Through-Hardening Ready Soft-Turned Bearing Rings

Tapered Roller Bearing (TRB) Rings are critical Structural Components in wind power equipment, designed to withstand combined radial and axial loads. Through-hardening TRB rings are processed using a quenching treatment, forming a martensitic hardened structure that provides excellent load capacity, superior fatigue resistance, and long service life. The through-hardening process ensures uniform hardening throughout the workpiece, preventing soft zones and enhancing cost-effectiveness and process reliability for large wind turbine Bearing Rings.

Our soft-turned bearing rings for through-hardening TRB applications are high-quality forged components, serving as the ideal base for final through-hardening processes in tapered roller bearings. Designed for wind turbines, Heavy Machinery, and industrial power systems, these rings provide precise dimensions, uniform geometry, and defect-free material, ensuring that the final through-hardened bearing achieves maximum load capacity, long service life, and fatigue resistance.
