Belleville springs (also known as disc springs) are key elastic preloading components for sealing in industrial applications. Featuring compact size, high load capacity, short stroke, reliable performance and flexible assembly options, they make up for the performance limitations of conventional coil springs. By adopting single-piece, stacked or nested configurations, disc springs can meet diverse load and stroke requirements. They deliver multiple functions including vibration damping, pressure compensation, anti-loosening and clearance adjustment, and are widely deployed in precision and heavy-duty industrial equipment.
Material selection is critical to the fatigue life, temperature resistance, corrosion resistance and anti-relaxation performance of disc springs. Proper material choice lays a solid foundation for long-term stable equipment operation. Mascot Technology has long been engaged in the R&D and manufacturing of disc springs. Supported by mature production processes and a complete material portfolio, we supply high-quality disc springs tailored to complex working conditions for various industries.
Compared with conventional elastic components, disc springs possess remarkable advantages for industrial use. Their compact structure enables high load bearing within limited installation space. Flexible assembly schemes cater to heavy-load or long-stroke demands. With inherent damping effects, they perform well in impact absorption and vibration suppression. When manufactured from premium materials, disc springs feature good resistance to stress relaxation and fatigue. Capable of sustaining constant pressure over extended periods, they adapt to diverse challenging conditions ranging from normal temperature, alternating high and low temperatures to corrosion and high pressure, demonstrating better durability than ordinary springs.
Drawing on years of manufacturing experience, Mascot Technology has developed a comprehensive material system covering general service, anti-corrosion and high-temperature extreme working scenarios to satisfy differentiated industrial demands.
60Si2MnA silicon-manganese spring steel serves as the standard option for general industrial applications. Operating within -40℃ to 250℃, it delivers balanced elasticity and strong impact resistance with favorable cost performance and stable mass production. Widely applied in machine tools, molds, general hydraulic systems, standard machinery and conventional rail transit equipment, it is a preferred material for ordinary civilian working conditions.
For heavy-duty, high-frequency cyclic and moderately high-temperature harsh operating conditions, 50CrVA chromium-vanadium spring steel is a recommended choice. It withstands temperatures up to 300℃. Compared with silicon-manganese spring steel, it achieves notable improvements in resistance to high-temperature relaxation, high stress and fatigue, maintaining stable pressure bearing without obvious deformation over long service hours. It is commonly used in automotive braking systems, heavy-duty hydraulic equipment, preloading structures of industrial valves, construction machinery and other high-load scenarios.
For humid, outdoor and corrosive environments, Mascot Technology provides a full range of stainless steel disc springs. Grade 304 stainless steel fits lightly corrosive and damp open-air environments. It features clean anti-rust properties and requires minimal maintenance without complicated surface treatment. Grade 316 stainless steel contains molybdenum, offering outstanding resistance to salt spray, seawater, weak acids and alkalis. It is developed for marine vessels, coastal facilities, wet chemical working conditions, medical equipment and other heavily corrosive environments.
17-7PH precipitation hardening stainless steel combines high strength, excellent fatigue resistance, anti-relaxation performance and moderate temperature resistance. Its mechanical properties outperform conventional spring steel and ordinary stainless steel, making it a favorable material for aerospace equipment, military devices, high-end precision hydraulic valves and equipment under intensive cyclic heavy loads.
Disc springs manufactured by Mascot Technology serve numerous sectors including hydraulic fluid control, precision molds, automotive & rail transit, aerospace & defense, petrochemical energy and marine engineering. Adhering to the selection principle of “condition adaptability, performance priority and cost rationality”, we match suitable materials and processes according to operating temperature, corrosive atmosphere, load frequency and service life requirements, helping avoid common failures such as relaxation, fracture and rust of disc springs from the source.
As industrial equipment evolves toward higher precision, better durability, adaptability to extreme environments and compact integration, customized high-grade, miniature precision and modular standardized disc springs represent an important trend in the industry. Moving forward, Mascot Technology will continue advancing technological innovation, optimizing material formulation and production processes. We provide high-quality, well-adapted and durable disc springs to support stable operation of equipment across all industries.
