bearing assembly are designed in order to provide increased efficiency and a reduced envelope.

    摘要： A rotary shaft locking device includes a rotary shaft, a first angular contact ball bearing, a support, and an actuator. The rotary shaft is rotatable about a first axis and has a first contact surface. The first angular contact ball bearing includes an inner ring connected to the rotary shaft, an outer ring, and a plurality of balls disposed between the inner ring and the outer ring. The support has a second contact surface and rotatably supports the rotary shaft via the first angular contact ball bearing. The actuator is configured to move the rotary shaft and the inner ring with respect to the support and the outer ring in a first direction parallel to the first axis so that the first contact surface contacts the second contact surface to prohibit the rotary shaft from rotating and so that precompression that acts on the plurality of balls is reduced.

    摘要： A bearing apparatus for wheels includes an outer ring, a hub shaft, rolling elements, a seal attached to a vehicle-outer-side part of the outer ring, a rotating slinger attached to the vehicle-outer-side part of the hub shaft and contacted by the seal, and a fixed slinger attached to a vehicle-outer-side outer periphery of the outer ring and contacted by the seal. An outer peripheral surface of the outer ring has a non-plated surface portion provided at a vehicle-outer-side end of the outer ring and a plated surface portion that is continuous with the non-plated surface portion. The fixed slinger has an inner cylindrical portion externally fitted over and attached to the non-plated surface portion. The seal has an inner lip that contacts the rotating slinger and an outer lip that contacts the inner cylindrical portion.
