Auto Part thrust Ball Bearing, roller bearing, insert/pillow block bearing, wheel Hub Bearing, needle/spherical/cylindrical/Taper Roller Bearing slewing bearing  Product Description ZYS® High precision angular contact ball bearing  Four series: 70,718,719,72Bearing inner diameter: Ф5-Ф460mmTwo kinds of contact angle:  15°(C) and 25°(AC)Performance characteristics of ZYS spindle bearing: Ultra high speed, high stiffness, high carrying capacity, good running performance, easy mounting of universally matchable bearings, suitable for oil and gas lubrication or injection lubrication.Applications of ZYS spindle bearing: ZYS super high speed single row angular contact ball bearings might be used in the fields of machine tools, textiles, automobiles, railways, metallurgy, chemicals, electronics, Industrial pumps, Compressors, Material Handling, Electric motors.Product features of ZYS angular contact ball bearing:1. High-quality bearing materials: ZYS adopts ultra-clean steel, high purity high-carbon chromium bearing steel GCr15 from a well-known domestic manufacturer, which can extend the life of the bearing by 80%.2. High quality bearing rolling elements: The bearing balls provided by ZYS have good product performance to ensure the optimal bearing configuration and smooth operation at high speed and quiet. ZYS has a complete process production line, from powder ultrasonic pre-dispersion, mixture mixing, spray drying granulation, near-net-size molding, cold isostatic pressing, GPS-HIP combined sintering process, high-precision grinding and processing, total quality inspection to packaging. ZYS has a comprehensive quality control system, quality identification of raw materials and auxiliary materials, quality control of mixed materials, quality control of pressing and sintering, and quality control of finished products.3. More suitable bearing cage: ZYS mostly adopts bakelite cage, which can more effectively reduce the friction between metal and bearing balls and extend the life of the bearing. ZYS can also choose more suitable bearing cage materials according to customer requirements and bearing applications.4. Advanced lubrication technology: ZYS uses high performance grease and advanced lubrication technology to extend bearing life and improve bearing performance.5. Ultra finished raceways: ZYS uses special honing to minimize noise, improve lubricant dispersion and increase bearing life.6. Contact angle: ZYS ultra high speed precision bearings usually use 15°and 25° contact angles.7. Accuracy grade: ZYS can offer the high precision angular contact ball bearings with P2, P4A, P4 grade.H70/H719 series Super high speed angular contact ball bearingPrincipal dimensionsα= 15°α= 25°ZYS Bearing Designations Basic load ratingsLimiting speedBasic load ratingsLimiting speed dDBrsminrIsminCrCorGreaseOilCrCorGreaseOil mm≈KNr/min     102260.300.102.10.9850001400002.00.975000120000H71900102260.300.102.10.9950001600002.00.985000140000H71900/HQ1102680.300.153.41.5800001300003.31.467000110000H7000102680.300.153.41.5900001500003.31.480000130000H7000/HQ1122460.300.102.21.1800001300002.11.170000110000H71901122460.300.102.21.1900001500002.11.180000130000H71901/HQ1122880.300.153.81.7700001100003.61.66000090000H7001122880.300.153.81.7800001300003.61.670000110000H7001/HQ1152870.300.103.21.7700001100003.11.66000090000H71902152870.300.103.21.7800001300003.11.670000110000H71902/HQ1153290.300.154.42.2670001000004.22.15600085000H7002153290.300.154.42.2750001200004.22.167000100000H7002/HQ1173070.300.103.31.8670001000003.21.75600085000H71903173070.300.103.31.8750001200003.21.76300095000H71903/HQ11735100.300.155.22.556000850005.02.45000075000H70031735100.300.155.22.563000950005.02.46000090000H7003/HQ1203790.300.155.02.953000800004.82.74500067000H71904203790.300.155.02.963000950004.82.75300080000H71904/HQ12042120.600.157.43.950000750007.03.84300063000H70042042120.600.157.43.960000900007.03.84800070000H7004/HQ1254290.300.155.23.448000700004.93.34000060000H71905254290.300.155.23.453000800004.93.34500067000H71905/HQ12547120.600.158.44.843000630008.04.63600053000H70052547120.600.158.44.848000700008.04.64300063000H7005/HQ1304790.300.155.83.843000630005.43.63600053000H71906304790.300.155.83.848000700005.43.64000060000H71906/HQ13055131.000.309.56.238000560009.05.93400050000H70063055131.000.309.56.245000670009.05.93800056000H7006/HQ13555100.600.157.75.436000530007.45.13000045000H719073555100.600.157.75.440000600007.45.13400050000H71907/HQ13562141.000.3011.27.9340005000010.77.53000045000H70073562141.000.3011.27.9380005600010.77.53400050000H7007/HQ14062120.600.159.87.030000450009.36.62600040000H719084062120.600.159.87.034000500009.36.62800043000H71908/HQ14068151.000.3012.59.1280004300011.18.62400038000H70084068151.000.3012.59.1340005000011.18.62800043000H7008/HQ14568120.600.1510.37.726000400009.77.32200036000H719094568120.600.1510.37.728000430009.77.32600040000H71909/HQ14575161.000.3013.110.2240003800012.59.72200036000H70094575161.000.3013.110.228000430001
