Pad Thrust Bearings are sliding bearings designed to support axial loads in large rotating equipment. A lubricating oil film forms between the thrust pads and thrust disc during operation, separating the working surfaces under appropriate operating conditions.

Product Structure & Design Options
Thrust Pad Assembly
Thrust pads support axial loads through a lubricating oil film between the pads and thrust disc. Pad geometry, quantity, arrangement, and working clearance are determined by axial load, operating speed, lubricant properties, and operating temperature.
Fixed-Pad and Tilting-Pad Designs
Fixed-pad and tilting-pad designs are available for different bearing configurations. Tilting pads pivot independently to adapt to changes in the oil film during operation. The appropriate design depends on the equipment requirements and original bearing configuration.
Bearing Configuration
Bearing structure, mounting features, and interface dimensions are defined by the approved design to ensure compatibility with the equipment.
Materials & Manufacturing Process
Base Material Selection
Carbon steel, cast steel, stainless steel, and bronze are available for bearing components. Material selection depends on component requirements and the specified design.
Babbitt Alloy Lining
Tin-based and lead-based Babbitt alloys are available for bearing working surfaces, subject to the required alloy grade and project specifications.
Precision Machining
CNC machining, boring, and precision finishing are used to achieve specified dimensions, tolerances, fits, and surface requirements.
Babbitt Casting and Bonding
The substrate is prepared before Babbitt alloy casting and bonding. The lined surface is then finished according to the specified requirements.
Applications & Equipment Compatibility
Power Generation Equipment
Suitable for axial rotor support in steam turbines, water turbines, and generators, subject to the bearing design.
Compressors and Pumps
Available for industrial compressors and pumps requiring axial load support.
Marine Equipment
Customized bearings can be supplied for marine propulsion systems and related rotating equipment according to the equipment requirements.
Quality Control & Inspection
Material Inspection
Material grades and chemical composition are verified against specified requirements. Material certificates and analysis reports can be supplied as agreed.
Dimensional and Surface Inspection
Critical dimensions, tolerances, fits, and working surfaces are inspected against approved drawings and agreed acceptance criteria. Dimensional inspection records can be provided as required.
Babbitt Bond Integrity
Babbitt bond integrity can be evaluated using suitable inspection methods. Ultrasonic testing (UT) and hardness testing can be arranged according to project specifications and applicable inspection requirements.
Quality Documentation
Material certificates, dimensional inspection reports, and applicable test reports can be supplied as agreed. Final acceptance is based on approved drawings, specified tolerances, and agreed inspection requirements.
OEM Customization & Supply Support
Drawing-Based Manufacturing
Production can be arranged from customer-provided 2D or 3D drawings, samples, or technical specifications. Technical details are reviewed before manufacturing.
Replacement Bearing Manufacturing
Replacement bearings can be manufactured based on available original parts or technical documentation. Any reverse engineering requirements are assessed before production.
Structural and Material Customization
Bearing configurations, pad quantity, base materials, and Babbitt alloy can be specified according to the approved design and project requirements.
Order and Export Support
Sample, small-batch, and bulk orders can be considered. Protective packaging, export wooden crates, shipping marks, and agreed shipping documentation can be arranged for international orders.
FAQ
Q: What information is needed for a quotation?
A: Please provide the bearing drawing or model, dimensions, equipment type, axial load, operating speed, operating temperature, lubrication conditions, material requirements, and order quantity where available.
Q: What are the MOQ and production lead time?
A: MOQ and lead time depend on bearing size, structural complexity, material availability, order quantity, and production scheduling. Final details are confirmed after technical review.
Q: Can you accommodate urgent delivery requirements?
A: Expedited delivery may be considered depending on material availability, manufacturing complexity, and the production schedule.
Q: What is the difference between a Pad Thrust Bearing and a Tilting Pad Thrust Bearing?
A: Pad Thrust Bearing is a general term for thrust bearings using bearing pads. Tilting Pad Thrust Bearings feature independently pivoting pads that adapt to changes in the operating oil film.
Q: Are spare parts and after-sales support available?
A: Spare parts, replacement components, and technical support can be discussed according to the original bearing design and project requirements.
