The double-groove disc spring is a high-performance special disc spring with radial grooves on both internal and external radial sides, featuring a unique structural design that optimizes load distribution and elastic performance. It delivers excellent stiffness, stable buffer and shock absorption capacity, and can bear heavy loads with small axial deformation, suitable for various industrial precision equipment. Made from premium materials like 65Mn, SUS304 and 50CrVA, it supports multiple surface treatments including phosphating and dacromet for enhanced corrosion resistance. This elastic component is widely used in mechanical equipment with strict structural and performance requirements, providing reliable axial preload and energy storage.
