combined ball roller type NKX series NKX20 needle roller thrust rolling bearings NKX 20 Z size 20x30x30mm

 

Combined needle roller bearings comprise a radial needle roller bearing, which is combined with an axial bearing component. These bearings can support radial as well as axial loads with just one bearing and permit locating bearing arrangements with only a small radial design envelope section. They are suitable, for example, where radial and axial loads are present and simple axial contact washers are no longer able to support the axial loads on account of their size, high speeds or inadequate lubrication, and other locating bearings require too much installation space.
