Allpa Bronze Propeller Shaft Strut with Neoprene Bearing for Ø25–60 mm Shafts

Allpa Bronze Propeller Shaft Strut with Neoprene Bearing for Ø25–60 mm Shafts

The Allpa Bronze Propeller Shaft Strut with Neoprene Bearing is a marine propeller shaft support assembly designed for installation on polyester and wood-epoxy boats. It combines a bronze support strut with an integrated neoprene bearing bush to support the rotating propeller shaft.

The strut features an elongated bronze mounting arm and a cylindrical bearing housing. The neoprene bearing bush is positioned within the housing to provide the bearing surface for the propeller shaft.

Seven configurations are available for shaft diameters of 25, 30, 35, 40, 45, 50 and 60 mm, with model-specific installation dimensions.

Technical Specifications

Available Models and Dimensions

The following dimensions correspond to the shaft diameter, B, D, G and H designations shown in the technical drawing. All linear dimensions are expressed in millimetres.

Bronze Strut Construction

The shaft strut consists of a bronze mounting arm connected to a cylindrical bearing housing. It is designed to provide support for the propeller shaft within the vessel's propulsion arrangement.

The mounting arm is intended for installation on a suitable hull structure. The technical drawing specifies the dimensions and angular arrangement of the strut.

Integrated Neoprene Bearing

The cylindrical housing incorporates a neoprene bearing bush that provides a bearing surface for the propeller shaft.

The bearing bush is matched to the specified shaft diameter, with configurations available from 25 to 60 mm.

Hull Installation

The Allpa bronze propeller shaft strut is intended for installation on polyester and wood-epoxy boats.

The technical drawing shows an inclined mounting arrangement with a 10° angle. Dimensions G and H identify the relevant strut lengths, while dimensions B and D relate to the bearing housing and mounting geometry.

Installation dimensions vary according to the selected propeller shaft size.

Selection and Compatibility

Select the appropriate bronze shaft strut according to the propeller shaft diameter and required installation dimensions.
