A system includes a bearing assembly configured to be coupled to a compressor of a gas turbine engine and to receive an end of a torque shaft assembly, a bearing housing, and a circumferential bearing. The circumferential bearing includes a split race and a ball disposed within the split race. The circumferential bearing may be configured to be removed from the bearing housing without having to remove the torque shaft assembly from the compressor.

1. A system, comprising: a bearing assembly configured to be coupled to a compressor of a gas turbine engine and to receive an end of a torque shaft assembly, comprising: a bearing housing; anda circumferential bearing comprising: a split race, wherein the split race comprises an annular portion that extends in an axial direction along an longitudinal axis of the split race and a flange portion that extends in a radial direction away from the longitudinal axis, and wherein the split race is split both in the axial direction along the longitudinal axis and in the radial direction away from the longitudinal axis; anda ball disposed within the split race;wherein the split race of the circumferential bearing is configured to be removed from the bearing housing without having to remove the torque shaft assembly from the compressor. 2. The system of claim 1, wherein the split race comprises at least two pieces. 3. The system of claim 1, wherein the ball is configured to be installed between the at least two pieces of the split race prior to installation of the circumferential bearing on the bearing housing. 4. The system of claim 1, wherein the annular portion of the split race comprises an inner surface that interfaces with an outer surface of the ball, and an entirety of the inner surface interfaces with the outer surface of the ball. 5. The system of claim 4, wherein both the inner surface of the annular portion and the outer surface of the ball are coated with tungsten carbide. 6. The system of claim 1, wherein the flange portion comprises a plurality of thru holes, the bearing housing comprises a plurality of housing thru holes that align with the plurality of thru holes, and the bearing assembly comprises a plurality of bolts, wherein each bolt of the plurality of bolts extends thru a respective thru hole of the plurality of thru holes and a respective housing thru hole of the plurality of housing thru holes to couple the circumferential bearing to the bearing housing. 7. The system of claim 6, wherein the plurality of bolts extend thru the flange portion and the bearing housing in the axial direction parallel to the longitudinal axis. 8. The system of claim 6, wherein the flange portion and the bearing housing form a rabbet fit coupling when coupled together. 9. The system of claim 6, wherein the flange portion comprises a plurality of tapped holes, wherein the tapped holes are configured to be utilized as jack screw holes in disassembly of the circumferential bearing from the bearing housing. 10. The system of claim 6, wherein the bearing housing comprises a surface that interfaces with the flange portion of the split race, and the surface comprises a plurality of dimples. 11. The system of claim 1, comprising the gas turbine engine having the compressor, the torque shaft assembly, and the bearing assembly. 12. A circumferential bearing, comprising: a split race comprising an annular portion that extends in an axial direction along a longitudinal axis of the split race, a flange portion that extends in a radial direction away from the longitudinal axis, and a plurality of thru holes on the flange portion and each thru hole is configured to receive a respective bolt of a plurality of bolts, wherein the split race is split both in the axial direction along the longitudinal axis and in the radial direction away from the longitudinal axis, and the split race comprises at least two pieces; anda ball disposed within the split race;wherein the split race of the circumferential bearing is configured to be removably coupled, via the plurality of bolts, to a bearing housing of a torque shaft assembly coupled to a compressor of a gas turbine engine. 13. The circumferential bearing of claim 12, wherein the ball is configured to be installed between the at least two pieces of the split race prior to removably coupling the circumferential bearing to the bearing housing. 14. The circumferential bearing of claim 12, wherein the annular portion of the split race comprise an inner surface that interfaces with an outer surface of the ball, and an entirety of the inner surface interfaces with the outer surface of the ball. 15. The circumferential bearing of claim 14, wherein both the inner surface of the annular portion and the outer surface of the ball are coated with tungsten carbide. 16. A method of removably attaching a circumferential bearing to a bearing housing disposed on a compressor of a gas turbine engine and coupled to a torque shaft assembly, comprising: disposing a ball between at least two pieces of a split race to assemble the circumferential bearing;aligning a plurality of thru holes of a flange portion of the split race with a plurality of housing thru holes of the bearing housing; andsecuring the flange portion of the split race to the bearing housing via a plurality of bolts each disposed respectively in an axial direction through the plurality of thru holes and the plurality of housing thru holes. 17. The method of claim 16, comprising: unfastening the plurality of bolts; anddetaching the circumferential bearing from the bearing housing without removing the torque shaft assembly from the compressor.
