New rolling bearing material Mancrodur

Twice the operating life in heavy-duty operating conditions

Product description

With carbonitrided Mancrodur, Schaeffler has resolved a long-standing conflict of aims in the development of rolling bearing materials: The new steel, combined with carbonitriding heat treatment, offers both a greater surface hardness and a higher ductility compared to other steels. Mancrodur is therefore able to level out ridges in the raceway caused by embedded foreign particles. Material fatigue is considerably reduced and the formation of cracks is prevented. Especially in cases of poor lubrication or contaminants, this enables twice the standard operating life. Mancrodur is particularly suitable where greater machine capacity is required under tough operating conditions. In addition to the application areas already tested in steel works, this new high-performance steel has proven itself to be the material of choice in areas such as highly-loaded axlebox bearings in freight cars, planetary bearings in wind turbines and bearings in pumps and compressors.
