Involute Brass Bearings with Metric Inner and Outer ø

Water-lubricated bearings with metric inner and outer diameters.
Brass shell.

Right-hand involute (R) bearing for left-hand rotating propellers.
Left-hand involute (L) bearing for right-hand rotating propellers.
The shaft no longer rotates within a polygonal support, but is supported and guided along its entire circumference, thereby reducing vibrations. The shaft rotation generates a strong pumping effect within the helical channels, significantly increasing water velocity and improving cooling, lubrication, and channel cleaning.
