718, 719,70, 72 series single row angular contact ball bearing

A new generation of precision angular contact ball bearings have been developed by ZYS for the machine tool spindle. Comparing with general precision bearings, angular contact bearings are greatly improved in terms of rotation accuracy, limit speed, carrying capacity and reliability; and the size range is also wider. ZYS is able to produce 718 series, 719 series, 70 series and 72 series high speed bearings for machine tool, motor, spindle, power tool and can also develop new products for special application conditions according to customers' needs and provide services for customers.
