In addition to the standard RBC Thin Section Ball Bearings, RBC will also manufacture specially designed bearings for specific applications. RBC Sales Engineers and Customer Service Representatives are available for consultation.
Tool Table Using
a 4-point contact RBC Thin Section Ball Bearing provides stiffness for
accurate positioning as well as carrying multiple loads. RBC supplied
this assembly as shown.
For use in an aerial
camera assembly, an extra-light, low torque bearing was required. By
redesigning a standard RBC Thin Section Ball Bearing 4-point contact
design, the overall assembly weight was lowered from 7 lbs. to 3.8 lbs.
In addition to weight reduction, this design, also reduced the running
torque below 1 in.-lbs. with the starting torque below 2 in.-lbs.
Running at slow
speeds with combined load carrying capabilities and minimal space determined
the use of this 4-point RBC Thin Section Ball Bearing. RBC supplied
this assembly as shown.
A duplex pair of
angular contact RBC Thin Section Ball Bearings was designed for an airborne
radar system. This bearing application required combined load carrying
capabilities, low temperature compatibility, and relatively low torque.
Different from a standard Thin Section, this duplex bearing was designed
with one outer ring and two inner rings with a slight preload. This
design provided low torque and multiple loading capabilities.
An RBC Thin Section
Ball Bearing designed with a gear integrated with the inner ring, achieved
both a significant weight reduction and improved accuracy as well as
simplicity of assembly. This bearing is used in a radar antenna drive
which has limited space available for its support bearing. Coil springs
were used as spacers between balls to lower bearing torque and further
A preloaded duplex
pair of angular contact RBC Thin Section Ball Bearings were designed
to meet the low torque and corrosion resistant requirements in a combined
load application. Designed for an instrument gimbal assembly in a missile,
the duplex pair of bearings are subjected to combined radial, axial,
and moment loads. These special RBC Thin Section Ball Bearings have
a light preload and were manufactured with integral shields as part
of the rings.
included minimal radial runout, low torque, corrosion resistance, combined
load capabilities and vacuum operation capabilities. Special designed
duplex stainless steel angular contact RBC Thin Section Ball Bearings,
provided the capabilities required.
A bearing was required
which would take radial, axial, and moment loading, to support an aircraft
gun turret. It was desirable to have a bearing match the coefficient
of expansion of the aluminum with a split inner ring and special balls
to absorb shock and vibration loading. This bearing performed at 25%
of the torque of the steel bearings previously used.
Automated Test Equipment
test equipment required an RBC Thin Section Ball Bearing to accurately
position a table. In this application the bearing oscillates to ± 10
degrees, and was designed as a 4-point contact bearing.
A low torque, high
stiffness, multiple load capacity, corrosion resistant bearing was required
for an airborne turret azimuth drive assembly. For this application
a duplex pair of angular contact RBC Thin Section Ball Bearings was
designed with toroid separators and stainless steel rings. This design
maintained low torque, but still allowed multiple load carrying capabilities.
