• MISUMI Tension Springs (except for Specifed Types) are standardized to maintain the maximum load constantly to the same diameter. Produced based on the maximum load value, the initial tension and spring constant are reference values. • Use the springs within the range of the allowable defection F max.(mm). Using at higher than the allowable defection values may cause deformation or failure after a few uses. Also, do not extend tension springs more than its allowable defection during the installation. EFor Tension Springs durability can not be shown because stress concentration may occur depending on the hook installation. It is recommended to use the springs within 70 % of allowable defection F max.(mm). • It is recommended to use the tension springs (AW#, BW#, AWFM, WFSP, LWS, LWSH) under ambient temperature (at 40°C or less). Load value attenuates when tension springs are used in temperature higher than 40°C, although it depends on other conditions • MISUMI Round Coil Springs are standardized to maintain the spring constant constantly to the same diameter. The tolerance of spring constant is ±10%. Irregular shaped coil springs are standardized to maintain the maximum load constantly to the same diameter. The load tolerances vary depending on the spring type, please refer to the respective page. • Use the springs within the range of the allowable defection F max.(mm). Using at higher than the allowable defection values may cause deformation or failure. •The values of solid length are for reference only. Using it compressed to the solid length may cause deformation or break after a few uses.
