By working closely with the steel industry, bearings and condition monitoring specialist Schaeffler has co-developed a new, high strength quenched and tempered steel specifically for wind turbine slewing rings that are subjected to extreme loads during blade and tower adjustment.
This new material allows full tempering and quenching of the steel and, as a result, provides outstanding strength properties, even with large ring cross sections. Zinc thermal spray surfaces, multi-layer painting and finished seal surfaces also provide the highest levels of reliability, bearing rating life and security against premature damage, such as fatigue of the ra...
