Product Description

 

Product Description

Anti-corrosion Large-Diameter Intermediate Shaft Bearing Liner

The Anti-Corrosion Large-Diameter Intermediate Shaft Bearing Liner is a critical component in marine propulsion and heavy-duty shafting systems. Designed for longevity and reliability in harsh environments, it provides low-friction support for intermediate shafts while resisting seawater corrosion, wear, and pitting.

 

1. Superior Corrosion Resistance

• Material Options:

  • High-Performance Bronze Alloys (e.g., CuSn5Zn5Pb5, aluminum bronze)

  • Stainless Steel (316L/2205 Duplex) for extreme salinity conditions

  • Composite Polymers (e.g., Thordon, Orkot®) for non-metallic solutions

• Surface Treatments:

  • Electroplating (Ni-Cr, Zinc)

  • Anti-Galling Coatings (e.g., PTFE, MoS)

2. Optimized for Large-Diameter Shafts

• Diameter Range: Typically 200mm-1500mm+, customizable for vessel requirements.

• Precision Machining: Tight tolerances (IT7-IT8) for smooth shaft rotation.

• Split Design: Facilitates easy installation and maintenance without shaft disassembly.

3. Enhanced Durability in Marine Environments

• Resists:

  • Saltwater corrosion (pitting, crevice corrosion)

  • Cavitation erosion (in high-speed applications)

  • Microbial-induced corrosion (MIC) in stagnant water zones

4. Lubrication & Heat Management

• Grease Grooves/Oil Channels: Ensure even lubricant distribution.

• Thermal Stability: Maintains performance under variable loads (e.g., 0.5-5 MPa contact pressure).

• Marine Intermediate Shaft Bearings: Supports alignment in long shaft lines between engines and propellers.

• Offshore Rig Drivetrains: For jack-up rigs, FPSO vessels.

• Industrial Heavy Machinery: Pump shafts, hydroelectric turbines.
   

  Standards & Certifications

• Complies with ABS, DNV GL, LR, ISO 19916 (Shafting Systems).

• Material certifications: ASTM B584 (Bronze), ASTM A240 (Stainless Steel).
