Marine spare part and equipment for Brass Shaft Bearing 1"3/8 x 1"7/8 x 139,7 mm.
These water-lubricated bearings feature inner and outer diameters in inches. Constructed with a brass shell, they include a rightward involute bearing for propeller rotation and a leftward involute bearing for propeller rotation. The shaft is supported and guided around its entire circumference, rather than rotating in a polygonal support, effectively reducing vibrations. This rotation generates a powerful pumping action in the involuted channels, significantly increasing fluid velocity, and providing exceptional cooling, lubricating, and cleaning effects.
