Abstract
A fan rotor bearing support system for a turbine engine having a power gearbox includes a first bearing assembly mounted on a proximal portion of a fan rotor of a fan section of the turbine engine and a second bearing assembly mounted on a more distal portion of the fan rotor proximal of a fan hub of the fan section. The first bearing assembly includes a four point ball bearing with limited clearance between the balls of the bearing assembly and the races of the bearing assembly to limit axial movement of the fan rotor in relation to the power gearbox. The second bearing assembly includes a low profile roller bearing to facilitate a reduction in the fan hub ratio of the turbine engine.
