Abstract: A bearing assembly for use in a gas turbine engine is provided. The bearing assembly includes a bearing retainer having an inner portion, an outer portion spaced radially apart from the inner portion, and an intermediate portion connecting the inner portion and the outer portion, wherein the inner portion and the outer portion define a space there-between. The bearing assembly also includes a bearing housing having an extended portion positioned within the space. The bearing assembly also includes a locking assembly comprising a locking plate and an axial keyway that extends axially away from the locking plate. The locking plate is coupled to the bearing retainer and the axial keyway is coupled to the extended portion of the bearing housing.
