Product Description

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.


manufacturing process & quality control

Our soft-turned TRB bearing rings follow a fully traceable and strictly controlled manufacturing workflow:

  1. Incoming Material Inspection
  2. Blank Cutting
  3. ring rolling
  4. Post- forging Inspection
  5. Normalizing + Annealing heat treatment
  6. Heat Treatment Inspection (Hardness / Microstructure Verification)
  7. Mechanical & Chemical Properties Testing
  8. Rough Turning
  9. Semi-Finish Turning
  10. Comprehensive Quality Inspection:
    • Dimensional Inspection
    • Ultrasonic Testing (UT)
    • Magnetic Particle Testing (MT)
    • Spectrographic Chemical Analysis
    • Traceability Marking / Stamping
  1. Cleaning, Anti-Rust Coating, Packaging, and Storage
Note: These rings are delivered as soft-turned pre-machined blanks ready for the customer’s through-hardening process.
