Abstract: An electrically conductive assembly prevents current flow through the raceways of a bearing disposed about a shaft and an outer ring disposed and within a bore of an outer member. An arcuate conductor has a centerline, an inner radial end engageable with the shaft or a bearing inner ring, an outer radial end and two circumferential ends spaced circumferentially apart such that an arcuate gap is defined between the two ends when the conductor is installed about the shaft or the bearing inner ring. The two circumferential ends define a gap angle about the centerline, the gap angle having a value of at least thirty degrees. At least one conductive coupler is configured to attach the conductor to the outer member, another member or the bearing outer ring such that an electrically conductive path extends through the conductor and the at least one coupler.

Abstract: The present disclosure relates to a heating, ventilation, and/or air conditioning (HVAC) unit including a condenser coil and a condenser fan assembly. The condenser fan assembly includes a first fan and a second fan, where the first fan and the second fan are each configured to operate to pull air through the condenser coil. The HVAC unit also includes a motor of the first fan including a housing and a shaft, where the motor is configured to operate to rotate the shaft in a first direction. The HVAC unit further includes a unidirectional bearing that is coupled to the shaft and a mounting assembly of the condenser fan assembly, where the unidirectional bearing is configured to block rotation of the shaft in a second direction that is opposite the first direction.

Abstract: A receiving arrangement may be utilized by a lower end of a carrier spring on a damper tube of a shock absorber of a suspension strut, in particular for a vehicle. The receiving arrangement may include a bearing unit by way of which the damper tube can twist relative to the carrier spring about a longitudinal axis of the suspension strut. The bearing unit may include an upper bearing ring and a lower bearing ring, which bearing rings may be configured so they can slide on each other to form an axial bearing and a radial bearing between the carrier spring and the damper tube.
