This webinar discusses how custom bearings can help reduce costs, streamline production, and support design innovation compared to standard bearings. The presentation covers comparing standard and custom bearings, opportunities to customize bearings through simplifying designs, right-sizing, adding features, selecting proper materials, and combining components. Supply chain strategies like packaging solutions and implementing Kanban are also reviewed to provide additional cost savings. The webinar aims to help attendees understand when custom or standard bearings are most appropriate and how customization can benefit their application.
