Stern Tube Bearing · Shaft Line Equipment
Regular maintenance and inspection are crucial for ensuring the reliability and longevity of propulsion shaft systems, such as those protected by SKF Marine GmbH's Simplex Stern Tube Bushes. Designed to fit per propulsion shaft design specifications, these bushes are certified according to DNV standards. Common issues include wave bearing wear in coastal or shallow water operations due to sand and silt, seal leakage causing oil loss into the sea, propeller blade cavitation erosion, and wave leakage deviation leading to uneven lag wear. To address these potential failures, it is recommended to keep sealing elements and wear measurement tools on board, with a lead time of 4-8 weeks for spare parts. During docking, it is essential to measure bearing clearance and perform daily drain inspections on the seal, while conducting quarterly oil analysis and propeller inspections.
