💡 What is a water-lubricated bearing used for in marine shafts and how does the water film work?

This handy explanation shows the role of the water wedge in protecting shafts and keeping things quiet on the water.

- The hydrodynamic grooves create a self-generated water film that reduces metal-to-metal contact. - The stainless steel body resists corrosion in saltwater, extending bearing life. - The water film helps dampen vibration and enables smoother operation at low shaft speeds. - This compact onboard accessory simplifies maintenance for boat owners and crews. ✝️
