About This Product

■Product overview

This is the most common spring. Store it in a case and use it. When placed in a case, adjacent coils are in contact with each other, causing frictional loss of energy, but on the other hand, torque remains stable. Because it has a large number of turns, it is used for applications with high rotational speed.

■General materials

・Hardened steel strip (SK85M, SK95M) ・Flat hard steel wire (SWRH77B) ・Stainless steel strip (SUS301, SUS631, SUS632J1)

■Main uses

Wall clocks, timers, toys, music boxes, metronome, recoil starters, roller chain tensioners, cord reel winding, earphone cord winding, dog leash winding, USB/LAN cable winding.
