Stainless steel extension springs are spiral tension springs that can withstand axial tension. Stainless steel extension springs are generally made of round cross-section materials. When not under load, the rings of stainless steel extension springs are generally tight and there is no gap.
Stainless steel extension springs are generally of equal pitch, and the cross section is mostly round. They can be used in many occasions, such as production and installation, experimentation, research and development, and repair.
Tension springs occupy an important position in the global market and are widely used in marine, computer, mechanical engineering and other fields. Many different terminal devices or "hooks" are used to ensure the origin of the tensile force of the stainless steel extension springs. The working principle of stainless steel extension springs is opposite to that of contraction springs. The contraction springs have a reverse effect when they are compressed, while stainless steel extension springs have a reverse effect when they are stretched or opened.
When the two ends of the stainless steel extension springs are opened, the springs will pull them back together. Like contraction springs, stainless steel extension springs also absorb and store energy, but unlike contraction springs, most of the stainless steel extension springs are usually under a certain degree of tension, even without any load. This initial tension determines how tightly the stainless steel extension springs are coiled without any load.
