BB series metric thin-section ball bearings

BB series metric thin-section ball bearings are based on four-point contact ball bearings. They are designed to match the bore diameter and width of common crossed roller bearings. BB series bearings offer additional features not typically found in standard crossed roller bearings, providing beneficial design flexibility. These bearings can be further customized to meet specific application needs.
