Product Description
Radial Needle Roller and Cage Assemblies
As for Model K, K D radial needle and retainer assembly, this kind of bearing only has a group of radial needle and retainer assembly. With small outside diameter size, it is suitable for the parts, where the radial sizes are specially limited, used for bearing the radial load. Model K---ZW, K---ZWD radial needle and retainer assembly is the double row radial needle and retainer assembly.As for this kind of bearing, since it has not collar, the surface of journal and the surface of hole at the housing are directly acted as rolling surface with surface hardness HRC 60 and surface roughness Ra no more than 0.63 P m.In order to satisfy the requirement of main machine, this kind of bearing can be made in split bearing, convenient for mounting. Model K…D represents as the single row split bearing and Model K--ZWD repre sents as double row split bearing.(1-1) K single-row radial needle roller and cage assembly(1-2) K...ZW double-row radial needle roller and cage assembly(1-3) K...
