The Spherical Combination Bearing is a custom-manufactured fluid-film bearing combining radial and axial load support in one assembly. It is designed for rotating equipment requiring specified load capacity, angular accommodation and application-specific dimensions.
Product Construction
Bearing Housing
The housing provides the main structural support for the bearing assembly. Carbon steel, cast steel and alloy materials can be selected according to load, operating conditions and dimensional requirements.
Spherical Sliding Surface
Spherical mating surfaces allow controlled angular movement within the bearing assembly, helping accommodate specified shaft alignment and installation deviations.
Radial and Axial Bearing Sections
Separate bearing surfaces support radial and axial loads within one bearing assembly, allowing both load directions to be accommodated at the same bearing location.
Sliding Layer
Sliding surfaces can use Babbitt alloy, bronze, bimetallic materials or PTFE composites. Material selection depends on load, speed, temperature and lubrication conditions.

Manufacturing Process
CNC Machining
Critical dimensions, bores and spherical surfaces are precision-machined according to the approved drawing or agreed specifications.
Babbitt Lining
For Babbitt-lined configurations, Babbitt alloy can be applied to steel or bronze base materials by centrifugal casting, followed by machining to the required dimensions.
Final Machining
After lining and surface processing, the bearing is finish-machined to the specified dimensions, clearances and mating geometry.
Applications
Heavy Machinery
Construction machinery, mining equipment and lifting machinery where bearings are exposed to high mechanical loads, shock or vibration.
Hydraulic Equipment
Hydraulic cylinders, gate hoists and related hydraulic machinery requiring controlled bearing movement under working loads.
Marine Equipment
Marine propulsion equipment and deck machinery operating under continuous mechanical loading and marine service conditions.
Industrial Transmission Equipment
Industrial transmission machinery and rotating assemblies where radial and thrust loads are present at the same bearing location.
OEM & Custom Options
Drawing-Based Production
Bearings can be manufactured according to customer drawings, including dimensions, tolerances, materials, clearances and surface requirements.
Sample-Based Replacement
Existing bearings or samples can be measured and evaluated for replacement production when original drawings are unavailable. Key dimensions and application conditions are reviewed before production.
Specification-Based Customization
For quotation and design evaluation, customers can provide bearing dimensions, radial and axial loads, shaft speed, lubrication method, operating temperature and required quantity.
Production Quantities
Sample, small-batch and production orders can be accepted. Production arrangements depend on bearing size, material configuration, machining requirements and order quantity.
Inspection & Quality Control
Dimensional Inspection
Bore diameter, outside diameter, bearing width and other critical dimensions are checked against the approved drawing and specified tolerances.
Clearance & Spherical Geometry
Radial and axial clearances, spherical surface dimensions and mating geometry are checked to confirm the required assembly fit.
Babbitt Lining Inspection
For Babbitt-lined bearings, the lining thickness, surface condition and bonding quality can be inspected according to the agreed requirements.
Material & Inspection Records
Base material and lining material can be verified against the specified requirements, with inspection reports or material documentation available when required.
FAQ
Q: What information is required for a quotation?
A: Provide the drawing or existing bearing sample when available. Key dimensions, radial and axial loads, shaft speed, lubrication, operating temperature and required quantity are also helpful.
Q: Can you manufacture a replacement bearing without the original drawing?
A: Yes. An existing bearing or sample can be measured and evaluated as the basis for replacement production, subject to dimensional and application review.
Q: Is a sample order available before bulk production?
A: Yes. Samples can be supplied for dimensional or application evaluation before batch production.
Q: What is the MOQ for custom spherical combination bearings?
A: Sample and small-batch orders can be accepted. MOQ depends on bearing size, material configuration and production requirements.
Q: What is the typical lead time?
A: Custom orders typically require several weeks after drawing confirmation and material approval. Actual lead time depends on bearing size, lining process, quantity and inspection requirements.
Q: Can packaging and shipping marks be customized?
A: Yes. Export packaging, product protection and shipping marks can be arranged according to customer or shipment requirements.
