Level: 2
Grain Size
The special heat treatment optimizes the bearing microstructure and refines the grains, enhancing hardness, wear resistance, and service life. The treated martensitic structure reaches level 2, with grain size 10–11, compared to conventional heat treatment with martensitic structure level 3–4 and grain size 8–9.

Special Heat Treatment / Retained Austenite
After the special heat treatment, the retained austenite content in the bearing is less than 3%, minimizing the effect of austenite transformation on bearing precision during operation, ensuring stability and reliability for high-precision, high-load bearings.
