Taper-land Thrust Bearings are fixed-profile hydrodynamic bearings for axial load support in large rotating machinery. Their tapered land geometry provides a compact, application-specific solution for equipment manufacturers and industrial bearing replacement projects.
Custom bearings are available for OEM applications and replacement projects, subject to drawing review and operating requirements.
Design Features
Tapered Land Geometry
The fixed tapered land profile is designed to generate hydrodynamic pressure as the thrust disc rotates. Land geometry and clearance are selected according to operating speed, axial load, and lubricant properties.
Babbitt-Lined Thrust Surface
A Babbitt alloy working layer provides a conformable surface for contact with the lubricating oil film. Alloy selection and lining thickness depend on the bearing design and service conditions.
Hydrodynamic Oil-Film Formation
The rotating thrust disc draws lubricant into the tapered clearance, generating pressure to support axial loads and separate the working surfaces. Stable film formation depends on speed, load, oil viscosity, and adequate lubricant supply.

Materials & Manufacturing
Base Material Selection
Carbon steel, cast steel, bronze, or stainless steel can be selected according to structural and service requirements.
Babbitt Lining and Bonding
Tin-based Babbitt alloy or an approved alternative is applied by centrifugal or static casting, depending on the bearing design. Substrate preparation and bonding procedures follow the specified manufacturing requirements.
Precision Machining
CNC machining and precision turning establish the required dimensions, clearances, and tapered working profile according to approved drawings.
Applications
Steam and Gas Turbines: Supports axial rotor loads and helps maintain the required rotor position during operation.
Centrifugal Compressors: Provides hydrodynamic thrust support for high-speed rotating assemblies operating under defined lubrication conditions.
Pumps, Motors, and Gear Equipment: Can be manufactured for axial-load support in industrial rotating machinery, subject to bearing design and operating requirements.
Power Generation Equipment: Provides thrust-bearing support in rotating equipment requiring continuous operation and controlled axial positioning.
Customization
Drawing-Based Manufacturing
Custom bearings can be manufactured from customer drawings, existing samples, or measured dimensions.
Design and Replacement Assessment
The tapered land profile, clearances, dimensions, materials, and lining specifications are reviewed against the original bearing design and operating conditions.
Pre-Production Confirmation
Drawings, critical dimensions, material specifications, and applicable inspection requirements are confirmed before production.
Quality Control
Inspection Items
Dimensional Inspection: Critical dimensions are checked against approved drawings.
Material and Hardness Testing: Conducted where specified in the order requirements.
Bonding Inspection: The Babbitt lining-to-substrate bond is inspected according to the agreed quality requirements.
Ultrasonic Testing (UT): Available for assessing lining bond integrity when required.
Inspection Documents
Dimensional inspection reports, material certificates, and UT reports can be supplied where applicable and agreed before production. Inspection scope and acceptance criteria are confirmed during order review.
FAQ
Q: What information is needed for a quotation?
A: Please provide the bearing drawing and revision number, key dimensions, equipment model, operating speed, axial load, material requirements, and order quantity. Lubrication details are helpful for technical assessment.
Q: What is the minimum order quantity (MOQ)?
A: MOQ depends on the bearing design, material requirements, and production process. Please share your requirements for confirmation.
Q: What is the typical production lead time?
A: Custom bearings typically require several weeks after drawing approval and material confirmation. The actual lead time depends on design complexity, material availability, and order quantity.
