The dynamic capacities listed represent the maximum capacities based on 52% curvature of the inner and outer raceways in accordance with ABMA and ISO standards; however, since a majority of miniature and instrument bearings are lightly loaded and operate at low to moderate speeds where low torque is a primary objective, the internal geometry for a particular part number in current production/inventory may be different. We recommend that if your specific application will exceed 20% of the rated capacity listed than you should contact our applications engineering department for assistance in bearing life calculations to meet your application requirements.
