Ex-stock standard sizes of extension springs in music wire and stainless steel are a mainstay of many industrial products, so it is good news that Lee Spring has introduced 121 new sizes including shorter and longer designs, plus new 16.5mm (0.650 inches) outer diameter families.
With new sizes available in both music wire and stainless steel, this means 242 new catalogued springs available for use in applications such as automotive interiors and exteriors, garage door assemblies, vise-grip pliers, carburettors, trampolines, washing devices, farm machinery, toys, as well as thousands of other uses. Lee extension springs come in a wide array of sizes, suitable for small medical devices to off-road machinery brake springs.
Lee Spring standard stock extension springs have end loops positioned in random orientation - while loops in-line can be provided as custom parts. Loops are formed in either English or Continental style.
Speciality extension spring ends include threaded inserts, extended twist loops, crossover centre loops, hooks, expanded eyes, reduced eyes, rectangular ends and teardrop-shaped ends, which can all be produced to vary in distance from the spring body. At the design stage of Custom Extension Springs, the length of the hooks at each end of the spring can be adjusted in order to precisely obtain the required spring load at any extended position.
