A system for the axial retention of a holding ring for a bearing for guiding in rotation a rotary shaft of a turbomachine is disclosed. The system includes an annular bearing support and a bearing holding ring that is borne by the annular bearing support. The bearing holder ring includes an upstream ring configured to be brought into contact with the bearing support and a downstream ring that is elastically deformable. The bearing support has a first axial retention element, and the bearing holding ring has a second axial retention element. The first and second axial retention elements are configured to cooperate with one another to axially retain the bearing holding ring in the event of damage to the downstream ring.

A motor includes a bearing having a rolling member disposed between an inner ring and an outer ring, a spring connected to the outer ring, and a pusher connected to the spring and configured to move to a first position spaced apart from the inner ring by the spring. The pusher is further configured to move to a second position at which friction with the inner ring is caused by a pressure of air. The inner ring is spaced apart from the rotating shaft by a gap between the inner ring and the rotating shaft when the pusher is at the second position.

This disclosure provides a strut bearing for MacPherson strut suspensions including a cap, a guide ring, and a bearing arrangement located between the cap and the guide ring. The cap comprises a first hook on an inner side in a radial direction of the strut bearing and a third hook on an outer side in the radial direction, and the guide ring comprises a second hook on the inner side engaged with the first hook and a fourth hook on the outer side engaged with the third hook; the first and second hooks form an inner snap connection extending circumferentially, and the third and fourth hooks form an outer snap connection extending circumferentially.

An integrated journal bearing (IJB) includes a shaft extending in an axial direction, a housing through which the shaft extends in the axial direction, the housing surrounding the shaft in a radial direction, an active magnetic bearing (AMB) arranged within the housing and surrounding the shaft in the radial direction, and at least a first fluid film journal bearing (JB) arranged within the housing and surrounding the shaft in the radial direction. The first JB is axially adjacent to the AMB such that first JB and the AMB do not share a common radial clearance, while both are commonly flooded with oil. A controller in signal communication with the AMB can be variously configured to supply current thereto to operate the AMB by controlling a magnetic force generated thereby.
