Abstract
The method includes sliding a first shim onto the support shaft until it abuts a shoulder. The first shim has a predetermined thickness. A bearing is then slid onto the tapered surface and a lock nut is tightened onto the threaded portion of the shaft. As the lock nut contacts the inner race of the bearing it causes the inner race to contact the first shim and also to radially expand outwardly, thereby preloading the bearing. The outer race of the bearing is then connected to a motor and the motor is operated at a predetermined, constant speed. The torque required to rotate the outer race of the bearing is measured and compared to a predetermine torque range to determine if the bearing is precisely preloaded.
