Loads at length define the force a tension spring produces when stretched to a specific length. Unlike compression springs, tension springs are designed to work in extension and include an initial preload that must be overcome before any movement occurs. Loads at length provide a clear and practical way to specify real working performance. What Are Loads at Length A load at length is the force measured when a tension spring is extended to a defined overall length. For [...]

Torsion springs store energy by twisting and produce torque in response to rotational movement. The ends of a torsion spring, often called legs, are critical to how the spring mounts and how torque is transferred into the assembly. The shape, angle and length of the ends directly affect fit, performance and service life. Straight Leg Ends Straight legs extend directly from the coil with no additional bends. They are simple and cost effective and work well when the spring [...]

When designing a tension spring, there are many factors to consider beyond the visual style of the end. Spring rate, how loads are measured at specific lengths, and the tolerances required for the application all influence how the spring will behave in its final assembly. These characteristics work together to create consistent, reliable performance Alongside these core parameters, choosing the right tension spring end type is an equally important step in achieving high-performance spring behaviour. In most tension spring [...]
