Applied to various mechanical devices and consumer products requiring tensile return force, it delivers stable axial tension output through double loop-end connections, ensuring precise resetting.
Precision cold-wound from high-quality carbon steel or stainless steel wire with tightly closed coils, this spring incorporates an initial tension that provides a pre-load force before extension begins, eliminating motion slack and enabling smoother force transmission. The full-circle loop ends are precision-formed for high strength and deformation resistance. The phosphate blackening surface treatment provides reliable rust protection, while consistent geometry is maintained across all size variants
Application areas: Door and window lock return mechanisms / Small appliance internal linkage systems / Toy and model drive mechanisms / Industrial fixtures and clamping devices / Medical device opening and closing mechanisms
