The use of extension springs is extremely wide, from agriculture, through industry, to construction. As the name suggests, extension springs work on the basis of stretching. The key to long life and trouble-free operation is the extraordinary precision of workmanship. Our products retain their original properties for a very long time. Eibach has many years of experience in the production of the highest quality springs, which, combined with the use of the latest production technologies, has resulted in high-class products. Our extension springs are highly rated by professionals for whom failure-free and high work culture are particularly important.
The materials used in production are also important. Among others, we use patented drawn spring wire made of unalloyed steel, according to DIN EN 10270-1. In addition, we use oil-hardened spring wire for production, according to DIN EN 10270-2. As a manufacturer of tension springs, we also use stainless spring wire, according to DIN EN 10270-3. All of the above-mentioned materials allow for the so-called pre-tensioning.
As a spring manufacturer, we offer models on special request, also made of 51 CrV4 or 52 CrMoV4 materials, according to DIN EN 10089 standards. In both cases, after the hardening process, tempering takes place, immediately after shaping. It is worth knowing that such springs cannot be pre-stressed. If necessary, we also produce springs made of special materials such as Elgiloy®, Nimonic®, Hastelloy® and Inconel®. Extension springs can have different ends. We offer, among others, a bent handle, as well as handles mounted from sheet metal or cast iron, screw ends and many others.
We manufacture tension springs with wire diameters ranging from 4 to 20 mm. This wide range means that our products are successfully used in many industries. The entire technological process is perfected, so you can be sure that you are receiving a product that will 100% meet your expectations in every respect.
