Needle Roller / thrust Ball Bearings, Thrust Bearing With A Cage

The NKX series combined bearings consist of a radial needle roller bearing and a thrust ball bearing. The steel ball and cage thrust assembly of the thrust ball bearing is the same as that of the unidirectional thrust ball bearings in the 511 series, allowing for relatively high-speed operation. Axial positioning in one direction is achieved through the outer ring flange. The steel ball-cage assembly and the shaft washer can be separated for installation. As there is no sealing structure to keep grease inside the bearing, lubrication with oil is required. These bearings are standardly supplied without a pressed steel shield.
