Brass Rubber Water Lubricated Propeller Shaft Bearings Universal Series Ø25–90 mm
Universal Series Brass Rubber Water Lubricated Propeller Shaft Bearings are designed to provide support and guidance for rotating propeller shafts in marine propulsion installations. The bearings feature a brass outer housing with a rubber inner lining and are intended for water-lubricated operation.
The Universal Series includes eight configurations with shaft diameters from 25 to 90 mm, external bearing diameters from 38.10 to 114.30 mm and overall lengths from 100 to 360 mm.
Brass Housing and Rubber Bearing Lining
The bearings combine a brass outer housing with a rubber internal bearing surface. The metal housing provides the supporting structure, while the rubber lining supports the rotating propeller shaft.
Water-Lubricated Operation
These shaft bearings are designed for hydro-lubricated marine propulsion systems. Water lubrication supports smooth shaft rotation and helps reduce friction and wear during operation.
Universal Series Design
The Universal Series includes multiple dimensional configurations for different propeller shaft and stern tube sizes.
The internal bearing diameters are specified in metric measurements, while the external diameters are provided in both inches and millimetres.
Bearing Dimensions
The manufacturer's dimensional drawing identifies three measurements:
- 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 eight configurations according to the technical catalogue.
