Tilting Pad Thrust Bearing Assembly

The Tilting Pad Thrust Bearing Assembly is designed to support axial loads in rotating machinery, including steam turbines, compressors, generators, and pumps. Its tilting pads form a hydrodynamic oil film between the pads and thrust collar to support axial loads under specified operating conditions.

Tilting Pads: Support axial loads through a hydrodynamic oil film. Pad quantity, geometry, and lining requirements are determined by the design.

Carrier Ring or Retaining Structure: Holds and locates the pads within the assembly.

Pad Pivot Components: Allow the pads to tilt according to the specified support design.

Supporting and Locating Components: Provide the required positioning and mounting interfaces where included in the assembly.

Assembly Configuration: Equalizing or non-equalizing designs can be evaluated according to equipment requirements and design availability. Single-direction or double-direction arrangements are determined by the required thrust support.

 Actual dimensions, materials, clearances, load capacity, operating speed, and other performance parameters are confirmed according to the approved design and operating conditions.

Base and Lining Materials

Carbon steel and bronze are available for specified bearing components. Tin-based Babbitt alloy can be used as the working lining for thrust pads. Material selection depends on the design, operating conditions, and customer specifications.

Precision Machining

Key components are machined to the specified dimensions and tolerances. Mounting interfaces and other critical features are checked against approved drawings.

Babbitt Lining Process

The substrate is prepared before Babbitt lining. Lining application and subsequent machining are controlled to meet specified bonding, thickness, and surface requirements.

Surface Finishing and Protection

Machined surfaces are finished according to drawing requirements. Rust prevention and protective packaging are applied as appropriate for storage and transportation.

Material Inspection: Verify specified material grades and review available material documentation.

Dimensional Inspection: Check critical dimensions, tolerances, and mounting interfaces against approved drawings.

Lining Inspection: Check Babbitt lining condition and verify specified thickness, bonding, and surface requirements where applicable.

Component Inspection: Examine machined surfaces, contact areas, and visible defects.

Final Inspection: Verify the completed assembly and agreed supply scope against applicable drawings and purchase requirements.

Material certificates, dimensional inspection reports, and other quality documents can be supplied according to the purchase order and agreed inspection scope. Third-party inspection can be arranged by agreement.         

Custom Tilting Pad Thrust Bearing Assemblies can be manufactured according to customer drawings, samples, or available equipment information.

Customization may cover:

Assembly dimensions and mounting interfaces

Pad quantity and pad configuration

Base and lining materials

Specified lining thickness and machining tolerances

Equalizing arrangement and thrust direction, where supported by the design

Inspection requirements and accompanying documentation

For replacement projects, the original part number, equipment model, drawings, or sample can be provided for technical review. Critical dimensions and operating requirements should be confirmed before production.
