440C Ring Material
Eliminates thin dense
chrome plating while
providing corrosion
resistance protection
and maintaining the
precision, tolerance,
and finish.
440C Spacer Balls
Spacer balls are smaller
than load balls by 0.5-1%.
In pre-loaded bearings, other separator
options may generate particle shedding –
resulting in erratic torque fluctuations.
General Features and Technical Specifications
Low Torque Seals or Non-contacting Shields
Engineering assistance provided for optimum performance when evaluating
application requirements.
Low Torque/High Stiffness
Internal design characteristics
result in an optimized
bearing solution for demanding
low torque, high stiffness
applications.
More than just bearings...
• Bearing fit-ups are factory-optimized and pre-loaded for
repeatable stiffness and torque.
• Integrated assemblies are simply bolted in place, eliminating
individual bearing fit-up time and assembly errors in the field.
• Most integrated assemblies are integrally shielded to prevent
contamination and ensure long bearing life.
• Superior performance compared to conventional approach
to bearing assemblies.
• Lower total cost of ownership.
Integrated Assemblies
Silicon Nitride Load
Balls (Si3N4)
Si3N4 balls promote a
much lower coefficient of
friction versus steel balls,
therefore providing
enhanced survivability
under marginal lubrication.
Si3N4 balls also have a
higher modulus of
elasticity – 50% higher
than steel balls to provide
higher stiffness.
SuperDuplexTM Design
A one-piece ring on a double row set design offers
improved ring stiffness and reduced distortion,
improved face-to-face runout, and parallelism.
As a result, the bearing offers superior accuracy
and performance reliability, including improved
alignment and ease of next level assemblies.
RBC Bearings has been producing bearings in the USA since 1919.
RBC offers a full line of bearings for industrial, aerospace,
and defense, including unique custom configurations.
