Product Description
Proven Performance in the FieldINDRON® self-lubricating bushings are extensively applied in marine rudder bearing and stern bearing systems on bulk carriers and working vessels. Proven through practical application, these bushings effectively replace traditional metal components in oil-lubricated ship systems. Specifically, the INDRON® bushings demonstrate outstanding performance as marine rudder bearings, offering enhanced durability and reduced maintenance needs.
When compared to other non-metallic rudder and stern bearings used in water-lubricated systems, INDRON® marine rudder bearings deliver a significantly longer service life. This not only improves the reliability of the marine rudder bearing system but also helps shipowners substantially lower operational and replacement costs.
