摘要: A method of and apparatus for adjusting the preload of an anti-friction bearing is disclosed. A compressive load is applied to the opposite transverse faces of the outer races of a linear bearing by hydraulic or pneumatic cylinders. While the bearing assembly is held in compression, a test force is applied to one end of the inner race or slide in a direction parallel to its constrained direction of travel to cause the slide to move through the bearing at a steady rate of travel. While the slide is in motion, rolling friction characteristics are measured by a force gauge. The resulting force gauge measurement corresponds to a particular bearing preload. The compressive load is re-adjusted as necessary under control of a closed-loop feedback system to achieve a value in an acceptable preload range, followed by final assembly of the bearing with a layer of high-strength adhesive applied to the overlapping flanges of the bearing to create a bond having sufficient strength with which to retain that preload for the anticipated service life of the bearing.
