Bronze Rubber Water Lubricated Propeller Shaft Bearings English Type 1″–3″

English Type 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 lining and are intended for hydro-lubricated operation.

The English Type range includes five configurations with shaft diameters from 1" to 3", external bearing diameters from 1 1/2" to 4" and overall lengths from 100 to 305 mm.

Bronze Housing and 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 hydro-lubricated marine propulsion systems. Water lubrication supports smooth shaft rotation and helps reduce friction and wear during operation.

English Type Design

The English Type series includes shaft bearings with imperial internal and external diameters. The manufacturer's catalogue also provides corresponding metric dimensions for both diameters.

The overall bearing length is specified in millimetres.

Bearing Dimensions

The technical drawing identifies three dimensions:

Ø A: Internal bearing diameter corresponding to the propeller shaft.
Ø B: External bearing diameter.
C: Overall bearing length.

Available Models and Dimensions

The following table lists all five English Type configurations according to the technical catalogue.
