Spring specifications and models mainly include the following aspects:
Wire Diameter: Indicates the diameter of the steel wire used to make the spring, usually in millimeters (mm). For example, a spring with a wire diameter of 20mm means that its wire diameter is 20mm.
Outer Diameter: The maximum outer diameter of the spring, which is also the maximum diameter of the spring cross section. For example, a spring with an outer diameter of 120mm means that its maximum outer diameter is 120mm.
Inner Diameter: The minimum outer diameter of the spring, that is, the diameter of the space inside the spring. For example, a spring with an inner diameter of 60mm means that its inner diameter is 60mm.
Free Length: The length of the spring when it is not subjected to external force. For example, a spring with a free length of 60mm means that its length when it is not subjected to force is 60mm.
Total Coils: The total number of coils of the spring, including the number of effective coils and the number of support coils. For example, a spring with a total number of turns of 15N means that its total number of turns is 15.
Material: Springs are usually made of elastic materials, and common materials include spring steel, stainless steel, etc. For example, stainless steel 316 springs have good corrosion resistance.
Examples of specifications and models of different types of springs:
Compression springs: Common models such as C040, C065, C085, etc., with a wire diameter range of 0.2mm~10mm, a diameter range of 3.2mm~50mm, and a length range of 6.5mm~305mm.
Stretch springs: Common models such as D035, D055, D085, etc., with a wire diameter range of 0.2mm~5mm, a diameter range of 0.2mm~35mm, and a length range of 2mm~1000mm.
Torsion spring: Common models include T010, T015, T020, etc., with wire diameters ranging from 0.1mm to 10mm, diameters ranging from 0.1mm to 50mm, and lengths ranging from 0.5mm to 1200mm.
These specifications can help users choose the right spring according to their specific needs to ensure that it can work properly in a specific application.
