Compression Spring Types:
Compression springs from a manufacturer come in a variety of types including:
Conical, Barrel, Hourglass and Cylindrical shapes.
Wire Selection: round, square or special-section, round being the most adaptable.
Compression Spring Mandatory Specification: the functional design characteristics.
Compression Spring Secondary Specification: which is useful for reference and been considered as advisory data.
Dimensional Limits: governed by the pitch allotted with regard to allowable solid height and outer and inner diameters.
determined by the dimensional limits together with the load and deflection requirements. Our compression springs are stress-relieved to remove residual bending stresses produced by the coiling operation.
Compression Spring Stress Levels
A compression spring can be compressed into solid without a permanent set, so that an extra operation for removing the set is not needed. These springs are designed with torsional stress levels when compressed into solid that do not exceed above 40 percent of the minimum tensile strength of the material.
A compression spring can be compressed into solid without further permanent set after the set is initially removed. These may be pre-set by the spring manufacturer as an added operation, or they may be pre-set later by the user prior to or during the assembly operation. These are springs designed with torsional stress levels when compressed to solid that do not exceed 60 percent of the minimum tensile strength of the material.
Springs, which cannot be compressed into solid without some further permanent set-taking place is because set cannot be completely removed in advance. These springs involve torsional stress levels, which exceed 60 percent of the minimum tensile strength of the material. The spring manufacturer usually advise the user of the maximum allowable spring deflection without set whenever springs are specified in this category.
