Product Description

Product Description

High Precision Thrust Tilting Pad Babbitt Bearing for Steam Turbine Generator Tolerance 0.02mm, Ra≤0.32

The tilting pad bearing is a critical support component for steam turbines and is widely used in high-speed rotating machinery. Its core characteristic lies in the ability of each pad to tilt freely around its pivot, thereby automatically forming a convergent oil wedge during operation and generating a stable oil film pressure.

Compared with conventional fixed pad bearings, the tilting pad bearing offers higher oil film stability, effectively suppresses oil whip, and significantly improves the dynamic stability of the rotor system.

This product is suitable for steam turbine applications involving high rotational speeds, high loads, and variable operating conditions, making it an essential guarantee for long-term safe and stable operation of the unit.

Machinery Processing

Machinery Processing

The manufacturing of tilting pad bearings demands high levels of equipment rigidity, process control, and machining experience. The typical process flow is as follows:

1. Bearing Housing Machining

The bearing housing blank is made of forged copper alloy or high-quality carbon steel. Rough machining is first performed on a large CNC lathe, with machining allowance reserved for subsequent finishing.
Semi-finishing is then carried out to control the outer diameter, inner bore, and end face dimensions, ensuring that all reference surfaces meet process requirements.
2. Tilting Pad Machining

The inner bore surface of each tilt pad is machined with strict control over roundness, cylindricality, and surface roughness to ensure uniform oil film formation.
The spherical or cylindrical pivot surface is precision ground to ensure smooth and free tilting movement of the pad without sticking.
3. Assembly and Selective Fitting

The tiltes are trial-assembled with the housing to check the consistency of pad height and circumferential clearance.
Selective fitting is performed based on assembly results to ensure that the bearing inner bore roundness and the clearance between the pads and the journal meet design specifications.

Product Inspection

Product Inspection

To meet the high reliability requirements of steam turbines, the tilting pad bearing undergoes the following inspections after finish machining:

1. Dimension and Form Tolerance Inspection

Bearing inner bore diameter, outer diameter, end face dimensions, and critical fit areas are inspected.
At the same time, inner bore roundness, cylindricality, coaxiality, and pad pivot position accuracy are measured to ensure all parameters comply with drawing specifications.
2. Tilting Pad Flexibility Inspection

Each pad is manually checked for free tilting movement around its pivot to confirm there is no sticking or abnormal resistance, ensuring that the pads can self-adapt to journal position changes during operation.
3. Contact Spot Inspection

A contact check is performed between the pad inner bore and a test journal using marking compound to confirm that the contact area and distribution meet technical requirements, avoiding localized overload.
4. Final Cleaning and Re-inspection

The finished product is ultrasonically cleaned to remove machining residues, followed by re-inspection of critical dimensions to ensure cleanliness and accuracy meet shipping standards.

Packaging & Shipping

Packaging

To ensure that the product is protected from impact, corrosion, or deformation during long-distance transportation and multiple handling operations, a multi-layer export packaging solution is adopted, as detailed below:
1. Inner Protective Layer
All critical surfaces of the product (such as machined surfaces, mating surfaces, end faces, etc.) are coated with anti-rust oil or suitable protective agents and wrapped with VCI (Volatile Corrosion Inhibitor) paper or other protective materials. This effectively isolates air and moisture, preventing corrosion or damage during transportation and storage.
2. Cushioning and Fixation Layer
Cushioning materials (such as pearl cotton, foam, or rubber pads) are applied around the product to provide full protection. Customized supports or positioning blocks are also used inside the packaging case to prevent rolling or displacement of the product, ensuring stability during transport.
3. Outer Reinforced Packaging
The outer layer uses a reinforced export wooden case or other sturdy packaging with strong structural integrity and high load-bearing capacity, suitable for sea, land, or air transport. Handling marks such as center of gravity, lifting points, moisture protection, and anti-tilt symbols can be applied according to customer requirements, facilitating on-site handling and identification.
4. Customized Packaging Options
Packaging solutions can be customized according to customer requirements, including protection grade, cushioning method, fixing structure, and outer case design, to meet different transportation conditions, destination ports, and project site requirements.
