We make a distinction as to whether this is a pure vibration damper (friction damper) or a vibration damper with integrated spring support (spring leg, suspension). These products are delivered in very high quantities to the worldwide producers of fully automatic washing machines (household and commercial). In addition, they are also used in various industrial applications.
When designing this friction damper, particular attention was paid to the variable lengths of the component and the diversity of end fittings. This allows for use in a variety of applications.

The damper offers an integrated Free Stroke System through which the friction force is only engaged at larger amplitudes. The design leverages an innovative configuration to use just the right amount of material for optimal price and performance. The RD 16 FL is a combination of Standard (RD 16) and Free stroke dampers (RD 18 FL).

The damper offers an integrated smooth-running system, whereby a gentle use of the damping occurs. This system results in tremendously smooth running and good stability, even in the event of high imbalances in washing machines. The RD 18 LL is a combination of standard (RD 18) and free stroke dampers (RD 18 FL).

A linear characteristic is guarantee by the integration of two additional springs into the known Free Stroke System (RD 18 FL). In addition, this damper is equipped with a distance / position sensor. The clever combination of a sensor and evaluation electronics can provide a signal that is easy to process. The sensor system allows for the load measurement and imbalance detection in washing units, for example.
