Marine spare part and equipment for Shaft Bearing 80mm x 4" x 304,8mm.
Water-lubricated bearings featuring a metric inner diameter and an inch-based outer diameter. Designed with a brass shell, they accommodate rightward and leftward involute bearing rotations for propellers. The shaft is no longer constrained by a polygonal support, allowing it to be fully supported and guided around its circumference, which significantly reduces vibrations. This shaft rotation enhances a powerful pumping action in the involuted channels, leading to substantially increased fluid velocities and remarkable cooling, lubricating, and cleaning effects.
