A jet engine subassembly. The high pressure (HP) turbine includes a ball bearing assembly whose inner race is attached to the HP turbine shaft. The outer race takes radial loads through radially-extending tie rods which pass through the HP turbine nozzle vanes and are connected to the combustor's outer casing. The outer race takes axial loads through a support cone which is attached to the combustor diffuser's radially inner duct through an intermediate forward segment of the combustor inner casing. This eliminates the need for a heavy turbine frame. The ball bearing is the thrust bearing, and does not experience thermal axial growth. This allows the use of unshrouded sloped HP turbine blades.
