As for Model K, K…D radial needle and retainer assembly this kind cf 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 net 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 h 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 represents 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.… D partial single-row radial needle roller and cage assembly

1-4) KZWD double-row radial needle roller and cage assembly

The rod-use needle roller and cage assembly is mainly used for engine, compressor and other crank-guide.

The designation of the rod-use needle roller and cage assembly is composed of letter and number. The letter KZK represents crank pine assembly and KBK represents piston pin assembly.

The needle roller and cage assembly for KZK crank pin adapts M-type cage with reliable performance. has special requirement. The surface of cage can be silver-plated or copper-coated.

The needle roller and cage assembly for KBK piston pin is different from KZK (external guide for crank pin). it is internally guided on the piston pin), thus increasing the length of needle.
