Constant force springs, also known as equal force springs.
It is made of multi-layer windings of steel strip, and the rings are closely attached to each other in a free status. This kind of springs bear tension, and its spring force can remain almost unchanged in long-distance stretching. When in use, apply a tensile force and release it, and it will automatically roll back due to the elastic force. Due to the large contact area of the steel strip, a constant linear force can be maintained within the effective stroke, and excellent balance, ductility and resilience can be exerted in a very small device space.
The life cycle of the constant force spring is counted once when the whole or part of the spring makes the reciprocating motion of extending and retracting. The service life is predictable. Springs with too high or too low service cycles will cause losses. It is a waste if the constant force springs have too much high life cycles; if it is with a lower service cycle, it will cause premature failure or malfunction. Therefore, it is very important to choose the right spring force. We can test the tensile force according to customer needs to ensure that it can maximize its value.
