Tension Springs

Tension spring is a helical spring subjected to axial tension. There are different kinds of hooks. English hook, German hook, long hook, semicircle hook, duck bead hook and so on.  The “hook” is used to guarantee the source of tension of stretching spring. The gap for the ring and the ring must be tight and exact. These points must be identified. It is used to control the movement of machine parts , store energy, measure the size of the force and so on. Some of tension spring are made for precondition for safety.  That’s what we value and strict on quality control.  We must give more consideration to service this.
