The hardenability and surface hardness of steel ShKh15SG are inadequate for large bearings with a wall thickness over 30 mm.
Additional alloying of steel ShKh15SG with 0.25–0.50% Mo increases the hardenability and the surface hardness.
The actual service life of ShKh15SGM bearings exceeds that of standard bearings by more than 50%.
Steel ShKh15SGM is recommended for large bearings in pivots and rotors.
