Helical Disk Spring – Power Pack

This power pack is composed of a quadruplicated screwed together helical disk spring.
It is apllied in hydrogen fuel cells featuring a high energy density for instance (e.g. satellites / submarines)

The benefits include:

• Extreme high spring force by minimal outer diameter
  Example: With an outer diameter of 18 mm a spring force of 10 kN is achieved. With an outer diameter of 23 mm a spring force of 25 kN is achieved.
• Designs to meet customer requirements
• High lifetime and operational safety
• Easy and low-cost assembly and maintenance due to single component design
• Little hysteresis, minimal wear
