The left photograph shows a water lubricated bearing specifically designed for the US Navy. Such bearings utilize AMBCO's proprietary compositions for the rubber bearing staves. The company has been designing and manufacturing staves for marine military and commercial applications for many years. The rubber staves are designed to give long service life while creating a low wear surface for the propeller shaft.

The right photograph is another view of a water lubricated bearing showing in more clear detail how the rubber staves are inserted into special grooves machined into the inner surface of the bearing.
