Needle roller bearing is cylindrical roller bearing; relate to its diameter the roller is both thin and long. This roller called a needle roller. The bearing still has a high load capacity although the smaller cross-section.
NA4822 Bearings are supplied in standard envelopes in both sealed and unsealed configurations.
NA4822 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 heavy duty needle roller bearings to be used in high speed applications.
