The Solid Height of a compression spring is the height of the spring when all of the coils are brought together (stacked) by compression (load). Solid Height should only be specified when it is important to the function of the spring. It should be specified as a maximum allowing the spring...

The active coils are what make a spring a spring. We normally refer to the coils that open in an extension spring, the coils that deflect or close in a compression spring and the coils that twist or wind up/down in a torsion spring as "active"....

The active coils are what make a spring a spring. We normally refer to the coils that open in an extension spring, the coils that deflect or close in a compression spring and the coils that twist or wind up/down in a torsion spring as "active ". The active term should really be applied to any...

Squareness of a compression spring refers to the perpendicularity of the spring to its own axis. A spring that is "square" will exert more uniform loads, which may be needed in critical applications. Springs with ground ends generally offer better squareness than those with closed only ends...

) of the spring. There are times when the direction of wind is very important, especially on torsion springs where the spring should close up (tightens up) during deflection (movement). The end of an extension or compression spring may also screw onto a mating machined part, so the direction of wind...

Welcome back to the Ask the Expert Blog, where our engineers answer commonly asked ring and spring design questions. This week, our experts field some questions about wave spring substitutions, wave spring compression, and wave spring performance....

Spring manufacturing, as any other production process, is not exact. It can be expected to produce variations in such spring characteristics as load, mean coil diameter, free length, and relationship of ends or hooks. The very nature of spring forms, materials, and standard manufacturing processes...

As governed by Boyle's Law, P2 force is always greater than P1 force. During spring compression, the volume of rod introduced into the cylinder displaces an equal volume of gas, increasing the pressure in the cylinder and therefore the force of the spring. IGS standard springs are manufactured...
