Garter Springs and
Die Springs

Garter springs and die springs have many common uses in household and industrial applications. They come in a variety of sizes, thicknesses, and materials, allowing you to custom-design a spring according to your budget and intended uses. We custom-create garter springs and die springs according to your specifications and needs.

What are Garter Springs?

Garter springs are usually made of carbon or stainless coiled steel, and they connect at each end in order to form a circle. There are two types of garter springs: compression and extension. A compression garter spring exerts an outward radial force, while an extension garter spring exerts an inward radial force. The manufacturing process is no different from that for a regular spring, with the exception that the ends join. Commonly, a garter spring is used to maintain lip seal pressure on a shaft, but it may also be used in a drive belt or in an electrical connection.

Garter Spring Manufacturing Process

First, reels of steel are cut to produce normal springs, the strength of which directly relates to the thickness, or gauge, of the wire. In a compression spring, there are spaces between the coils, allowing them to expand and contract as needed. Conversely, there are no spaces between the coils of an extension spring. Next, the ends of the spring join to create a circle shape. The spring ends join in a number of ways, too. The manufacturer may use loops at both ends of the spring, use a connector made of a hook and loops, or create a nib joint so that one end of the spring is smaller than the other, allowing it to interlock.

What are Die Springs?

In line with their name, die springs are typically found in die machinery, and they are heavy-duty in nature. They come in a variety of materials, including oil-tempered metals and chrome alloys. You can utilize die springs in just about any application where you anticipate high stress loads or when you need a long lifecycle. Choosing a die spring, or even designing a die spring for your unique application, requires some consideration. You will need to determine the rate of cycling, the length of runs, and the amount of stress that will be placed on the spring.

Die Spring Size

It is also important to consider the "hole size" when you order die springs. The hole size does not refer to the diameter of the spring itself; rather this is the diameter of the installation hole. Because the spring must be able to work freely without hindrance, meaning it should not rub against the walls of the hole, you must consider the diameter of the hole the spring can work in when placing your order. It is also important to remember that your die springs should be installed pre-tensioned as this avoids shock loads that may break the springs or cause harm to the machine or its operator.

If you need garter or die springs in common sizes and styles, or if you need custom-designed springs to suit your original machinery, we can help. Just contact us with your specifications and we will work to provide you the perfect springs for your needs.
