Introduction

IntroductionBrochure

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 outer diameter.

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.
