Answer
Nested wave springs must be installed with their waves perfectly 'in phase' to act as a parallel spring. If the turns are misaligned, they may partially act in series or cause interference, leading to an incorrect spring rate. Most manufacturers provide nested springs pre-aligned, but if manual assembly is required, the technician must index the starting point of each turn. In high-vibration environments, it is recommended to use an internal pilot or an external sleeve to maintain this alignment during the lifecycle, preventing the turns from shifting tangentially and changing the spring's characteristic response.
