Plain Journal Fluid Film Bearing

Plain Journal Fluid Film Bearing is a high-performance sliding bearing for industrial rotating equipment. It forms a stable oil film through journal rotation, reducing direct contact between the shaft and bearing shell, thereby reducing friction, wear, and vibration.

Bearing Shell: Manufactured from high-strength metal materials, providing structural support and dimensional stability for the bearing, ensuring load-bearing capacity during long-term equipment operation.

Material Selection:
• Carbon Steel
• Cast Steel
• Bronze
• Stainless Steel
• Customized Materials

Babbitt Alloy Lining: Utilizing wear-resistant Babbitt alloy as the working layer, it possesses excellent friction-reducing and adaptability, reducing journal wear and protecting the shaft surface.

Main Functions:
• Reducing frictional loss
• Improving wear resistance
• Extending service life

Fluid Film Lubrication System: As the shaft rotates, it drives lubricating oil into the bearing shell clearance, forming a stable oil film to bear the load, reducing metal-to-metal contact and lowering operating temperature.

Stable Oil Film Lubrication, Improved Operational Reliability: Optimized bearing structure and lubrication clearance design enable the bearing to quickly form a stable oil film, reducing friction and operational vibration, and improving long-term equipment stability.

High Load Capacity, Suitable for Heavy-Duty Equipment: Utilizing a high-strength metal matrix and a rational structural design, the bearing's rigidity and load-bearing capacity are improved, meeting the continuous operation requirements of large rotating equipment.

Babbitt Metal Working Layer, Reduced Wear: High-performance Babbitt metal has excellent anti-friction and wear-resistant properties, reducing bearing wear, lowering equipment maintenance frequency, and extending service life.

Precision Machining, Guaranteed Installation Match: CNC machining and dimensional inspection control of key parameters ensure bearing fit accuracy and improve equipment operational smoothness.

Plain Journal Fluid Film Bearing is suitable for industrial equipment requiring stable shaft support, reducing operating wear and improving equipment reliability.

Main Applications:

• Turbines
• Compressors
• Motors
• Pumps
• Gearboxes
• Industrial Machinery
