Here is an overview of the different eyelet shapes for Extension springs<\/a> after DIN EN 13906-2: 2013<\/a> with the respective loop properties. Extension springs should only be subjected to static loads. If higher loads are planned, bent eyelets should be avoided and rolled or screwed-in end pieces should be used. Is useful at more stressed extension springs<\/a> also a life test under real operating conditions.<\/p>\n

With the respective Loop properties<\/strong> please note the dimensions, for example the 1\/1 German eyelet<\/strong> the value Lh<\/strong> (Distance between the inner edge of the eyelet and the spring body) only between 0.8 and 1.1 Tuesday<\/strong> (inner coil diameter). In addition, with the specification m<\/strong> the eyelet opening width can be specified.<\/p>\n
