The Marine Biaolong Bearing Stern Tube Bearing is a water-lubricated bearing designed for propeller shaft support within a ship’s stern tube assembly. It features a cutless rubber lining that eliminates the need for oil lubrication and a shell made from brass or bronze for corrosion resistance. The bearing is supplied as a ready-made unit suitable for direct installation in both commercial and naval vessels. Its construction follows standard marine engineering practices for reliable low-friction operation.
Typical inner diameters range from 50 mm to 300 mm, covering most medium-size shaft applications. Load capacities commonly reach up to 250 kN, and the bearing can operate between -20 °C and +120 °C, matching the temperature envelope of most marine environments. Standard tolerances on the bore diameter are ±0.1 mm, and the rubber durometer is usually 70 ± 5 Shore A, providing adequate stiffness under water pressure. While the supplier does not list specific certifications, the design complies with recognised marine standards for water‑lubricated bearings.
Shipyards, repair facilities and naval maintenance depots are the primary customers for this component. The bearing can be supplied in flanged configurations with bolted studs, packed in crates or wooden pallets for secure overseas freight. Prospective buyers should confirm minimum order quantities, lead‑time estimates and preferred Incoterms with the supplier, as these details are not disclosed in the listing.

Importers should obtain the material data sheet for the rubber lining and the metallurgical certificate for the brass or bronze shell, confirming compliance with the required specifications. Verifying the bore size, load rating and operating temperature range against the vessel’s design documents is essential before finalising the order.
Typical freight terms include FOB Liaocheng or CIF to the destination port, with lead times of five to eight weeks after order confirmation, though exact schedules must be agreed with the supplier. Payment is usually arranged via T/T in advance or an irrevocable LC, and the buyer should specify the preferred Incoterm in the purchase contract.
A pre‑shipment inspection can verify dimension tolerances, durometer hardness and the integrity of the cut‑less rubber lining. Requesting an inspection report based on ASTM D2240 for hardness and a visual inspection checklist will help assure product quality before loading.
