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
