Professional Manufacturer of Large Extension Springs in China
Large extension springs, also known as heavy-duty extension springs, are characterized by their robust wire diameter, which necessitates corresponding larger dimensions in proportion to the selected wire diameter. The spring index, which relates to the relationship between the wire diameter and outside diameter, plays a crucial role in determining the strength of the spring. A tighter spring index results in greater strength but also increases stress and manufacturing complexity. To ensure high elasticity, it is important to avoid an excessively tight index.
For a wide selection of large springs, consider China Custom Spring. Our stock extension spring catalog features a diverse range of designs with wire diameters ranging from 0.007″ to 0.375″. The materials commonly used for large extension springs include Music Wire ASTM A228, Hard Drawn ASTM A227, Oil Tempered MB A229, and Stainless Steel 302 A313.
Utilize our user-friendly online tool, Spring Finder, to quickly locate your large springs. Simply input key dimensions such as outer diameter, length inside hooks, wire diameter, initial tension, load, deflection, and material type into the search parameters. By setting tolerances based on your design requirements, such as specifying a minimum and maximum outer diameter for a given hole size, you can efficiently filter through springs that meet your criteria.
