• Flange part of the spring and holder is press fitted. However, the spring and holder could come off depending on the usage environment. Please refrain from using the spring in an unlocked state. Please use with initial deflection. • Please use it withing the maximum allowable deflection. It makes it easy for the spring and the holder to come off easily and it is very dangerous. • Use within the allowable temperature. • Data on load was taken at room temperature (less than 40°C). Although it may vary depending on various conditions, N{kgf} load usually decreases when used in temperature higher than room temperature. ● Load calculation method: Load = Spring constant × Deflection N = N/mm × Fmm kgf = kgf/mm × Fmm E Instructions and notes for coil springs D P.1142
