The Marine Biaolong Bearing Stern Tube Bushing is a precision plain shaft bearing engineered for stern tube and intermediate shaft assemblies in vessel propulsion systems. It uses tin-based white metal, also known as Babbitt metal, conforming to ASTM B23 Grade for marine applications. The bushing provides low-friction support for propeller shafts under high radial loads and continuous exposure to marine environments, making it suitable for cargo vessels, tankers, and commercial fleets.
This bushing is manufactured from a multi-copolymer material compatible with both open and closed lubrication systems, tailored to the demands of stern tube, shaft, and rudder applications. The polymer composition adapts to varying lubricating mediums and operational fields, ensuring durability in harsh maritime conditions. Typical marine bearings of this class also incorporate tin-based alloys with a hardness range of 15 to 30 HB, standard for reducing wear in high-load scenarios.
Primarily sourced for new shipbuilding projects and aftersales replacements, this component is designed for bulk OEM orders and trading inquiries. It is widely used in applications where reliable shaft support and corrosion resistance are critical. Buyers typically confirm compatibility with existing propulsion systems, shaft diameters, and lubrication requirements before procurement. The bushing is supplied as a precision-machined component, ready for installation in marine propulsion assemblies.
