Construction & Materials
Journal Bearing Section
The journal section supports the rotating shaft through a lubricating oil film. Bearing clearance and surface finish are controlled according to the required operating conditions.
Thrust Bearing Section
The thrust section provides axial support and controls rotor movement. Fixed-pad and tilting-pad configurations are available, with the structure selected according to the bearing and equipment requirements.
Bearing Shell
The bearing shell provides the structural support for the bearing assembly. Available backing materials include carbon steel, cast steel, bronze and stainless steel, with other materials available for customized requirements.
Babbitt Lining
Steel-shell and Babbitt alloy constructions are available for fluid-film bearing applications. Bronze constructions can also be supplied according to the required bearing design.
Lubrication & Operating Conditions
Lubrication
Oil lubrication forms a supporting oil film between the rotating shaft and bearing surface, reducing direct metal-to-metal contact during operation. Forced lubrication and customized oil groove designs are available according to the bearing configuration.
Operating Conditions
Bearing speed, temperature, radial load, axial thrust load, shaft diameter, and lubrication conditions are evaluated during bearing selection and design.
Applications
Power Generation
Steam turbines, generators and water turbines requiring combined radial shaft support and axial thrust control.
Compressors & Pumps
Centrifugal compressors and large pump systems operating continuously under combined radial and axial loading conditions.
Heavy Industrial Equipment
Gearboxes, industrial transmission equipment and large rotating machinery.
OEM & Replacement Manufacturing
Drawing-Based Manufacturing
Journal Thrust Bearings can be manufactured from customer drawings, technical specifications, or existing bearing data. Production is based on approved dimensions, materials, tolerances, and operating requirements.
Replacement Bearings
Replacement units can be produced from original drawings, worn bearing samples, or dimensional measurement data for maintenance and spare-parts requirements.
Customized Configuration
Bearing size, clearance, lubrication grooves, and other structural features can be configured according to the existing equipment and approved technical requirements.
Quality Assurance
Dimensional & Tolerance Inspection
Bearing bore, outside diameter, bearing length, pad dimensions and other critical dimensions are inspected against approved drawings and specified tolerances.
Babbitt Lining Inspection
Babbitt lining thickness, surface condition and bonding to the backing material are inspected to identify defects or bonding irregularities.
Hardness Inspection
The hardness of specified bearing materials is tested to verify conformity with the required material specifications.
Final Visual Inspection
Machined surfaces, Babbitt-lined areas, oil grooves, mounting features and finished bearing surfaces are visually inspected before shipment.
FAQ
Q: What is the MOQ for a Journal Thrust Bearing?
A: MOQ depends on the bearing size, material, configuration, and production requirements. Single-unit orders can be evaluated for replacement, maintenance, or project requirements.
Q: Can you support prototype or trial orders?
A: Yes. Prototype and trial orders can be evaluated for new equipment development, replacement verification, or application testing.
Q: Can export packaging be provided?
A: Yes. Export packaging can be arranged according to the bearing size, shipping method, and customer requirements.
Q: What is the typical lead time?
A: Lead time depends on the bearing size, material, configuration, quantity, and drawing approval. The confirmed lead time is provided with the quotation.
Q: Can related spare parts be supplied with the bearing?
A: Yes. Related replacement components can be evaluated and supplied when specified in the purchase order.
Q: Can you support urgent replacement requirements?
A: Yes. Urgent orders can be evaluated based on bearing availability, configuration, quantity, and production schedule.
Q: Can you support long-term repeat orders?
A: Yes. Approved production specifications and drawings can be retained as the basis for repeat orders, subject to order confirmation.
