Wire protection springs are widely used to protect cables, hoses, and flexible components from bending, crushing, abrasion, and mechanical damage. Our industrial protective springs provide strong protection while maintaining flexibility and easy installation. They are commonly used in hydraulic systems, electrical equipment, machinery, automotive applications, and engineering projects. Customized designs are available to match different operating environments.
| To customize the sheath spring, you need to provide the following necessary parameter information: | ||
| 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.) | |
