Bronze Rubber Water Lubricated Propeller Shaft Bearings Euro & Special Series Ø25–90 mm

Bronze Rubber Water Lubricated Propeller Shaft Bearings are designed to support and guide rotating propeller shafts in marine propulsion systems. The bearings combine a bronze outer housing with a rubber inner bearing lining and are intended for hydro-lubricated operation.

This product range combines the Euro Series and Special Series, offering 26 dimensional configurations for propeller shafts from 25 mm to 90 mm in diameter. The two series provide different external bearing diameters for corresponding shaft sizes, allowing selection according to the dimensions of the stern tube installation.

Bronze Housing with Rubber Bearing Lining

Each bearing features a cylindrical bronze outer housing and a rubber internal bearing surface. The bronze housing provides the supporting structure, while the rubber lining supports and guides the rotating propeller shaft.

Water-Lubricated Operation

The bearings are designed for water-lubricated marine propulsion systems. Water lubrication supports smooth shaft rotation and helps reduce friction and wear during operation.

Euro Series and Special Series

The combined range includes two dimensional series:

Euro Series: 13 configurations with shaft diameters from 25 to 90 mm, external diameters from 35 to 115 mm and overall lengths from 100 to 360 mm.
Special Series: 13 configurations with shaft diameters from 25 to 90 mm, external diameters from 40 to 110 mm and overall lengths from 100 to 360 mm.

The principal difference between these series is the external bearing diameter associated with each shaft size. Both series use metric dimensions.

Bearing Dimensions

The technical drawings identify three dimensions:

Ø A – Shaft Diameter: Internal bearing diameter corresponding to the propeller shaft.
Ø B – External Diameter: Outside diameter of the bearing housing.
C – Length: Overall length of the bearing.
