A disc spring, or Belleville washer, is a conical-shaped elastic component designed to deliver high stiffness and efficient shock absorption. Unlike traditional springs, it can bear large loads with minimal axial deformation, making it suitable for occasions with limited space. Key characteristics of SUNZO Disc Spring include variable stiffness, broad non-linearity, and excellent durability. Its industrial applications span hydraulic energy storage systems, precision machinery, aerospace, and automotive industries, where it serves as an energy storage element or shock absorber. SUNZO provides professional disc spring solutions, including standard products and non-standard customization, to fit diverse working scenarios.
