Product Description PRODUCT DETAILS NJ211EM, NJ217EM, NJ314, and NJ315 all belong to the cylindrical roller bearing series. With their unique structural design and excellent performance, they hold an important position in the industrial field. These bearings adopt a structure where rollers come into contact with the raceway lines. Compared to ball bearings, they can withstand greater radial loads and maintain a stable operating state even under high-load conditions. The NJ211EM bearing features an optimized cage structure for precise guidance of the rollers, reducing friction losses during operation. It performs exceptionally well in the main shaft system of machine tools, providing stable support for the rotation of precision lathes and milling machines, ensuring accuracy and efficiency during cutting operations, especially suitable for high-speed cutting environments. The NJ217EM bearing has excellent rigidity in its structure and an easily separable inner ring for convenient installation and maintenance. It is widely used in heavy machinery fields, such as the transmission shafts of mining crushers, and can withstand the huge radial impact forces generated during crushing operations. In the roller support of metallurgical rolling mills, it can adapt to the high-strength working requirements of continuous production. The NJ314 bearing ensures perfect cooperation between the raceways and rollers through high-precision manufacturing processes. It has significant application effects in electrical machinery equipment, whether it is the rotor support of large industrial motors or the transmission system of wind turbines, effectively reducing operating noise and improving the efficiency and lifespan of the motor. The NJ315 bearing undergoes special processing to possess excellent wear resistance and fatigue resistance. It shines in the construction machinery field, such as the transmission boxes and drive axles of loaders and excavators, capable of adapting to the complex working conditions of field operations and maintaining reliable transmission performance even in dusty and vibrating environments. These bearings collectively provide critical support for the normal operation of equipment in industries such as mechanical manufacturing, energy and chemical engineering, and transportation, being important basic components that ensure efficient and stable industrial production.MORE PHOTOS CATALOGUEBearing No.Dimension(mm)Weight(Kg) Model No.dDBN/NJ/NU/NUP/NF202E/ EM1535110.008N/NJ/NU/NUP/NF203E/ EM1740120.009N/NJ/NU/NUP/NF204E/ EM2047140.109N/NJ/NU/NUP/NF205E/ EM2552150.155N/NJ/NU/NUP/NF206E/ EM3062160.24N/NJ/NU/NUP/NF207E/ EM3572170.36N/NJ/NU/NUP/NF208E/ EM4080180.44N/NJ/NU/NUP/NF209E/ EM4585180.53N/NJ/NU/NUP/NF210E/EM5090200.58N/NJ/NU/NUP/NF211E/EM55100210.63N/NJ/NU/NUP/NF212E/EM50110220.95N/NJ/NU/NUP/NF213E/EM65120231.15N/NJ/NU/NUP/NF214E/EM70125241.34N/NJ/NU/NUP/NF215E/EM75130251.72N/NJ/NU/NUP/NF216E/EM80140261.76N/NJ/NU/NUP/NF217E/EM85150282.1N/NJ/NU/NUP/NF218E/EM90160302.63N/NJ/NU/NUP/NF219E/EM95170323.06N/NJ/NU/NUP/NF220E/ EM100180343.45N/NJ/NU/NUP/NF221 E/ EM105190364.4N/NJ/NU/NUP/NF222E/ EM110200385.36N/NJ/NU/NUP/NF224E/ EM120215405.85N/NJ/NU/NUP/NF226E/ EM130230407N/NJ/NU/NUP/NF228E/ EM140250429N/NJ/NU/NUP/NF230E/ EM1502704511.7N/NJ/NU/NUP/NF232E/ EM1602904812N/NJ/NU/NUP/NF234E/ EM1703105218N/NJ/NU/NUP/NF236E/ E1803205219.2N/NJ/NU/NUP/NF238E/ EM1903405521.6N/NJ/NU/NUP/NF240E/ EM2003605828N/NJ/NU/NUP/NF244E/ EM2204006539N/NJ/NU/NUP/NF248E/ EM2404407251N/NJ/NU/NUP/NF252EZ EM2604808070Bearing No.Dimension(mm)Weight(Kg)Model No.dDBN/NJ/NU/NUP/NF303E/EM1747140.1387N/NJ/NU/NUP/NF304E/EM2052150.149N/NJ/NU/NUP/NF305E/EM2562170.28N/NJ/NU/NUP/NF306E/EM3072190.3N/NJ/NU/NUP/NF307E/EM3580210.54N/NJ/NU/NUP/NF308E/EM4090230.71N/NJ/NU/NUP/NF309E/EM45100250.98N/NJ/NU/NUP/NF310E/EM50110271.31N/NJ/NU/NUP/NF311E/EM55120291.7N/NJ/NU/NUP/NF312E/EM60130312.07N/NJ/NU/NUP/NF313E/EM65140332.58N/NJ/NU/NUP/NF314E/EM70150353.04N/NJ/NU/NUP/NF315E/EM75160373.88N/NJ/NU/NUP/NF316E/EM80170394.3N/NJ/NU/NUP/NF317E/EM85180415.25N/NJ/NU/NUP/NF318E/EM90190436.24N/NJ/NU/NUP/NF319E/EM95200457.27N/NJ/NU/NUP/NF320E/EM100215477.8N/NJ/NU/NUP/NF321E/EM1052254911N/NJ/NU/NUP/NF322E/EM1102405012N/NJ/NU/NUP/NF324E/EM1202605514N/NJ/NU/NUP/NF326E/EM1302805818N/NJ/NU/NUP/NF328E/EM1403006220.3N/NJ/NU/NUP/NF330E/EM1503206526N/NJ/NU/NUP/NF332E/EM1603406832N/NJ/NU/NUP/NF334E/EM1703607239N/NJ/NU/NUP/NF336E/EM1803807544N/NJ/NU/NUP/NF338E/EM1904007850N/NJ/NU/NUP/NF340E/EM2004208057LISTModeldDBCrCorLimiting Speed (r/min)Mass(mm)(mm)(mm)(kN)(kN)GreaseOil(kg)NU2021535117.985.51500019000-NU2031740129.1271400018000-NU30317471412.810.813000170000.147NU100420421210.59.213000170000.09NU204E20471425.82412000160000.117NU2204E20471830.83012000160000.149NU3O4E2052152925.511000150000.155NU2304E20522139.237.510000140000.216NU10052547121110.211000150000.1NU205E25521527.526.811000140000.14NU2205E25521832.833.811000140000.168NU305E25621738.535.89000120000.251NU2305E25622453.254.59000120000.355NU10063055131312.89500120000.12NU206E3062163635.58500110000.214NU2206E30622045.5488500110000.268NU306E30721949.248.28000100000.377NU2306E3072277075.58000100000.538NU40630902357.253700090000.73NU100735621419.518.88500110000.16NU207E35721746.548750095000.311NU2207E35722357.563750095000.414NU307E3580216263.2700090000.501NU2307E35803187.598.2700090000.738NU407351002570.868.2600075000.94NU100840681521.222750095000.22NU208E40801851.553700090000.394NU2208E40802367.575.2700090000.507NU308E40902376.877.8630080000.68NU2308E409033105118630080000.974NU408401102790.589.8560070001.25NU100945751623.223.8650085000.26NU209E45851958.563.8630080000.45NU2209E4585237182630080000.55NU309E45100259398560070000.93NU2309E4510036130152560070001.34NU4004512029102100500063001.8NU10105080162527.563008000-NU210E50902061.269.2600075000.505NU2210E50902374.288.8600075000.59NU310E5011027105112530067001.2NU2310E5011040155185530067001.79NU4105013031120120480060002.3NU101155901835.840560070000.45NU211E551002180.295.5530067000.68NU2211E551002594.8118530067000.81NU311E5512029128138480060001.53NU2311E5512043190228480060002.28NU4115514033128132430053002.8NU101260951838.545530067000.48NU212E601102289.8102500063000.86NU2212E6011028122152500063001.12NU312E6013031142155450056001.87NU2312E6013046212260450056002.81NU4126015035155162400050003.4COMPANY INTRODUCTIONPRODUCTION PROCEDURERELATED PRODUCTSFUNCTIONOUR ADVANTANGE
