SUMMARY
The discussion centers on determining the maximum permissible preload for angular contact bearings used in spindle applications, with a focus on thermal expansion considerations. Users recommend consulting the SKF and NSK websites for relevant resources, including preload guidelines and bearing selectors. The SKF site provides minimum preload recommendations to prevent premature bearing failure, while users emphasize the importance of calculating maximum preload based on dynamic and static load limits. The lack of specific numerical data for preload versus axial displacement and rotational speed is noted as a significant gap in available resources.
