Machined needle roller bearing-NEY（DuangDong）Bearing Industry Co.,LTD

& nbsp; features these series include radial needle roller bearings and roller bearing components that can bear axial force. they can bear high radial force and axial force in one direction, while nkib bearings can bear axial force in two directions, which can be used as positioning bearing or semi positioning bearing, as shown in Figure 1 .

O: P > O: P > figure 1 & nbsp; dynamic bearing capacity in radial and axial direction

the combined needle roller bearing is X-life bearing. These bearings have optimized raceway surfaces. so it has higher bearing capacity and longer rated life. the existing design is as follows: ■ needle roller / thrust ball bearing ■ needle roller / thrust cylindrical needle roller bearing needle roller / angular contact ball bearing. these series are very compact in radial direction without inner ring. However, they require that the raceway of the shaft be hardened and ground. bearings NX and NX.. - Z include thrust ball bearings and housings filled with balls. Nkx and Nkx.. - Z series include axial bearing parts, which are composed of ball and pressed steel plate cages or nylon cages. Nkx.. - Z including thrust bearing parts with cover. the outer ring has lubricating oil groove and lubricating oil hole for lubricating. NX and Nkx adopt oil lubrication. The cover NX has lubrication holes. NX.. - Z and Nkx.. - Z adopt grease lubrication. the thrust bearing parts adopt lithium-based composite grease ga08 . There are no lubrication holes in the cover. these series have no inner ring, so the radial dimension is very compact. However, they require that the raceway of the shaft be hardened and ground. series nkxr and nkxr.. - Z have axial bearing parts, which are composed of roller and nylon cage components. nkxr.. - Z including thrust bearing parts with cover. the outer ring has lubricating oil groove and lubricating oil hole for lubricating. nkxr oil lubrication. nkxr.. - Z suitable for grease lubrication. The thrust bearing parts are lubricated with lithium base compound grease ga08 . there is no lubrication hole in the cover.
