The bearing assembly encircles an upper end portion of the strut member. The mounting bracket is configured to receive the bearing assembly with mounting bracket encircling the upper end portion of the strut member and further configured to attach to a portion of a vehicle body assembly of a vehicle. The noise isolating member is installed below the mounting bracket and along a surface of the bearing assembly reducing noises transmitted from the vehicle strut assembly to the portion of the vehicle body assembly.

Redundant helicopter pitch change bearing

An aircraft rotor system includes a rotating pitch change shaft which rotates about an axis, a translating element disposed within the rotating pitch change shaft and movable along the axis and a pitch change bearing assembly which transfers movement of the translating element to the pitch change shaft. The pitch change bearing assembly includes a primary bearing and a secondary bearing coupled to the rotating pitch change shaft via the translating element when the primary bearing is in a first mode. A thrust shoulder is coupled to the translating element. The thrust shoulder is movable into engagement with the secondary bearing in response to failure of the primary bearing such that in a second mode, movement of the translating element is primarily transferred to the pitch change shaft via the secondary bearing.

Turbocharger dual ball bearing system

A bearing system for a turbocharger includes a bearing housing having a first end and a second end, with the bearing housing defining a central passageway. A first ball bearing and a second ball bearing are received by the bearing housing. The second ball bearing is spaced from the first ball bearing.

Vacuum pump

A pump insert (50) for supporting a rotor (14) of a pump comprises an annular resilient support (52) for engaging the body (26) of the pump, the support (52) extending about a rolling bearing (10) having an inner race (12) for engaging the rotor (14), an axially preloaded outer race (16) fixed to the support (52), and a plurality of rolling elements (18) located between the races. During assembly, the rolling bearing (10) can be accurately positioned within the support (52) so that there is a very low tolerance stack-up when the insert (50) is fitted to the rotor (14). Consequently, the position of the rotor (14) will hardly change, if at all, when the rolling bearing (10) is replaced during servicing of the pump.
