Product Overview

■Product comparison information
♢ Economy series tension springs are manufactured overseas, resulting in significant cost reductions.
♢ Economy series tension springs are standardized to maintain the maximum load constantly to the same diameter. Initial tension and spring constant are for reference only.
♢ E-GAU□ is a stainless steel spring, but it is magnetic. Please be careful.

Note

[Cautions for Use]
▶Operating Temperature
SWP-B:: Ambient Temperature (0 to 40°C)
Stainless Steel:: ₋10 to 100°C
* Load value attenuates when tension springs are used in temperature higher than above, although it depends on other conditions.
* If this product is to be used in environments with extreme temperature difference or humidity such as outdoors, stainless steel is recommended.

▶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.
· Stainless Steel Spring is magnetic. Please be careful.
