Description: NA4900 RNA4900 NA4901 NA4902 NA4903 NA4904 NA49/22 NA4905 NA4906 needle bearing Desicrption Needle roller bearing (solid ring needle roller bearing) The solid ring needle roller bearing is composed of a ring and a needle roller group with a cage. It has smaller volume and higher carrying capacity. Therefore, this kind of bearing can meet the requirements of light weight, small space and large transmission power. Depending on the application, bearings with or without an inner ring are availableInner ring needle roller bearings RNA, NK type Needle roller bearings without inner ring are suitable for components with limited radial dimensions. Because there is no inner ring, the journal surface that matches it directly serves as the rolling surface. It is required that the surface hardness is not lower than HRC6O, and the surface roughness ra value is not more than 0.63um. This kind of bearing does not limit the axial displacement of the shaft or the shell, and the limit speed is high. There are inner ring needle roller bearings NA, NKI type This kind of solid ferrule needle roller bearing has no ribs on the inner ring, so the inner ring, the outer ring, the full set of needle rollers and the cage can be installed separately without restricting the axial displacement of the shaft or the housing. Because the cage separates the needle rollers and reduces friction, it can be used in components with higher rotational speeds. Needle roller bearings without inner ring with cageNA and NKI type bearings without inner ring are RNA and NK type needle roller bearings.This kind of bearing has no inner ring and is suitable for the support structure with limited radial installation size, and the journal matched with the bearing directly serves as the rolling surface. As the shaft of the raceway surface, the hardware must be hardened and ground, and only when it is processed to the appropriate size and shape accuracy, the complete set of needle roller bearings can achieve high life and running accuracy. At the same time, since there is no inner ring, the diameter of the shaft can also be appropriately increased, thereby increasing the rigidity.Sealed needle roller bearings with or without inner ringNeedle roller bearings sealed on one or both sides can effectively prevent the intrusion of dirt, and the bearing has been filled with an appropriate amount of lithium-based grease. The inner ring of this type of bearing is wider than the outer ring, which enables the bearing to ensure a good seal even when the shaft has a slight displacement relative to the bearing housing to avoid contamination of the bearing. The inner ring of the bearing also has lubricating oil holes, which can be supplemented by the outer ring or the inner ring according to the needs of the configuration.We offer different types RNA4900 14*22*13 No inner ring solid ferrule needle roller bearingNA4900 10*22*13 Needle roller bearing with inner ring solid ringRNA4900RS 14*22*13 No inner ring single seal solid ring needle roller bearingNA4900RS 10*22*14 Solid ring needle roller bearing with inner ring sealRNA4900.2RS 14*22*13 No inner ring double seal solid ring needle roller bearingNA4900.2RS 10*22*14 Solid ring needle roller bearing with inner ring sealIR101413 IR101414 OH inner ring available from stockApplicationHeavy industry machine tool parts matchinggearboxtransfer caseengineSteering and Braking SystemAxle support endoutboard engineelectrical toolscopierprinting pressfax machineAll kinds of machineryStock bearing model number ShaftDesignationMassDimensionsBasic Load RatingsLimitingDiameter dFDBr Cr CorSpeed DynamicStatic mm g min.kNkNrpm10NA 490023.0 101422130.3 8.6 9.2 2000012NA 490126.0 121624130.3 9.6 10.9 1700015NA 490234.0 152028130.3 10.8 13.9 1400017NA 490337.0 172230130.3 11.6 15.4 1200020NA 490475.2 202537170.3 20.9 25.1 1100022NA 49/2280.0 222839170.3 23.1 29.1 950025NA 490588.0 253042170.3 23.5 30.7 950028NA 49/2897.7 283245170.3 24.8 33.2 850030NA 4906101.0 303547170.3 25.5 35.4 800032NA 49/32158.0 324052200.6 31.6 46.8 700035NA 4907170.0 354255200.6 32.5 51.0 700040NA 4908230.0 404862220.6 43.4 66.1 600045NA 4909271.0 455268220.6 45.8 72.9 550050NA 4910274.0 505872220.6 48.0 80.0 500055NA 4911393.0 556380251.0 63.5 110.1 470060NA 4912426.0 606885251.0 66.4 119.6 430065NA 4913456.0 657290251.0 67.6 124.6 410070NA 4914728.0 7080100301.0 91.8 169.9 380075NA 4915775.0 7585105301.0 95.8 183.3 360080NA 4916878.0 8090110301.0 97.3 190.4 340085NA 49171250.0 85100120351.1 119.0 255.2 310090NA 49181312.0 90105125351.1 120.6 263.7 300095NA 49191371.0 95110130351.1 124.7 279.7 2800100NA 49201900.0 100115140401.1 151.4 313.9 2900110NA 49222070.0 110125150401.1 152.8 326.1 2600120NA 49242860.0 120135165451.1 208.0 425.3 2300130NA 49263014.0 130150180501.5 233.0 508.9 2000140NA 49282860.0 140160190501.5 241.3 543.9 1700150NA 49303000150170210601.5 241.3 543.9 1700We also offer other model as belowK series needle roller bearings.
