A cantilever U spring energizer, also known as a U spring or meander U spring, is a formed metal spring used inside spring-energized sealing systems. Its U-shaped profile flexes under compression to provide the spring force needed to maintain contact between the seal jacket and the mating surface.
The spring’s load characteristics are influenced by its profile geometry, material, strip thickness, and installed deflection. Compared with a V spring of the same size and material, Handa’s U spring design can provide higher spring load and a more stable load response over a wider deflection range, depending on the selected profile and working range.
Handa Spring manufactures U spring energizers for customers developing or producing sealing components. We support profile selection, dimensional customization, material review, and spring-load requirements based on drawings, samples, or application details.
