Detached Leg Spring is also known as: Detached Leg Spring, Fishback Spring, Fish Back Spring.
Large heavy load geometry that provides a heavy load over a wide deflection range and is used in dynamic and static applications. The Detached Leg Spring is available in five standard sizes in the 301 SS Material and available in four standards in the Elgiloy material. This spring is produced in continuous lengths. Free height diamention range from .386″ to 1.120′.
Materials available include:
Stainless Steels 301 , 302 , 304 , 316 , 17/7PH
Exotic Alloys Inconel (grades 600, 718, X-750) Monel (grade 400) Elgiloy/Phynox to AMS5833. Also available compliant to NACE MR0175. Hastelloy (grades C22, C276, C2000) VictrexTM PEEK

Applications
While not explicitly stated in the provided information, detached leg springs are likely used in applications requiring high load-carrying capacity and resistance to deformation over a wide range of motion. Common uses might include:
Sealing applications in industrial equipment
Heavy-duty machinery components
Applications requiring vibration dampening
Manufacturing Process
Each spring is manufactured using standard tooling
Minor variations to dimensions can be made with minor adjustments to tooling
More significant changes may require inquiry about non-standard cross-sections.
