Extension Springs

Our extension springs have been specified and designed to high precision standards. We refer to DIN 2089-2/EN13906-2. All our standard extension springs have uniform body diameter and are produced with full twist loops the same diameter as the body. They are wound with initial tension; some force is required before the coils are initially separated. As with other stock components, they are capable of wide application for experimental, development, protyping, and maintenance work.

TEVEMA produces extention springs with Full German loops, English loops, hook loops, etc. according to DIN 2097-3.

Special Extention Springs


Our production department can make almost every extention spring on measure in as well small as large quantities. The extention springs can be made with different ends, which you can find in DIN 2097 site 3. We can produce them from different materials such as music wire, stainless steel 302 or 3.16, exotic materials like inconel, ninomic, fosfor bronze, beryllium copper (CuBe2), molybdeen, wolfram, titanium etc. Our engineering department can help you to find the right spring. We can also take care for different after treatments like passivating, epoxy coating, chemical blacking, chromium plating, nickel plating, electrolitical polishing, sink plating, silver plating, gold plating, cleanroom packaging etc.
