BB Series Thin Section Bearings Are Available to Match the Bores and Widths of Common Cross-Roller Bearings.

When factors such as cost, availability, corrosion resistance, tighter tolerances, torque, seal/shield options, and temperature resistance are important in your application, it pays to consider BB Series thin section four-point contact metric ball bearings as an alternative to cross-roller bearings. The additional design flexibility they offer can often help you achieve your design objectives with optimum performance and economy.

Additional features not commonly available in standard cross-roller bearings, include a protective package for corrosion resistance, custom sealing for extreme environments, application-specific lubrication and temperature capability.

Optimize Your Design Options

With additional features not commonly available in standard cross-roller bearings, BB Series thin section bearings provide greater design flexibility.

Endurakote® coating--For applications requiring superior corrosion resistance, we offer our proprietary Endurakote® coating. This thin, dense chrome plating gives AISI 52100 bearing material corrosion resistance equal to or better than that of AISI 440C stainless steel. Unlike many traditional chrome platings, the extremely hard surface of Endurakote® coating doesn't peel and flake from the bearing race under stress, so corrosion resistance is retained and surface wear is minimized. The performance of Endurakote® has been proven in critical military, aerospace, and deep space applications.

Seals/Shields--Standard industry seals are generally available from Buna-N rubber. Kaydon can also provide custom seals manufactured from silicone or Viton® materials for applications where high temperature or extreme environments are likely to be encountered.

Temperature Capability--Standard cross-roller bearings have a maximum full capacity operating temperature of only 212°F. In contrast, Kaydon’s heat treating procedures allow Kaydon bearings to operate at higher temperatures.

Lubrication Options--Kaydon Bearings Corporation offers a full range of lubricants, allowing you to optimize bearing performance in a range of applications with special requirements for moisture resistance, hot or cold temperatures, vacuum, and low torque.

Separators--The common roller spacer for many cross-roller bearings is a nonmetallic composite. High temperature and/or horizontal axis applications may require non-standard materials or a non-standard separator design, however. Kaydon four-point contact ball bearings are available with separator options to meet a wide range of applications.
