For the selection of specification, please compare the spring constants（loads）. The example below is for selection of specification with outer diameter 4mm and free length 40mm. Similarly, more coil springs with different loads could be easily found out. 2Select the specification based on designing load. Select the range of spring constant （load） according to design, and then look up the compatible specification according to installation space.The example below is for selection of specification with spring constant 2.9N/mm. Similarly, more coil springs matching the designed spring constant （load） could be easily found out. Specific pagesWire SpringsCoil springs（high deflection）Coil springs（for heavy load）Coil spring has been widely applied for striper bolt, lifter pin, and knockout pin in press die. Designers need to consider the installation space, load, and life-span of spring, and then select the compatible products from over 3200 types. In order to lookup conveniently, the specification table is designed based on max. deflection and load, in terms of product codes. 1Select the most compatible load specification based on installation space. 2Select the most compatible installation specification based on designing load.Furthermore, the specification tables in the catalog can be used as supporting tool for designing, in order to benefit product selection.Selected specification with outer diameter 4, free length 40 ［directions and precautions for coil springs］ （ P.930） For details, refer to the specific page please.
