Your Benefits
RINGFEDER® Friction Springs have a number of superior advantages compared to conventional damping solutions:

High spring work at low weight and volume – As RINGFEDER® Friction Springs make full use of the spring material, dimensions and weight are reduced to a minimum. The decisive factor here is the spring work.
High damping capability – The damping of the RINGFEDER® Friction Springs is 66% as standard, which means that the energy introduced is quickly absorbed and resonance effects are suppressed completely. Variations in damping between 33% and 66% are possible by using other lubricants specific to the customer and application.
Spring work and damping effect independent from load speed – The force-stroke diagram of the RINGFEDER® Friction Springs applies for all operating conditions. In contrast to other damping systems, RINGFEDER® Friction Springs provide full spring work and damping effect even when the load is applied extremely slowly or quickly.
Overload-safe in block position – RINGFEDER® Friction Springs are generally designed to “block”, so it is therefore ensured that the admissible stresses cannot be exceeded and the RINGFEDER® Friction Springs will not be damaged.
Temperature-independence – In hydraulic dampers or synthetic springs, the force-stroke diagram is influenced by temperature fluctuations and inherent heating. The characteristic curve of RINGFEDER® Friction Springs is constant in the temperature range -20 °C to +60 °C. The self-heating of the spring due to damping must be taken into account. For applications outside the temperature range mentioned, please contact our experts.
Maintenance-free – Generally, relubrication of the operating RINGFEDER® Friction Spring is not required. Use of other lubricants may even lead to spring failure.
