BB series metric thin section ball bearings are based on a four-point contact ball bearing. They are designed to match the bores and widths of common cross-roller bearings. With additional features not commonly available in standard cross-roller bearings, BB series bearings provide beneficial design flexibility. The bearings can be further customized to meet specific application needs.​

Features and benefits

• Thin cross section
  In applications where space is limited, BB series metric thin section bearings offer a very compact design.
• Lightweight
  BB series bearings can enable significant weight savings, which may result in cost savings for the overall application.
• Dimensionally interchangeable with cross-roller bearings
  With additional flexibility in design, BB series bearings should be considered as a practical alternative to the use of cross-roller bearings.
• Low friction
• High stiffness
• High running accuracy
