Fluid Film Thrust Bearings support axial loads in large rotating equipment by maintaining a lubricating oil film between the thrust pads and rotating thrust disc. The oil film reduces direct surface contact and wear while helping maintain the required axial position of the rotor.
Design & Construction
Thrust Pads
Thrust pads support axial loads through a lubricating oil film between the pad surfaces and the rotating thrust disc. Pad configuration is selected according to bearing design and operating conditions.
Bearing Housing
The housing supports the bearing assembly and provides the required structural stability and mounting interfaces for equipment installation.
Lubrication Arrangement
The lubrication arrangement maintains oil supply to the working surfaces. Its design is assessed based on bearing requirements and the equipment lubrication system.
Assembly and Installation
Critical interfaces and mounting features are designed to match approved drawings and equipment requirements, supporting proper alignment and installation.
Materials & Manufacturing Process
Material Selection
Carbon steel, cast steel, bronze and stainless steel are available for bearing components. Babbitt alloy or other specified lining materials are selected based on operating conditions, lubrication requirements and customer specifications.
Precision Machining
CNC machining, boring and other precision machining processes are used to achieve the required dimensions, fits and mounting features specified in approved drawings.
Babbitt Lining
The lining process includes substrate preparation, alloy application and bonding control. Centrifugal casting may be used where appropriate for the bearing design and manufacturing requirements.

Custom Manufacturing & Replacement
OEM Manufacturing
Fluid film thrust bearings can be manufactured to customer drawings, 2D or 3D models, samples and approved technical specifications. Structural details and material combinations can be adapted to equipment requirements.
Replacement for Existing Equipment
Replacement bearings can be assessed using existing drawings, samples, dimensional measurements or available structural information. Solutions can be evaluated for older equipment and imported machinery.
Engineering Support
Engineering review focuses on bearing configuration, material selection and installation compatibility. Available operating data and equipment requirements are assessed to determine the appropriate manufacturing approach.
Quality Control & Inspection
Dimensional Inspection
Critical dimensions, fits and mounting features are checked against approved drawings and agreed tolerances.
Babbitt Bonding Inspection
The Babbitt lining and substrate are inspected for bonding integrity according to applicable technical specifications and agreed acceptance criteria.
Non-Destructive Testing
Additional non-destructive testing can be arranged when required by the technical agreement or project inspection plan. Testing methods and acceptance criteria are confirmed before production.
Quality Documentation
Material certificates, dimensional inspection reports and other agreed quality records can be supplied according to purchase order requirements. Inspection scope and documentation are confirmed before production.
