Needle Roller Bearings


Needle roller bearings have cylindrical rollers with diameters much smaller compared to their lengths. These bearings offer great rigidity and are useful for applications were the radial space between the housing and the shaft is limitied. Sometimes, to conserve space, the inner ring may be omitted and the needle rollers ride directly on the shaft.
