[Cautions for Use]
▶Operating Temperature
SWP-B:: Ambient Temperature (0 to 40°C)
* Load value attenuates when tension springs are used in temperature higher than above, although it depends on other conditions.

▶Standard Usage Count: Approximately 700,000 times
* The above numbers are for reference only. The usage count may vary depending on the direction of tension, operating temperature/environment, and deformation amount.
 It is recommended to use the springs within 70 % of allowable deflection F max.(mm).

▶Others
· Use the springs within the range of the allowable deflection F max.(mm). Using at higher than the allowable deflection values may cause deformation or failure.
  Also, do not extend tension springs more than its allowable deflection during the installation.
