WATER LUBRICATED BEARINGS


The water-lubricated bearing are made with an outer bearing of brass (OT63) or technoplastic polyamide
resin that has the advantage of neutralising electrolytic corrosion.

Boccole idrolubrificate per barche

The inside of the bearings are coated with black nitrile rubber with the following characteristics:

The bearings are lubricated with water that forms a very thin film between the shaft and rubber of the bearings, and reduces the coefficient of friction to very low values. Never run dry because a high temperature would immediately damage the bearing. Make sure the rubber does not come into contact with harmful substances, such as grease or lubricating oil. The circulation water contributes to evacuating the heat from the inner surface of the bearing, whose temperature must never exceed 50/60°C.

Therefore, it is necessary to:
