Already more than 30 years ago Röhrs developed a new spring assembly consisting of helical springs made of flat wire and screwed into each other. For this spring assembly the brand names “SCHRAUBENTELLERFEDER®” and "HELICODISC®" have been created and protected.
Since the 1980s Röhrs has been successfully selling spring assemblies of this brand on the market. Thus they are proven and tested machine components which in many cases replace the common multi-layer disc spring assembly. The uninterrupted gain structure of the raw material leads to an increased durability and reduces the risk of breakage of the HELICODISC® helical disc springs. In principle, the characteristics of any inversely layered disc spring assembly can be realized with a helical disc spring. The load increase is proportional to the deflection since there appears only bending stress in the spring steel.
