Application: Production facilities, instrumentation industry, control valve manufacturer, power station 8. Disc spring stacks are under hydraulic preload in the open position in quick-action valves. After a failure, the hydraulic pressure drops and releases the spring stack, hence closing the valve. This application mainly uses ball bearing centered stacks. In addition, the spring stack has a self-adjusting function by countering the set-loss of gaskets. This conserves overhead costs as it minimizes required maintenance 9. Annual out put: 40, 000, 000PC/year 10. Place of Origin: Yangzhou, China 11. Brand: Sunzo or OEM 12. Delivery time: 10 days. Standard wood box or carton + case.

1. Ball bearing disc spring are available in two different styles. Sloted ball bearing disc spring. Plain ball bearing disc spring. 2. Material: Alloy steel, carbon steel 3. Surface treatment: Phoaphating, oxidize, polishing 4. The specification is available on the table below 5. We can customize disc spring as per customer's requirements. 6. Usage: It is widely used hydraulic parts, pumps, bearing preload, machinery, textile machinery, etc. Ball bearing disc springs are specially designed as preloading springs for use with radial ball bearings. They help maintain positioning accuracy of the bearing with no end play. They also minimize vibration and shaft deflection. Proper preloading will increase bearing rigidly and eliminate excessive running noise. 7. Annual out put: 40, 000, 000PC/year 8. Place of Origin: Yangzhou, China 9. Brand: Sunzo or OEM 10.elivery time: 10 days. Package: standard wood box or carton + case.
