Product Description

Self-Lubricating Fore & Aft Stern Tube Bearings

Reliable Marine Bearing Solution - Ideal Replacement for Thordon Bearings

Our self-lubricating stern tube bearings are engineered for marine applications, offering a high-performance, maintenance-free alternative to Thordon Bearings. Suitable for both fore and aft stern tube installations, these bearings ensure reliable shaft alignment, extended service life, and reduced operational costs.

Key Features:

1) Self-Lubricating Design. Operates without external lubrication systems - perfect for water-lubricated environments.

2) Replacement for Thordon Bearings.

3) Excellent Wear Resistance. Maintains dimensional stability and resists abrasion even under heavy loads and high shaft speeds.

4) Corrosion and Seawater Resistant. Specially formulated materials resist swelling, degradation, and marine biofouling.

5) Quiet, Vibration-Damping Operation. Reduces shaft noise and vibration, improving onboard comfort and equipment longevity.

6) Wide Temperature and Pressure Tolerance.Performs reliably across a broad range of marine operating conditions.

 

Typical Applications:

1) Fore & Aft Stern Tube Bearings

2) Rudder Bearings

3) Water-Lubricated Propeller Shaft Systems

4) Marine Pumps & Auxiliary Systems
