71952c/AC/B High-Speed Angular Contact Ball Bearings 260*360*46mm P6/P5/P4/P2 Used in Machine Tool Spindles High Frequency Motors, Gas Turbines

Angular contact ball bearings have inner and outer ring raceways that are displaced relative to each other in the direction of the bearing axis. This means that these bearings are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads.The axial load carrying capacity of angular contact ball bearings increases as the contact angle increases. The contact angle is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane, along which the combined load is transmitted from one raceway to another, and a line perpendicular to the bearing axis.     The most commonly used designs are:single row angular contact ball bearings.double row angular contact ball bearings.four-point contact ball bearings. production nameAngular contact ball bearing Single row groundbrandAUTO/OEM/SEMRIModel Number71952C/AC/B Dimension260*360*46mmBasic dynamic load rating246 KNBasic static load rating351 KNAttainable speed for grease lubrication3500 1/minAttainable speed for oil-air lubrication5200 1/minRing MaterialGcr15/ Carbon Steel/ Stainless Steel/ Si3N4/ ZrO2Cage Material Steel/ Brass/ Nylon/ CustomPrecisionP6 P5 P4 P2Vibration Clearance C0,C2,C3, or as requested Quality standardISO9001:2000/ SGSQuality Control Process 1.Assembly2.Windage test2.Windage test3.Cleaning4.Rotary test5.Greasing and gland6.Noise inspection7.Appearance inspection8.Rust prevention9.Product packagingApplication low noise machine,automobile,motorcycle,and the general machinery and etc. 718 Series Angular Contact Bearings719 Series Angular Contact BearingsH719 Series Angular Contact Bearings70 Series Angular Contact BearingsH70 Series Angular Contact BearingsB70 Series Angular Contact Bearings72 Series Angular Contact Bearings  Part No.d/mmD/mmB/mmLoad Rating(KN)Limited  Speed(r/min)Load Rating(KN)Limited  Speed(r/min)Cr/KNCor/KNGrease Oil Cr/KNCor/KNGrease Oil 718 serie   α=15°(C)α=25°(AC)71800101951.81.1750001200001.71.170000110000718011221521.4700001100001.91.3630009500071802152452.21.860000900002.11.7530008000071803172652.31.953000800002.11.8500007500071804203273.93.445000670003.73.2400006000071805253774.24.138000560003.93.9340005000071806304274.44.832000480004.14.5280004300071807354774.65.526000400004.35.224000380007181575951014.221.7120001900013.320.5110001800071816801001014.523.1110001800013.621.895001600071817851101321.532.2100001700020.230.590001500071818901151321.733.595001600020.431.685001400071819951201321.934.790001500020.632.8850014000718201001251322.53785001400021.234.9800013000718211051301322.738.385001400021.336.1800013000718221101401631.851.680001300029.948.7750012000718241201501633.156.970001100031.153.7670010000718261301651838.767.667001000036.363.860009000718281401751844.879.2600090004274.756008500718301501902051.292560085004886.850007500718321602002052.497.75000750049.292.248007000718341702152266.5123.44800700062.4116.543006300718361802252283.8151.64800700078.61434300630071838190240241001794500670094.4169.2400060007184020025024102.5189.34300630096.2178.6380056007184422027024106.4209.33800560099.8197.434005000718482403002814527734005000136261300045007185226032028148.8299.331004600139.6282.3270041007185628035033182363.828004100170.8343.324003700  Part No.d/mmD/mmB/mmLoad Rating(KN)Limited  Speed(r/min)Load Rating(KN)Limited  Speed(r/min)Cr/KNCor/KNGrease Oil Cr/KNCor/KNGrease Oil 719 serie   α=15°(C)α=25°(AC)719073555101110.9260004000010.410.32000034000H719073555107.75.436000530007.45.13000045000H71907/HQ13555107.75.440000600007.45.13400050000719084062121414.2200003400013.313.51800030000H719084062129.8730000450009.36.62600040000H71908/HQ14062129.8734000500009.36.628000430007190945681214.716.1180003000013.915.21700028000H7190945681210.37.726000400009.77.32200036000H71909/HQ145681210.37.728000430009.77.32600040000719105072121921.2170002800017.920.11500024000H71910 721213.210.2220003600012.59.51900032000H71910/HQ150721213.210.2260004000012.59.522000360007191155801323.727.4150002400022.4261400022000H7191155801316.212.5190003200015.211.81600026000H71911/HQ155801316.212.5220003600015.211.822000360007191260851324.830.3140002200023.328.71300020000H7191260851316.513.8180003000015.813.21500024000H71912/HQ160851316.513.8190003200015.813.220000340007191365901325.131.9130002000023.630.21200019000H7191365901316.814.5170002800016.213.81500024000H71913/HQ165901316.814.5190003200016.213.8170002800071914701001634.543.4120001900032.641.21100018000H71914701001620.817.8160002600019.816.81300020000H71914/HQ1701001620.817.8190003200019.816.817000280007191575105162545.611000180003343.29500016000H71915751051621.819.2150002400020.518.21300020000H71915/HQ1751051621.819.2170002800020.518.2150002400071916801101635.547.8100001700033.545.3900015000H71916801101622.520.8140002200021.219.51200019000H71916/HQ1801101622.520.8160002600021.219.5140002400071917 1201846.561.995001600043.858.6850014000H71917851201826.224.2130002000024.822.81100018000H71917/HQ1851201826.224.2150002400024.822.8
