Abstract:
A bearing system for a gas turbine engine includes an outer housing and a first ball bearing assembly disposed radially inward from the outer housing relative a center axis of the outer housing. The bearing system also includes a second ball bearing assembly disposed radially inward from the outer housing and positioned axially aft of the first ball bearing assembly. The bearing system also includes a resilient member that is connected to the outer housing and compressed against at least one of a first outer race of the first ball bearing assembly and a second outer race of the second ball bearing assembly in an axial direction parallel to the center axis.
