Abstract
A bearing assembly for a gas turbine engine rotor includes, in an exemplary, an inner race, an outer race assembly, and a rolling element. The outer race assembly includes a body, a plurality of first springs attached to the body, and a plurality of second springs. Each first spring is radially aligned with a corresponding second spring forming a spring pair. The outer race assembly also includes a plurality of connecting members. Each connecting member extends between and connects a first end of the first spring and a first end of the second spring of said spring pair. The outer race assembly further includes a flange with each second spring attached to the flange.
