The TRB (Tapered Roller Bearing) ring is a
precision ring-rolled component engineered to withstand combined axial and radial loads. A complete tapered roller bearing assembly consists of an inner ring, outer ring, rolling elements, and a cage. In wind turbine applications, TRB
Bearing Rings play a crucial role in transmitting torque within the drivetrain—from the gearbox or rotor to the generator. Through optimized structural design, these rings improve torsional rigidity and operational stability, reduce deformation under heavy loads, and ensure long-term reliability of wind power systems.
TRB bearing rings are produced from high-carbon alloy bearing steel, selected in strict accordance with international bearing standards to guarantee uniform microstructure and defect-free performance even under extreme operating conditions.
The manufacturing process is centered around ring-rolling technology and includes:
-
forging Blank Preparation – High-quality steel is heated and formed into near-net ring shapes through ring rolling , refining grain flow and eliminating internal defects.
-
Precision Machining – Turning, drilling, and other finishing operations ensure tight tolerances and superior surface quality, meeting the requirements of wind turbine drivetrains.
-
heat treatment Optimization – Depending on steel grade, quenching & tempering or spheroidizing annealing is applied to enhance hardness, toughness, and fatigue resistance, enabling the ring to endure alternating and impact loads in operation.
Applications
- Wind Power Equipment – Main shaft wind turbine bearing rings for MW-class wind turbines, supporting the core transmission system.
- Heavy-Duty Machinery & construction equipment – Mining machines (continuous miners, tunnel borers), excavators, compactors, rolling mills, large conveyors, etc., where high combined loads exist.
- Industrial Power Transmission Systems – Large gearboxes, pumps, compressors, and high-reliability heavy-load applications.
- Energy & Power Generation Equipment – Hydropower turbines, thermal power units, and auxiliary systems in nuclear power plants.
Key Advantages
- High Strength & Fatigue Resistance – Ring rolling combined with heat treatment delivers excellent torsional strength and long fatigue life, supporting continuous high-load operation in wind turbines.
- Precision Fit & Low Vibration – Tight dimensional control ensures perfect alignment with mating transmission components, reducing vibration and noise.
- Wide Specification Range – Net weight from 100 kg to 6 tons, with minimum diameter ≥ 100 mm, covering multiple wind turbine power levels.
- Reliable Material Performance – Made from premium high-carbon alloy bearing steel, offering a balanced combination of toughness, durability, and extended service life after heat treatment.
