Metric Series Ball Bearings (BB Series)
Drop-in Replacements For
Cross-Roller Bearings
ENDURAKOTE plating—For applications requiring
superior corrosion resistance we offer our proprietary
ENDURAKOTE® plating. 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®
plating 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® plating has been proven in critical
military, aerospace, and deep space applications.

Seals/Shields—Standard industry seals are generally
available from nitrile 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.
KAYDON BB Metric Series four-point contact ball bearings are
dimensionally interchangeable with cross-roller bearings.

Section 6–Othe r Product s

BB Series 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 fourpoint 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 bearings
provide greater design flexibility.

Temperature Capability—Standard cross-roller bearings
have a maximum full capacity operating temperature
of only 212°F. In contrast, KAYDON bearings can
operate at higher temperatures due to our heat
treating procedures.
Lubrication Options—KAYDON 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 crossroller bearings is a non-metallic composite. High
temperature and/or horizontal axis applications,
however, require non-standard materials or a nonstandard separator design. KAYDON four-point
contact ball bearings are available with separator
options to meet a wide range of applications.
Internal Fitup—KAYDON can help you optimize
internal fitup of our BB Series four-point contact ball
bearings to provide the desired operating
performance. Pre-loaded bearings are recommended
for greater stiffness, and diametral clearance is
recommended for lower torque applications.
