Detailed description

Item No:K3X5X9TN Radial Needle Roller and Cage Assemblies 3x5x9mm

The needle roller and cage assembly is an independent bearing element. The each of needle roller is

guided and caged accurately by the cage. It has the highest load carrying capacity and the high rigid design in the smallest structure and space. The wide distance between two guiding surfaces of cage ensures the accurate guide of needle roller and cage assembly.

Needle roller and cage assembly is suitable for the place where the shaft and housing bore are acted as

the raceway. Under the geographic accuracy shaft and housing bore raceway, the highest rotation precision

can be obtained.

The working clearance in bearing location is dependent on the tolerance of inner and outer raceways,

needle roller difference and working temperature.

As for Model K, KD 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 KZW, KZWD 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 0.63m.

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 KZWD represents as double row split bearing.
