Abstract: In one aspect of the present disclosure, a wheel hub assembly is provided that includes a hub body having an outboard end portion and an inboard end portion, a bearing assembly, and a seal. The seal includes a seal case and a sleeve. The hub body and seal case are rotatable relative to the sleeve. The wheel hub assembly further includes a stop of the bearing assembly configured to resist movement of the sleeve toward the outboard end portion of the hub body as the hub body, bearing assembly, and sleeve are advanced together in an inboard direction along a vehicle spindle. The stop permits the bearing assembly to transfer a force applied in an inboard axial direction against the bearing assembly, such as by tightening of a spindle nut, to the sleeve and urge the sleeve along a vehicle spindle.

Abstract: A vapor compression system including a motor having a housing and a shaft having an axis, the shaft urgable into rotational movement by the motor for powering a system component. A primary bearing and a secondary bearing are positioned in the housing for rotatably supporting the shaft, the primary bearing rotatably supporting the shaft during normal system operation. A first bearing stop and a second bearing stop are positioned on opposite sides of the secondary bearing for transmitting axial forces generated along the shaft for reaction by the motor housing during abnormal system operation. At least a portion of corresponding surfaces of each of the first bearing stop and the second bearing stop facing the secondary bearing have a protective overlying layer of material applied thereto.

Abstract: A bearing assembly is disclosed, comprising: an outer race and a plurality of rolling elements associated with the outer race. An inner race adapted to receive a shaft therein is rotatably disposed within the outer race such that the plurality of rolling elements are disposed between the inner and outer races. A cylindrical extension forming a plurality of tabs symmetrically arranged around the entire periphery of the extension is adapted to engage the shaft. A clamp collar that is installable around the cylindrical extension is defined by a circular wall with at least one threaded opening extending through the circular wall. The threaded member extends through one of the threaded openings to make contact with and apply a biasing force on one of the plurality of tabs towards the shaft when the shaft is disposed in the inner race to secure the inner race on the shaft.
