Product Introduction
Journal Thrust Bearing is a sliding bearing that integrates radial support and axial thrust bearing functions, and is mainly used in large, continuously operating rotating equipment.
Product Structure & Working Principle
Bearing Shell: Manufactured from high-strength metal materials, providing structural support and dimensional stability for the bearing.
Features: Bears operating loads; Maintains overall bearing rigidity; Improves long-term operational reliability.
Material Options: Carbon Steel, Cast Steel, Bronze, Stainless Steel, Customized Materials
Journal Bearing Section: Supports the rotating shaft with a lubricating oil film, reducing direct contact between the shaft and the bearing shell.
Functions: Bears radial loads; Stabilizes rotor operation; Reduces friction and vibration.
Key Factors: Bearing Clearance, Surface Finish, Load Capacity, Lubrication Design
Thrust Bearing Section: Bears axial thrust and restricts rotor axial movement.
Functions: Provides axial support; Maintains rotor positioning; Improves equipment operational stability.
Design Options: Fixed Pad, Tilting Pad, Customized Structure
Lubrication System: Forms a stable oil film through an oil lubrication structure, reducing friction and operating temperature rise.
Available Options: Oil Lubrication, Forced Lubrication, Lubrication Groove Design
Key Features
Combined Radial & Axial Load Capacity: Employs a combined radial and thrust structure, capable of simultaneously withstanding radial loads and axial thrust, reducing bearing configuration complexity and improving rotational system stability.
High Load Capacity: Utilizes a high-strength matrix and optimized load-bearing structure, adaptable to long-term heavy-load operating environments, reducing deformation and fatigue risks, and improving equipment reliability.
Stable Shaft Positioning: Controls rotor axial movement through a precision thrust structure, reducing abnormal wear caused by axial misalignment and ensuring stable equipment operation.
Low Friction & Wear: Through precision machining, reasonable clearance, and optimized lubrication, a stable oil film is formed, reducing frictional loss and maintenance requirements.
Long Service Life utilizes wear-resistant bearing materials and a reliable Babbitt alloy bonding process to improve wear resistance and make it suitable for continuous industrial operation.
Manufacturing Process
Raw Material Inspection: Perform material verification and composition testing on steel, copper alloys, and Babbitt metal to ensure materials meet requirements.
Precision Machining: Utilize CNC machining equipment to complete turning, milling, boring, and other processes to ensure dimensional accuracy and proper installation.
Babbitt Lining Process: Employ specialized casting and bonding processes to improve the reliability of the bond between the Babbitt metal and the substrate.
Final Inspection: Conduct dimensional, hardness, surface, and bonding quality inspections and provide relevant inspection documentation.
