| Wire diameter d: mm | (Note: the diameter of the spring wire) |
|
| Outer diameter D2: mm | (Note: the diameter of the outer circle of the spring) | |
| Pitch t: mm | (Spacing between two adjacent circles) | |
| Number of circles Na: circle | (Note: the total number of turns of the spring) | |
| To customize the sheath spring, you also need to provide the following technical requirements: | ||
| turn around: | (Description: Left-handedRight-handed) | |
| Material requirements: | (Such as: stainless steel wire SUS, carbon steel wire SWC, piano wire SWP, copper wire... etc.) | |
