Benefits of Nested Springs Nested springs have multiple turns, coiled in parallel to produce higher forces. This type of wave spring is designed to produce very high spring forces compared to standard single-turn springs. Nested springs are used primarily in the automotive, oil & gas, and connector industries. They can be found in a variety of applications, such as seals and valves, and can be used to preload a bearing. Incorporate a Nested wave spring when your application requires more force. Nested wave spring forces increase proportionally with the number of turns in the coil. Compressing a wave spring creates bending, or tensile stresses, which can limit the amount of force the spring can produce without failing or permanently deforming. It is recommended that that the calculated operating stress be less than the minimum tensile strength of the material in static applications and less than 80% of the minimum tensile strength in dynamic applications. Stacking singleturn springs can achieve a higher load while distributing the stresses evenly across the parts. One Nested spring provides the desired load without the complication of stacking multiple parts. Use a nested wave spring when misalignment during installation caused uneven loading. When the desired load requires multiple single-turn springs to be stacked in an assembly, consider a nested spring. The gaps in stacked single-turn springs must be aligned to prevent binding or uneven loading when compressed. Unlike stacks, nested springs are single, continuous filaments of flat wire—which guarantees the multiple layers stay aligned for consistent loading. Consider a nested wave spring when you want production to be simple and cost-effective. Unlike a stack of single-turn springs, which need to be individually installed to guarantee repeatability, nested springs are a single part that can be dropped directly into the housing. This approach simplifies and speeds up installation, saving time and money. Standard Nested Spirawave® springs from Smalley offer a direct part cost savings when compared with stacks of comparable standard single-turn wave springs.

Top 6 Benefits of Nested Springs Choose a nested wave spring when automatic handling is used during assembly. Other types of springs can be deformed by a robotic arm during a pick-and-place process or can tangle when placed in a hopper for vibratory sorting and feeding. This results in lost time because the parts must be sorted and assembled by hand. Nested springs are ideal for automated processes because they have no floating ends and the turns sit tightly together, which prevents tangling. The multiple-turn configuration of the nested wave spring design is also sturdy, perfect for easy pick-and-place...
