The ball bearings listed in these tables are available in a variety of different grades. As discussed, ABEC and ISO standards only cover part of the overall bearing picture, particularly for more demanding applications.Beyond the basic dimensions and tolerances of a bearing, characteristics such as raceway finish, cage quality, ball matching and consistency of internal geometry can affect the performance of an individual bearing in its application. These characteristics are generally determined by the level of sophistication of the equipment used to manufacture the bearings. This sophistication, in turn, affects the cost and availability of the bearing. It is recommended that demanding applications for bearings are discussed with a bearing engineer (contact).
