Detailed Product Description


Needle roller bearings without inner ringNK, RNAThe needle roller bearings 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 the surface hardness be no less than HRC60, and surface roughness.Needle roller bearings with inner ringNKI,NAThe inner ring has no shoulder in this bearings. For this purpose, the inner ring, outer ring, complete set of needles and cage can be mounted respectively.NKI 9/12NA 4900NA 6900NK5/10TNNKS 8 TNRNA 4900RNA 6900NKI 10/16NA 4901NA 6901NK6/10TNNKS 10 TNRNA 152815RNA 6901NKI 12/20NA 4902NA 6902NK6/12TNNKS 12 TNRNA 4901RNA 6902NKI 15/16NA 4903NA 6903NK7/10TNNKS 14RNA 4902RNA 6903NKI 15/20NA 4904NA 69/22NK7/12TNNKS 15RNA 4903RNA6904NKI 17/16NA 49/22NA 6905NK29/20NKS 16RNA4904RNA 69/22NKI 20/16NA 4905NA 69/28NK29/30NKS 18RNA283833RNA6905NKI 22/16NA 49/28NA 69/32NK30/20NKS 20RNA 49/22RNA69/28NKI 25/30NA 49/32NA 6907NK30/30NKS 22RNA4905RNA6906NKI 32/20NA 4907NA 6908NK32/20NKS 24RNA49/28RNA69/32NKI 35/30NA 4908NA 6909NK32/30NKS25RNA4906RNA6907NKI 40/20NA 4909NA 6910NK35/20NKS28RNA 49/32RNA6908NKI 40/30NA 4910NA 6912NK35/30NKS 30RAN4907RNA 6909NKI 42/20NA 4912NA 6913NK37/20NKS 32RNA4908RNA 6910NKI 45/25NA 4913NA 6914NK37/30NKS 35RNA 4909RNA 6911NKI 45/35NA 4914NA 6915NK38/20NKS 37RNA 4910RNA 6912NKI 50/25NA 4915NA 6916NK38/30NKS 40RNA 4911RNA 6913NKI 60/25NA 4916NA 6917NK40/20NKS 43RNA 4912RNA 6914NA 4917NA 6918NK40/30NKS 45RNA 4913RNA 6915NKISNA 4918NA 6919NK42/20RNA 4914RNA 6916NKIS 8NA 4919NA 4822NK42/30RNA 4915RNA 6917NKIS 12NA 4920NA 4824NK43/20RNA 4916RNA 6918NKIS 15NA 4922NA 4826NK43/30RNA 4917RNA 6919NKIS 20NA 4924NA 4828NK45/20RNA 4918NKIS 25NA 4926NK45/30RNA 4919NKIS 35NA 4928NK47/20RNA 4920NKIS 45NK47/30RNA 4922NKIS 50NK50/25RNA 4824NKIS 60NK50/35RNA 4924NK55/25RNA 4828NK60/25RNA 4928
