In custom compression spring design, the space allotted governs the dimensional limits of a spring with regard to allowable solid height and outside and inside diameters. These dimensional limits, together with the load and deflection requirements, determine the stress level and mechanical property requirements of the material. It is extremely important to consider carefully the space allotted to ensure that the spring will function properly, thereby avoiding costly design changes.
The illustration of spring dimensions below is recommended as a guide in specifying heavy duty compression springs. The functional characteristics of spring design should be given as mandatory specifications. Secondary characteristics, which may well be useful for reference, should be identified as advisory data. This practice controls the essential requirements while providing as much design flexibility as possible to the spring manufacturer in meeting these requirements.
