This lubrication system eliminates the thermal induced bearing torque effect due to viscosity. The retainer contains multiply segments with an inner race guided configuration, an alternative ball pocket cross section design and a ball pocket slotted configuration (1) to reduce the thermal induced effects due to coefficient of thermal expansion mismatch between the raceway and the retainer material (2) to enhance the producibility of the retainer due to out-of-round, out-of-flatness and torsional wrap, and (3) to reduce the manufacturing cost.
