Abstract
An assembly tool (104) for positioning the rolling elements (150, 155) of a bearing assembly (100) during a preloading operation includes a roller seating actuator (400) configured to be removably coupled to a portion of the bearing assembly during the preloading operation, and a roller seating ring (420) movably coupled to the roller seating actuator. The roller seating ring includes a distal end (440) configured to engage an end of a rolling element of the bearing assembly. A biasing member (460) is positioned between the roller seating actuator and the roller seating ring and biases the roller seating ring away from roller seating actuator such that the distal end of the roller seating ring engages and presses the rolling element axially into engagement with a rib (145) of a race of the bearing assembly.
