Extension springs, also known as tension springs, are designed to store energy and offer resistance to a pulling force. The ends typically have machined, crossover, side or extended hooks/loops, but can also be manufactured with double-loops or other various end configurations. Generally, extension springs have a constant-diameter body. However, it is not uncommon for a customer to require a conical, barrel or hourglass-shaped design.
Peninsula Spring has decades of engineering and manufacturing experience to aid in the design of all types of extension springs. We can help design a spring to meet the required force and deflection (travel) while staying within the required space constraints. We can estimate both hook and coil-body fatigue life and can use various methods to increase spring life.
