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. The Pitchlign SJ Series heavy duty needle roller bearings are offered in a double-row design. The SJ roller bearings can also be matched with an inner ring or run directly on a shaft.
The RBC SJ 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.
