SEFKO/OTT Germany Spindle Spring/Double Helix Spring 33*15*77.5

Helical disc spring consists of two identical flat wire compression springs, which are twisted together helically to achieve a cross-section similar to that of a disc spring stack. The continuous flat wire structure avoids the molecular structure damage caused by stamped parts, thereby enhancing the durability of the component while reducing the risks associated with misalignment and breakage of disc spring plates. The increase in load is proportional to the bending stress of the helical spring steel. We can also achieve inclined winding of the helical disc spring during the coiling process to exhibit the characteristics of a compression spring while achieving the high load characteristics of a disc spring stack.

Overview of Basic Advantages:

•Single-component design, not split into individual plates, avoiding the misalignment phenomenon that occurs during the use of traditional disc spring stacks;
•Easier and lower-cost assembly and maintenance;
•Achieves extremely high spring load with a small outer diameter and low elastic hysteresis;
•Avoids force value errors caused by incorrect stacking methods or oil application;
•Continuous steel strip structure ensures longer-lasting performance;
•Higher operational safety, 
•Spring performance can be designed according to customer requirements;
•Avoids friction between the spring and guide rod or sleeve, allowing for guide rod-free operation;
•Adaptable to extreme working environments and temperature changes;
•Flexible and economical production capacity accepts orders of any quantity;
