Allpa Neoprene Propeller Shaft Bearing with Aluminum Housing for Ø25–50 mm Shafts

The Allpa Neoprene Propeller Shaft Bearing with Aluminum Housing is a cylindrical bearing sleeve designed for inboard marine propulsion systems. It combines a neoprene inner bearing lining with an aluminum outer casing to support the rotating propeller shaft.

The neoprene lining forms the internal bearing surface, while the aluminum housing provides the external cylindrical structure for installation within a compatible shaft bearing arrangement.

The range includes six metric configurations for propeller shaft diameters from 25 to 50 mm. The outside diameter and overall length vary according to the selected model.

Key Features

Neoprene inner lining: Internal bearing surface for the rotating propeller shaft.
Aluminum outer housing: Cylindrical metal casing surrounding the neoprene bearing lining.
Inboard application: Designed for marine propeller shaft bearing installations.
Metric dimensions: Shaft diameter, outer bearing diameter and length specified in millimetres.
Six shaft sizes: Available for Ø25, Ø30, Ø35, Ø40, Ø45 and Ø50 mm shafts.
Multiple outer diameters: From Ø35 to Ø66 mm.
Model-specific lengths: From 100 to 200 mm.

Neoprene Bearing Lining

The bearing features a neoprene inner lining that forms the bearing surface for the rotating propeller shaft.

The internal diameter corresponds to the specified shaft size, ranging from 25 to 50 mm.

Aluminum Outer Housing

The cylindrical outer housing is manufactured from aluminum and surrounds the neoprene bearing lining.

Its external diameter varies from 35 to 66 mm, depending on the shaft diameter and selected article number.

Bearing Dimensions

Each bearing is identified by three principal dimensions:

Propeller Shaft Diameter: Nominal internal bearing size, Ø25–50 mm.
Outer Bearing Diameter: Outside diameter of the aluminum housing, Ø35–66 mm.
Overall Length: Axial bearing length, 100–200 mm.

All three dimensions must be verified when selecting a replacement bearing.

Application

The Allpa neoprene propeller shaft bearing with aluminum housing is intended for inboard marine propulsion shaft support systems.

The bearing is selected to match the propeller shaft diameter and the mounting dimensions of the existing shaft support arrangement.

Selection and Compatibility

Select the correct bearing according to the shaft diameter, outside diameter and overall length.
