⊙The outer ring of drawn cup needle roller bearing is punched with the steel sheet. It has the small sectional height and thelarge load carrying capacity and is suitable for economic mass production.
⊙The interference fit between outer ring and bearing housing is applied to this kind of needle roller bearing without axialfixing device. Even for the condition of high load, it fully maintains bearing function either. In addition, with the large greasestorage capacity, it is unnecessary to add grease for a long-term operation.
⊙Since one end of the close-end bearing is sealed, it is suitable for the end of shaft with bearing the small axial sliding
force.
⊙Model HK, TA, TLA, open-end drawn cup needle roller bearings with retainer
⊙Model BK close-end drawn cup needle roller bearing with retainer
⊙Model SCE, BA, J, JH, drawn cup needle roller bearings (Inch series).
⊙The rod-use needle roller and cage assembly is mainly used for engine, compressor and other crankguide.
⊙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. It 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.
⊙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 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.

⊙Thrust Parallel Roller Bearing, Series 811, 812, 893, 874, 894
⊙The 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 roller bearing is the one only supporting the axial load in one direction. It is used as the bearing allocation having the good rigidity and axial small space.
⊙Thrust Collar, Shaft Ring and Seat Ring
⊙Thrust Collar, Series AS, LS, GS, WS, ZS, TRA, TRB, TRC TRD.
⊙Series 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.
⊙Series 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.
⊙As 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.
