Also called the Simple Beam Spring, the bow spring is commonly manufactured from flat bar or strip. A bow spring is formed with an arc at or near the center and is supported on both ends with the force applied to the center of the arc.
A Cantilever Spring is made from the same materials but is clamped on one end while the force is applied to the other. Edge style of the material can play an important role in these springs; square edge, round edge, as milled or precision machined, depending on your application.
Spring Engineers can always provide the proper edge for your product.
