A method of preloading a bearing wherein races are made of steel, and spacers between the races are made of a more elastic material, such as aluminum, with the desired preload being provided by preload bolts passing through the races and spacers. The preload is adjusted by applying the desired axial load to the races without the spacers installed. The distance is then measured between fixed points on the races approximately in the plane of the ball to race contact at several points around the bearing. The spacers and closure ring are then installed and the bolts are tightened until the measured distance between the fixed points on the races are reached.
