In high-precision mechanical systems, disc springs (also known as Belleville springs) play a crucial role in absorbing force, maintaining preload, and providing compact, reliable elastic support. Raleigh Spring Technology Co., Ltd., a leading innovator in spring technology, specializes in the R&D, manufacturing, and customization of high‑precision disc springs. With advanced production capability and rigorous quality control, Raleigh Spring provides durable, high‑stiffness, and fatigue‑resistant disc springs tailored for demanding industrial applications. 

Below, we explore the top applications of disc springs in automotive, machinery, and engineering — and illustrate how Raleigh Spring’s expertise supports these critical use cases.

Automotive Applications: Reliable Preload and Shock Absorption

In the automotive industry, disc springs are widely used to manage clutch preload, suspension force balancing, and brake mechanisms. Their compact, high-load design allows engineers to maintain precise axial force in constrained spaces — resulting in more consistent clutch engagement and improved vehicle responsiveness.

Raleigh Spring’s heat-resistant disc springs and standard DIN‑compliant disc springs offer high stiffness and long fatigue life, ensuring that safety-critical components maintain stable performance even under vibration, thermal cycling, and repeated loading. 

Heavy Machinery and Industrial Equipment

Machinery such as press machines, stamping dies, and metal-forming equipment rely on robust spring systems to absorb shock and maintain alignment. Disc springs are particularly effective in these scenarios: their nonlinear stiffness provides a strong force with minimal deflection, protecting machinery from overload and reducing maintenance costs.

Raleigh Spring’s capability to stack disc springs in parallel, in series, or in a hybrid configuration enables designers to fine-tune force-deflection curves for custom applications. Their high-carbon steel and alloy-steel disc springs, treated with durable surface finishes, deliver long-term reliability under extreme mechanical stress. 

Engineering & Structural Applications

In civil engineering and infrastructure applications — such as bridge bearings, seismic damping systems, and wind turbines — disc springs provide compact, high‑capacity elastic support. Their ability to sustain large forces while undergoing small deformations makes them ideal for vibration isolation, energy absorption, and preload control.

Raleigh Spring’s disc springs — available in special materials and custom sizes (from small Ø8 mm units to large Ø200 mm variants) — are manufactured with precision to fulfill the rigorous demands of structural and infrastructure engineering.

Valve and Fluid Control Systems

Disc springs also find use in valve mechanisms and high-pressure fluid systems. Valves equipped with Belleville springs benefit from precise force maintenance, ensuring reliable sealing and steady operation over long service cycles.

Raleigh Spring’s valve disc springs are engineered for high fatigue performance, corrosion resistance, and dimensional accuracy. These springs are especially valuable in applications where safety, pressure stability, and long-term reliability are essential. 

High‑Temperature and Corrosion‑Resistant Scenarios

In environments where temperature extremes or corrosive media are a concern — such as aerospace, chemical processing, or power generation — specialized disc springs are required. Raleigh Spring offers heat‑resistant and corrosion‑resistant disc springs, including Inconel® Grade options and stainless steel variants, engineered to maintain their spring characteristics under demanding conditions. 

Custom or Stacked Spring Solutions for Precision Engineering

Sometimes a single disc spring does not deliver the required force or deflection. In such cases, engineers turn to stacked configurations. Raleigh Spring excels in providing application‑engineered spring assemblies, combining multiple disc springs in parallel, series, or hybrid stacks to realize custom stiffness curves, tailored preload, and better force distribution. 

High‑Torque Disc Spring Application

One of the hallmark products in Raleigh Spring’s catalog is its high‑torque disc spring, used in torque-sensitive systems or preloaded mechanisms where torque stability is critical. These springs deliver stable, high preload with minimal relaxation, ensuring long-term mechanical integrity in rotating or adjustable assemblies.
