Description

Minimum hardness of the shaft: 160 HB Good sliding properties at mean load and high to low sliding velocities in the hydrodynamic range. Good impact stress. Sensitive to reversed bending stress and edge compression. High wear resistance in the case of rough journals (grey cast iron). Used for plain bearings for turbines, compressors, electric machines and gears.
