The bearing base, typically made of 08MnCuNiV cast steel due to its excellent impact resistance and corrosion resistance—making it particularly suitable for marine environments—is the core load-bearing component of the white metal bearing system. It is primarily used to install and support the white metal bearing bushings, and stably transmit the loads generated by the shaft system during operation to the equipment foundation or base structure.
The 35 Steel Bearing Seat for White Metal Bearing Systems adopts 35 cast or forged steel matrix with optimized load distribution design, which has extremely high tensile strength and deformation resistance. It can stably bear the radial and impact loads generated by the continuous operation of the marine shaft system, and avoid structural fatigue under long-term heavy load conditions.
Precision machining ensures a perfect fit with the upper bearing housing, white metal bearing liner, thrust shaft and sealing structure. Strict geometric tolerance control ensures stable alignment of the shaft system during long-term continuous operation, reducing vibration and wear of the entire transmission system.
It is fully adapted to the harsh marine conditions of high humidity, high salt spray and variable loads. The structural design reserves corrosion resistance margin, and full-process inspection ensures no manufacturing defects, greatly extending the equipment maintenance cycle and service life.

The Marine Propulsion System Bearing Seat is mainly suitable for the main propulsion shaft systems of ocean-going cargo ships, inland waterway transport vessels and offshore engineering ships. It is also widely used in white metal bearing systems of marine water turbines, steam turbines, heavy industrial rotating equipment and generator sets. It can meet the load-bearing bearing base requirements of various fixed and mobile industrial equipment, and provide stable load transmission solutions for core rotating equipment in industrial and marine fields.
We prioritize 08MnCuNiV as the blank, which has excellent welding performance, machinability and impact resistance, meets marine-grade material standards, and can adapt to long-term service requirements in marine environments.
Blank pretreatment and milling: High-precision milling of the bearing housing surface to ensure dimensional accuracy and flatness requirements;
Precision drilling: Strictly control the hole position accuracy and hole spacing consistency to meet the bolt connection and positioning requirements of subsequent assembly;
Precision boring and inner circle machining: Focus on controlling the roundness, coaxiality and surface accuracy of the inner hole to ensure a perfect fit with the white metal bearing liner.
We provide fully customized machining services for industrial buyers. We can carry out customized production according to the drawings and technical parameters provided by customers, for different equipment structural forms and working conditions, and also provide joint design services to fully optimize the load distribution, structural rigidity and assembly accuracy of the bearing at the design stage. At the same time, we can provide full system supporting components such as upper bearing housing, white metal bearing liner and sealing components, realizing one-stop procurement and reducing the supply chain management cost of customers.
After completing the main machining process, the lower shell of the bearing seat will undergo surface penetrant testing (PT) to check for cracks or manufacturing defects on the outer surface and critical areas, in order to ensure structural safety and long-term operational reliability. For application scenarios with high requirements for sealing performance and assembly quality of white metal bearings, the product can also undergo kerosene leakage testing to further verify the processing and assembly quality through sealing testing of the joint surface and key parts.
After completing all processing and testing procedures, the lower shell of the bearing seat will be cleaned and protected to prepare for the subsequent assembly of the white metal bearing liner and the installation of the entire bearing system.
Relying on advanced processing equipment and strict quality control system, our company can process or jointly design the lower shell of the bearing seat according to the drawings and technical parameters provided by the customer, ensuring stable and reliable fit between it and the upper shell of the bearing seat and the white metal bearing components. This product is widely used in various white metal bearing systems and is one of the important basic components to ensure the safe and smooth operation of the shaft system.
To protect the product from impact, corrosion or deformation during long-distance transportation and multiple handling operations, we adopt a multi-layer export-grade protective packaging solution:
Inner protective layer: All critical surfaces such as machined surfaces, mating surfaces and end faces are coated with anti-rust oil and fully wrapped with VCI vapor corrosion inhibitor paper to isolate air and moisture;
Cushioning and fixation layer: The product is fully covered with cushioning materials such as pearl cotton and rubber pads around, and customized special support positioning blocks are installed inside the package to prevent the heavy casting from rolling or displacement;
Outer reinforced packaging: Reinforced export wooden cases with excellent load-bearing capacity are used, which are suitable for sea, land and air transportation around the world;
Customized service: The protection level, fixed structure and outer packaging logo can be customized according to customer requirements to meet the needs of different destination ports and project sites.
