Stern Shaft Sealing Device Brass Bushing

Core advantages:

1. Special performance for marine environment

Super corrosion resistance: Passed the salt spray test, resists the erosion of seawater, microorganisms and marine atmosphere, and has a long service life.

Anti-biological attachment: Special surface treatment can reduce the attachment of marine organisms such as barnacles and algae, and reduce friction resistance.

Electrolytic compatibility: Compatible with the hull cathodic protection system to avoid electrochemical corrosion.

2. Key guarantee of the sealing system

Precision matching: The inner hole processing has high precision to ensure concentricity with the stern shaft and reduce abnormal wear of the sealing ring.

Self-lubricating design: optional graphite inlay or oil-containing microporous structure to maintain long-term lubrication under conditions where frequent oil replenishment is not possible.

Anti-sand wear: grooved oil channel design can store grease to prevent sand from invading the sealing area (especially suitable for dredgers and tugboats).

3. High reliability and safety

Redundant strength: meets the heavy-load requirements of large cargo ship shaft systems.

Anti-loosening structure: bolt holes or pin grooves can be processed on the flange end face to eliminate the risk of axial movement.
