FRed® engine seal: less friction, less consumption

The latest developments with friction-reduced PTFE achieve similar results with even greater strength.

Many new developments in engine and drive train engineering focus on the mechanical efficiency of drive components and reducing mechanical losses. Radial shaft seals rings (RSSR) create strong friction, especially when the rings are large. KACO's answer to this problem is FRed® (friction-reduced oil seals). The innovative shaft seals rings reduce friction losses in car engines by more than 50%. The very low friction and the lower weight lead to lower fuel consumption and CO2 reduction, with the added benefits of minimised wear on the sealing lip and less shaft break-in.

FRed® (friction-reduced oil seals) engine sealing in comparison: the highly flexible sealing lip reduces the friction moment and it therefore reduces friction losses by up to 50 percent compared to conventional solutions.
