HEAT PROOF WIRE SPRINGS –WMH (40% DEFLECTION)/WHH (35% DEFLECTION)– ● HEAT RESISTANT UP TO 200°C.
■ Spring constant D Type
● N (load) = N/mm (spring constant) × Fmm (deflection) Load {kgf} = Load N × 0.101972 E No grinding on both ends of springs marked with ＊ E The solid height values are for reference only. There may be some dispersions depending on the lot. E Times used: 1 million E Instructions and notes for coil springs D P.1142 E • Coil springs marked with an asterisk have spring seat(s) on one end or both ends in order to reduce excessive stress or potential breakage when deflecting. (The seat becomes about 0.5–4 rolling extent.) Solid height and spring constant values are the same as those without spring seats. ｝ Seat

■ WMH: Fmax. (allowable deflection) = L × 40%
E Fmax. (Allowable deflection) is due to the measurement at normal temperature (40°C). Refer to P.1140 for the maximum allowable deflection at high temperature (150°C/200°C).
