The most commonly used type of spring (70 percent) is<a href=\"https:\/\/blog.federnshop.com\/en\/information-compression-springs\/\"> Compression spring<\/a> ; it has the greatest resilience. In the<a href=\"https:\/\/blog.federnshop.com\/en\/information-extension-springs\/\"> Tension spring<\/a> the eyelet connection must be checked for extreme applications. With a simple one<a href=\"https:\/\/blog.federnshop.com\/en\/eyelet-shapes-extension-springs\/\"> 1\/1 German loop<\/a> the eyelet transition from the spring body to the eyelet is particularly sensitive.

The load limit of<a href=\"https:\/\/blog.federnshop.com\/en\/information-torsion-springs\/\"> Torsion springs<\/a> depends on the direction of loading and the shape of the leg. This is why the following applies to torsion springs: Load only in the direction of the coil; and the shorter the leg, the higher the load limit.<\/p>\n<h1><span class=\"ez-toc-section\" id=\"Spring_designs\"><\/span>Spring designs<span class=\"ez-toc-section-end\"><\/span><\/h1>\n<figure id=\"attachment_4985\" aria-describedby=\"caption-attachment-4985\" style=\"width: 150px\" class=\"wp-caption alignright\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-4985\" src=\"https:\/\/blog.federnshop.com\/wp-content\/uploads\/Bienenkorbfeder.jpg\" alt=\"Beehive spring\" width=\"150\" height=\"150\" data-wp-pid=\"1132\"><figcaption id=\"caption-attachment-4985\" class=\"wp-caption-text\">Beehive spring<\/figcaption><\/figure>\n<figure id=\"attachment_4968\" aria-describedby=\"caption-attachment-4968\" style=\"width: 150px\" class=\"wp-caption alignright\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-4968\" src=\"https:\/\/blog.federnshop.com\/wp-content\/uploads\/Tonnenfeder.jpg\" alt=\"Barrel spring\" width=\"150\" height=\"150\" data-wp-pid=\"1133\"><figcaption id=\"caption-attachment-4968\" class=\"wp-caption-text\">Barrel spring<\/figcaption><\/figure>\n<figure id=\"attachment_4952\" aria-describedby=\"caption-attachment-4952\" style=\"width: 150px\" class=\"wp-caption alignright\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-4952\" src=\"https:\/\/blog.federnshop.com\/wp-content\/uploads\/Konische_Druckfeder.jpg\" alt=\"Conical compression spring\" width=\"150\" height=\"150\" data-wp-pid=\"1135\"><figcaption id=\"caption-attachment-4952\" class=\"wp-caption-text\">Conical<\/figcaption><\/figure>\n<figure id=\"attachment_4949\" aria-describedby=\"caption-attachment-4949\" style=\"width: 170px\" class=\"wp-caption alignright\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-4949\" src=\"https:\/\/blog.federnshop.com\/wp-content\/uploads\/Zylindrische_Druckfeder.jpg\" alt=\"Cylindrical compression spring\" width=\"170\" height=\"150\" data-wp-pid=\"1138\"><figcaption id=\"caption-attachment-4949\" class=\"wp-caption-text\">Cylindrical<\/figcaption><\/figure>\n<p>In addition to the distinction between compression springs, tension springs and torsion springs, metal springs can be used in<a href=\"https:\/\/blog.federnshop.com\/bauformen-metallfeden\/\"> different designs<\/a> getting produced. The most common spring design is the cylindrical design, which delivers the force evenly with a linear spring characteristic. In addition, there are countless other designs such as the beehive spring and the conical or double-conical spring shape, which are used with variable spring characteristics for a wide variety of special tasks. For example, beehive springs with an upwardly tapered coil are often used for demanding dynamic applications.<\/p>\n<h1><span class=\"ez-toc-section\" id=\"Spring_material\"><\/span>Spring material<span class=\"ez-toc-section-end\"><\/span><\/h1>\n<p>The selection of the right material is essential in extreme use. In addition to the<a href=\"https:\/\/blog.federnshop.com\/en\/spring-steel-properties\/\"> Material selection<\/a> It is primarily corrosive, electrically conductive or non-magnetic as well as high and low temperature properties<a href=\"https:\/\/blog.federnshop.com\/en\/spring-steel-properties\/\"> Material properties in the modulus of elasticity (E) or in the sliding module (G)<\/a> , after which the spring provides the desired force and returns to its original shape when the load is removed. For this purpose, high elasticity limits are low for a large elastic range<a href=\"https:\/\/blog.federnshop.com\/en\/relaxation-for-springs\/\"> Relaxation properties<\/a> Even at elevated temperatures, a high fatigue strength, sufficient deformability and a smooth surface are essential. The<a href=\"https:\/\/blog.federnshop.com\/en\/spring-steel-properties\/\"> Spring steel wire 1.4568<\/a> according to DIN EN 10270-3, for example, offers constant material properties at +121 to -156 degrees.
