For more products and information, please visit the official website  The 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 0.63pm. This kind of bearing does not limit the axial shift of shaft and housing and has high limiting rotational speed.The 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.  Shaft DiameterBearing DesignationMass ApproxBoundary DimensionsBasic Load RatingLimiting SpeedCurrent CodeOriginal CodeFwDCDynamicStaticOilmmgmmNrpm5NK5/10TN 2.9510102100140036780NK05/08  5108   NK05/10TN-OH  510122350192039000NK05/12TN 3.75101230002650390006NK06/10  612102600220037000NK06/10TN  612102600220037000NK06/12TN 5.7612123350315037000RNA6X13X8TN  6138   7NK07/10 6.9714102850265034000NK07/12 8.27141236503600340007.8RNA7.8169  7.8169   8NK8L 12TN 8.3815123950410032000NK08/12 8.7815123950410032000NK08/16 12815165100580032000NK08/16TN  815165100580032000RNA8X19X9  8199   RN8X14X8  8148   RNA496  81510   RNA8X15X10TN  81510   9NK09/12 10.391612   10NK10/12TN462409K101017124750530029000 562409716.61017154860710029000NK10/10  101710   NK10/12  101712   NK10/16  1017166200780029000NK10/16TN  1017166200780029000NKS10  101913580060002900012NK12/12TN64409711.81219126000640027000 562409815.41219156400710027000NK12/16 16.8121916820098002700014NK14/164624900K20.8142216101001150025000NKS14 2714251614001380024000RNA4900462490024.41422138500900025000RNA6900663490029.1142222128001560025000NK14/12  142212   NK14/20  14222012800156002500015NK15/12644800K18.515231286001100021000RNA152815 31.7152815136001720024000 7948/1516.1152212820098008500Shaft DiameterBearing DesignationMass ApproxBoundary DimensionsBasic Load RatingLimiting SpeedCurrent CodeOriginal CodeFwDCDynamicStaticOilmmgmmNrpm5NK5/10TN 2.9510102100140036780NK05/08  5108   NK05/10TN-OH  510122350192039000NK05/12TN 3.75101230002650390006NK06/10  612102600220037000NK06/10TN  612102600220037000NK06/12TN 5.7612123350315037000RNA6X13X8TN  6138   7NK07/10 6.9714102850265034000NK07/12 8.27141236503600340007.8RNA7.8169  7.8169   8NK8L 12TN 8.3815123950410032000NK08/12 8.7815123950410032000NK08/16 12815165100580032000NK08/16TN  815165100580032000RNA8X19X9  8199   RN8X14X8  8148   RNA496  81510   RNA8X15X10TN  81510   9NK09/12 10.391612   10NK10/12TN462409K101017124750530029000 562409716.61017154860710029000NK10/10  101710   NK10/12  101712   NK10/16  1017166200780029000NK10/16TN  1017166200780029000NKS10  101913580060002900012NK12/12TN64409711.81219126000640027000 562409815.41219156400710027000NK12/16 16.8121916820098002700014NK14/164624900K20.8142216101001150025000NKS14 2714251614001380024000RNA4900462490024.41422138500900025000RNA6900663490029.1142222128001560025000NK14/12  142212   NK14/20  14222012800156002500015NK15/12644800K18.515231286001100021000RNA152815 31.7152815136001720024000 7948/1516.1152212820098008500Shaft DiameterBearing DesignationMass ApproxBoundary Dimensio
