The bearing housing assembly is a vital load-bearing supporting component of steam turbine rotor systems. It accommodates journal bearings and thrust bearings, carries radial and axial dynamic loads transmitted from the rotating rotor, and forms an enclosed cavity for lubricating oil circulation. Its structural stability, machining accuracy, and oil-sealing performance directly affect unit vibration levels, bearing operating conditions, and overall running safety of the steam turbine.
We provide fully-customized bearing housing assembly solutions based on client-supplied drawings, unit specifications, and actual site operating conditions. Our products are widely applied in new-build power projects, turbine technical retrofitting, performance upgrading, and overhaul spare-part supply for various power generation facilities.
Material & Manufacturing Technology
We select high-strength cast steel or nodular cast iron compliant with turbine industry standards. The complete production workflow covers pattern making, casting, stress-relieving heat treatment, rough machining, multi-procedure non-destructive testing (UT, MT), high-precision CNC finishing, bearing-seat bore fine boring, oil-passage processing, oil-seal surface finishing, and assembly dimensional verification. Strict process control eliminates casting defects and removes residual stress to guarantee material stability and high-precision fitting dimensions.
Key Product Advantages
High Structural Rigidity & Superior Vibration Damping
Optimized rib-reinforced structure design effectively bears dynamic loads from high-speed rotating rotors, restrains vibration amplification, and maintains stable geometric accuracy under long-term alternating load conditions.
Precision-Machined Bearing Bore & Oil Passage
High-precision boring for bearing seating bore guarantees perfect fit with bearing shells. Reasonably arranged internal oil channels ensure smooth lubricating-oil flow, enabling effective lubrication and heat dissipation for bearings.
Reliable Oil-Sealing Performance
Accurately processed oil-seal mating surfaces and labyrinth-seal mounting seats effectively prevent lubricating-oil leakage and outside-air ingress, maintaining a clean and stable working environment inside the bearing chamber.
Full-range Customization Capability
Customizable overall outline dimensions, bearing bore size, oil-passage layout, anchor-foot interface, bolt hole distribution, thrust-bearing mounting structure, and sensor installation positions. Services include drawing-driven OEM production and reverse-engineering customization based on original unit parameters.
Strict Quality Control & Assurance
Each finished bearing housing assembly undergoes complete acceptance procedures: dimensional tolerance inspection, surface quality check, multi-item NDT non-destructive examination, and material certificate verification. Full traceable production documents are provided for customer acceptance.
Application Scenarios
Applicable for various-capacity steam turbine units used in:
Thermal power generation
Cogeneration plants
Metallurgical waste-heat power generation
Chemical self-owned power plants
Biomass power generation
Other energy-generation projects
