bearings (CRBs) are in linear contact with the raceways. They have a high load capacity when subjected to primarily radial loads. Because of the low friction between the rollers and the ring ribs, these bearings are suitable for high-speed rotation.Single-row cylindrical roller bearings with cage are units comprising of solid inner and outer rings and cylindrical roller and cage assemblies. The outer rings have rigid ribs on both sides or no ribs, and the inner rings have one or two rigid ribs or are designed without ribs. The cage prevents the cylindrical rollers from contacting each other during rolling. As a cylindrical roller bearing supplier, we offer roller bearings with or without a cage.Two-row, or double-row, cylindrical bearings are designed for additional strength in carrying radial loads. These bearing types are interchangeable so the dimensions and diameter under the rollers (NNU style) and diameter over the rollers (NN style) are held to an ISO/DIN standard. Interchangeability is designed for the ring without the rollers to allow interchange with competitor inner rings.Bearing No.Boundary dimensionsBasic load rating(kN)Limiting speedsMassmmDynamicStaticrpmKgdDBrs minrs1 minCrCorGreaseOil≈N1000 SeriesN10052547120.60.315.114.116,00019,0000.091N100630551310.619.719.614,00016,0000.128N100735621410.622.623.212,00015,0000.176N100840681510.627.32911,00013,0000.217N100945751610.631349,90012,0000.276N101050801610.632368,90011,0000.291N10115590181.1137.5448,2009,7000.435N10126095181.114048.57,5008,8000.467N101365100181.1141517,0008,2000.477N101470110201.1158.570.56,5007,6000.689N101575115201.116074.56,1007,1000.727N101680125221.1172.590.55,7006,7000.965N101785130221.1174.595.55,4006,3001.01N101890140241.51.1881145,1005,9001.31N101995145241.51.190.51204,8005,6001.38N1020100150241.51.1931264,6005,4001.43N10211051602621.11051424,3005,1001.81N10221101702821.11311744,1004,8002.3N10241201802821.11391913,8004,4002.4N10261302003321.11722383,4004,0003.63N200 seriesN2084080181.11.143.5439,40011,0000.37N2094585191.11.146478,4009,9000.423N2105090201.11.148517,6009,0000.46N21155100211.51.15862.56,9008,2000.626N21260110221.51.568.5756,4007,6000.802N21365120231.51.58494.55,9007,0001N21470125241.51.583.5955,5006,5001.1N21575130251.51.596.51115,1006,0001.21N2168014026221061224,8005,7001.47N2178515028221201404,5005,3001.83N2189016030221521784,3005,0002.25N21995170322.12.11661954,0004,7002.72N220100180342.12.11832173,8004,5003.26N221105190362.12.12012413,6004,3003.87N222110200382.12.12402903,4004,0004.54N224120215402.12.12603203,2003,7005.46N22613023040332703402,9003,4006.17N2200 seriesN22084080231.11.158628,50010,0000.48N22094585231.11.161.5687,6009,0000.52N22105090231.11.16473.56,9008,1000.56N221155100251.51.175.5876,3007,4000.758N221260110281.51.5961165,8006,8001.04N221365120311.51.51201495,4006,3001.37N221470125311.51.51191515,0005,9001.44N221575130311.51.51301624,7005,5001.52N22168014033221471864,4005,1001.89N22178515036221702184,1004,8002.39N22189016040221972483,9004,6003.04N221995170432.12.12302983,6004,3003.71N2220100180462.12.12583403,5004,1004.48N2222110200532.12.13204153,1003,7006.43N2224120215582.12.13504602,9003,4008.03N222613023064333805302,6003,10010N300 seriesN3084090231.51.558.5578,0009,4000.643N30945100251.51.574717,2008,4000.857N31050110272287866,5007,7001.11N3115512029221111115,9007,0001.42N31260130312.12.11241265,5006,5001.76N31365140332.12.11351395,1006,0002.18N31470150352.12.11581684,7005,5002.65N31575160372.12.11902054,4005,2003.21N31680170392.12.11902074,1004,8003.77N3178518041332122283,9004,6004.44N3189019043332402653,7004,3005.18N3199520045332592853,4004,0005.99N32010021547332993353,3003,8007.32N32110522549333203603,1003,7008.33N32211024050333604003,0003,5009.77N32412026055334505102,7003,20012.5N32613028058445606652,5002,90017N2300 seriesN23084090331.51.582.5887,0008,2000.932N230945100361.51.5991046,3007,4001.24N23105011040221211315,7006,7001.67N23115512043221481625,2006,1002.13N231260130462.12.11691884,8005,7002.66N231365140482.12.11882124,4005,2003.2N231470150512.12.12232624,1004,8003.9N231575160552.12.12583003,8004,5004.77N231680170582.12.12743303,6004,2005.67N23178518060333153803,4004,0006.57N23189019064333253953,2003,8007.79N23199520067333704603,0003,5009.02           N232010021573334105052,9003,40011.5N232211024080336057902,6003,10016.8N232412026086337109202,4002,80021.1N232613028093448401,1302,2002,60026.4           NJ 1000 seriesNJ10052547120.60.315.114.116,00019,0000.092NJ100630551310.619.719.614,00016,0000.13NJ100735621410.622.623.212,00015,0000.179NJ100840681510.627.32911,00013,0000.22NJ100945751610.631349,90012,0000.28NJ101050801610.632368,90011,0000.295NJ10115590181.1137.5448,2009,7000.442NJ10126095181.114048.57,5008,8000.474NJ101365100181.1141517,0008,2000.485NJ101470110201.1158.570.56,5007,6000.699NJ101575115201.116074.56,1007,1000.738NJ101680125221.1172.590.55,7006,7000.98NJ101785130221.1174.595.55,4006,3001.03NJ101890140241.51.1881145,1005,9001.33NJ101995145241.51.190.51204,8005
