Angular contact bearings are highly specialized bearings designed to handle combined loads involving both axial and radial forces. They find extensive use in precision engineering applications, including machine tools, aerospace components, and medical devices. With their unique design and performance capabilities, angular contact bearings significantly enhance system precision and reliability.
Angular contact bearings feature tapered roller elements positioned between an inner race and an outer race. The raceways are machined at an angle relative to the bearing axis, typically ranging from 15 to 45 degrees. This design allows the bearing to accommodate axial loads, which act parallel to the bearing axis, as well as radial loads, which act perpendicular to the axis.
Based on their construction and load capacity, angular contact bearings are classified into two primary types:
