Hollow springs are, among other things, used for supporting and structure-borne noise insulation in equipment manufacture and technology. They have vibration-insulating as well as shock-absorbing characteristics, which are also used in many different ways in the fields of vehicle construction and mechanical engineering. The range of applications for these spring elements are, for example, skid or landing gear springing in aircraft construction, in whirlers and jolters, for the separation of vibrating masses, as a shock protector in vehicle construction, or as an ejector in blanking coining and punching dies.
The elements are attached and secured with liners and/or flanges. All these products are maintenance-free.
