ZYS Precision Bearings for Machine Tools
A new generation of super precision angular contact ball bearings have been developed by ZYS for the machine tools. Comparing with general P4 precision bearings, ZYS bearings totally reach and above P4A accuracy, they 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 , 72 series, 73 series and 760/BS series precision angular contact ball bearings and can also develop new products for special application conditions according to customers' needs
Technical features:
- Optimize the raceway curvature radius of the ring for easy installation and improvement of mounting accuracy.
- Speed performance increased by 30%.
- Product size specifications increase.
- Advanced heat treatment processes maximize the dimensional stability and hardness of bearing part and then reduce wear.
- Designed with multiple preload levels to meet speed and rigidity requirements for a variety of applications.
Unique preload option:
- Level A, light preload.
- Level B, medium preload.
- Level C, heavy preload.
