High precision bearingsare applied to superior accuracy, high running speeds, long lifeand limiting of noise and vibration are critical. High precision bearings are applied on machine tools, such as machining centers and grinders. Other precision bearings applications include aircraftand robotics. There are two major precision bearing ratings organizations. ABEC, which stands for Annular Bearings Engineer Committee, which determines standards for the AFBMA, Anti-Friction Bearing Manufacturers association, and ISO or International Standards Organization.
