■ Characteristics The NWL/NWM Wire Springs feature a consistent spring constant based on their inner diameters. The load value is the same for all springs with a given inner diameter. ● Load calculation method: Load = Spring constant × Deflection (International Unit) N = N/mm × Fmm kgf = kgf/mm × Fmm (kgf = N × 0.101972) e The solid height values are for reference only. There may be some dispersions depending on the lot. e Operation frequency: 1 million shots e Product guide d P.1139 e Instructions and notes for coil springs d P.1142
