RBC produces an extensive heavy duty needle roller bearing product
line from 1 inch outer ring diameter to 12 ¼ inch outer ring diameter.
RBC has the capability to manufacture special designs up to a 39 inch
The RBC SJ series of Pitchlign® heavy duty needle roller bearings
are supplied in standard envelopes in both sealed and unsealed configurations.
There are eight possible seal configurations. The seals can include
double or single seal with the seal lip turned inward or outward.
The seal can be mounted in the radius end of the ring or the chamfered
end of the ring for optimum mounting variations.
RBC’s patented TJ TandemRoller® heavy duty needle roller bearings
increase the capacity of the standard Pitchlign® SJ series from 10%
to 40% while maintaining the standard SJ envelope dimensions. The
TJ design gives the heavy duty needle roller bearing 37% to 200% greater
life over a standard single pocket bearing. These bearings are also
available in sealed and unsealed configurations.
RBC heavy duty needle roller bearings present a wide variety of designs.
The TJ TandemRoller® and Pitchlign SJ Series heavy duty needle roller
bearings are offered in a double-row design. The TJ and SJ roller
bearings can also be matched with an inner ring or run directly on
a shaft. RBC inner rings can be used separately or as an inner race
for complimentary SJ or TJ roller bearings. The inner rings range
are through hardened and precision ground.
The RBC SJ and TJ heavy duty needle roller bearing designs are easy
to install and are especially beneficial in compact designs because
of their high load capacity and small sectional height. The caged
rollers allow for the RBC heavy duty needle roller bearings to be
used in high speed applications.
