Disc Springs for Hydraulic Seals and Mechanical Compensation
Disc springs combine a simple shape with flexible engineering possibilities. Commonly associated with Belleville washers, these components are ideal for applications requiring high stiffness, compact design, and controlled axial force.
Keywords: disc spring for hydraulic seals, disc spring, disc spring manufacturer, disc spring supplier, Belleville washer, custom disc spring, high load disc spring, precision disc spring, disc spring for axial preload, disc spring applications
How Disc Springs Work
During compression, the cone height changes and the component stores elastic energy. The resulting axial force can be utilized for preload, compensation, actuation, buffering, or mechanical energy storage. The load-deflection relationship is not purely linear, requiring engineers to define actual working points rather than selecting springs by diameter alone.
Load, Deflection and Preload Specifications
Proper specification should identify:
  • Free height and installed height
  • Required force and working deflection
  • Maximum deformation limits
  • Cycle requirements
  • Available installation space
The selected working point should remain within the intended elastic range and be verified against the complete load path and mating components.
Stacking Configurations
Disc springs offer flexible stacking options:
  • Parallel stacking: Increases load capacity
  • Series stacking: Increases available deflection
  • Mixed stacks: Tune the load-deflection curve for specific requirements
Material Selection Guide
SUNZO offers various materials to suit different application requirements:
Material Application Benefits
1074, 65Mn Spring Steel General spring applications
60Si2MnA Enhanced fatigue resistance
SUS304, SUS316 Corrosion-resistant environments
Inconel 718, Inconel X-750 High-temperature applications
Manufacturing Precision
SUNZO emphasizes precision manufacturing with dimensional verification and load-deflection validation. Consistent thickness, diameter, and cone geometry are critical as dimensional variations directly influence working force. For precision mechanisms, required tolerances should be defined alongside load and installed height specifications.
Surface Treatment Options
Available surface treatments include blackening, phosphating, Dacromet, zinc plating, mechanical zinc plating, and PTFE coating. Selection should consider corrosion exposure, friction requirements, temperature conditions, coating thickness, and compatibility with mating components.
Application Considerations
Disc springs are commonly used in structural fastening and flange connections where they provide axial preload, compensate for dimensional changes, absorb mechanical energy, or act as compact elastic actuators. Final configurations should be evaluated as part of the complete assembly, including seat design, load path, travel requirements, and operating environment.
Customization for OEM Projects
Custom disc springs can address non-standard requirements including inner/outer diameters, thickness, cone height, material selection, plate count, and stacking configuration. For OEM projects, providing drawings, samples, or clear application specifications enables comprehensive evaluation of geometry and performance.
Technical Inquiry Requirements
For efficient technical evaluation, include:
  • Inner and outer diameters
  • Thickness and free height
  • Target load and working deflection
  • Cycle requirements and temperature range
  • Material preference and surface treatment
  • Quantity requirements
Mating-part drawings or samples are particularly helpful when replacing existing components.
Frequently Asked Questions
Is a disc spring the same as a Belleville washer?
The terms are commonly used for the same basic conical spring component.
Can disc springs be customized?
Yes, dimensions, materials and configurations can be evaluated for custom requirements.
Can stacking increase load or deflection?
Yes, appropriate parallel or series arrangements change the load-deflection behavior.
How should material be selected?
Consider load, temperature, corrosion, fatigue and the complete service environment.
Jiangsu Sunzo Support: Jiangsu Sunzo Elastic Technology Co., Ltd. develops standard and customized elastic-component solutions for industrial customers. For disc spring projects, Sunzo can evaluate drawings, samples and application requirements, then consider material, geometry, stacking configuration and surface treatment as one integrated specification.
Disc springs represent compact, configurable elastic components ideal for applications requiring axial force, preload, compensation, or shock absorption. By combining suitable geometry, material, surface treatment, and stacking configurations, engineers can develop optimized solutions for structural fastening and flange connections.
