¡ñthe drawn cup needle roller clutch is the overriding clutch (one-way clutch), composed of the outer ring punched with the high-quality steel sheet, plastic retainer, spring and needles, used for transferring one-way torque.
¡ñthe drawn cup needle roller clutch has not the load carrying feature by itself. However it can play the action in combination with model hk and bk drawn cup needle roller bearing.
¡ñthe drawn cup needle roller clutch is the block bearing either withstanding the radial load or transferring torque.
¡ÑAs 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.
¡ÑAs 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 m.
¡ÑIn 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.

¡ñthe needle roller bearing without inner ring is suitable for the parts of which the radial size is limited. Because of no inner ring, the surface of shaft journal fitted with it is acted directly as rolling surface. It is requested that the surface hardness be no less than hrc60, surface roughness, no more than 0.63¦ìm. This kind of bearing does not limit the axial shift of shaft and housing and has high limiting rotational speed.
¡ñthe inner ring has no shoulder in this bearing. For this purpose, the inner ring, outer ring, complete set of needles and cage can be mounted respectively. This bearing does not limit the axial shift of shaft and outer housing. Since the cage separates the needles so as to reduce friction. It can be used for the parts with high rotational speed.

¡ñthe thrust needle roller bearing or thrust parallel roller bearing is such a manner that the needles (rollers) with cage are set up in the space between rollway and collar and the cage reliably guides and clamps a lot of rolling bodies. There is a little difference among the rolling bodies in the same set. The thrust needle roller bearing or thrust parallel
¡ñseries as thrust collar is punched with the high quality steel spring plate in thickness of 1mm and quenched and polished. When the surface of the adjacent parts can not be acted as rollway, although it has a good rigidity, series as collar shall play its full action.
¡ñseries gs, ws, ls thrust collars are made of bearing steel with the quenching process. The outer surface of gs seat ring and the inner surface of ws shaft ring are ground. Series ls thrust collar is an economic product with machining the outer and inter surfaces.
¡ñas for series zs thrust collar, when it is required for assembly to set up the bearing as bidirectional location, the series zs collar can be used as axial location or seat hole location.
