At CWP2026 China Wind Power Exhibition in Beijing, JUNHUAN showcased its complete portfolio of core wind turbine bearings. The product range covers three critical sections of wind turbine units including main shaft, gearbox and generator. From individual components to full series supply, the display highlights JUNHUAN technical capability across the whole chain of material, design, manufacturing and test verification.

One Customised Solution for One Working Condition

Each rotating position inside wind turbines operates under unique working conditions. Load type, speed range and reliability requirements vary significantly. JUNHUAN delivers targeted bearing solutions matching each installation site.

Main Shaft Section: Withstand Combined Loads and Long Continuous Operation

Bearings for main shaft positions need to sustain radial, axial combined loads and overturning moment. These products adapt to harsh environments for long continuous operation of large megawatt onshore units. Raceway precision, assembly clearance and lubrication reliability directly determine service life. Special heavy‑load designs are available for large megawatt applications to maximise load capacity within limited space.

Gearbox Section: Targeted Designs for High Speed End, Intermediate Stage and Compact Layout

Multiple bearing types are supplied for different gearbox positions. Selected structures absorb thermal expansion and assembly deviation during operation. Some designs provide high rigidity and strong impact resistance for stable power transmission. Compact bearing structures help reduce radial space and support lightweight transmission chain development.

Generator Section: Balance Operation Efficiency and Maintenance Free Cycle

Generator bearings feature low friction and high speed performance. Long‑life lubrication meets strict demands for high efficiency and extended maintenance free periods. Optional insulation coating protects bearings from shaft current damage and extends service life under variable frequency working conditions.

Integrated Capability to Support Special Product Spectrum

JUNHUAN dedicated wind bearing product system is built upon years of field engineering experience. Four core strengths support the full product spectrum.

– Material purity control: Vacuum degassing limits inclusions and segregation inside steel to improve raceway fatigue life.
– Heat treatment process: Carburising or induction hardening options are adopted for different application scenarios. Hardened layer depth, hardness gradient and microstructure are precisely controlled.
– Structural simulation and working condition test: Contact stress, cage movement and full machine performance are verified with real load spectrum before formal application.
– Precision machining and inspection: High‑precision grinding ensures raceway quality. Full‑process inspection maintains consistent performance among bearing batches.

Moving Toward Larger Megawatt Units and Deep Offshore Wind Power

Larger turbine capacity and deep offshore wind projects raise higher standards for wind turbine bearings. JUNHUAN accelerates product iteration and test work for high megawatt onshore and offshore wind markets. Technical knowledge gained from the exhibition guides future research and market planning.

Exhibition Site: Technical Sharing and Business Cooperation

JUNHUAN technical team explained bearing solutions and working condition matching at the booth. The team held in‑depth communication and cooperation talks with turbine manufacturers, operation maintenance providers and other industry visitors.
