Bronze Shaft Strut Construction

The shaft strut consists of a bronze support arm, a straight mounting flange and a cylindrical bearing housing with a neoprene bearing bush.

The mounting flange provides a connection to the vessel's supporting structure, while the bearing housing supports the propeller shaft.

Neoprene Shaft Bearing

The strut includes a neoprene bearing bush fitted inside the bronze bearing housing.

The bearing bush is selected according to the propeller shaft diameter. Seven configurations are available for shafts from 25 to 60 mm.

Mounting Flange and Standard Angle

The standard configuration is supplied with a straight mounting flange and a 15° longitudinal bearing inclination.

The installation geometry is determined by the shaft inclination and the mounting arrangement of the vessel.

Custom Installation Geometry

For orders of multiple units, the shaft strut can be manufactured according to specified installation dimensions.

The variable dimensions are:

H: Height of the support strut.
α: Longitudinal inclination of the bearing housing.
β: Transverse inclination of the support strut.

For Ø25–50 mm shaft configurations, the longitudinal inclination range is 9–16° and the transverse inclination range is 0–22°.

For the Ø60 mm configuration, the longitudinal inclination range is 6–15° and the transverse inclination range is 0–20°.

Selection and Compatibility

Select the correct Allpa bronze shaft strut according to the propeller shaft diameter and required mounting geometry.

468125: Ø25 mm shaft, maximum support height 180 mm.
468130: Ø30 mm shaft, maximum support height 200 mm.
468135: Ø35 mm shaft, maximum support height 230 mm.
468140: Ø40 mm shaft, maximum support height 260 mm.
468145: Ø45 mm shaft, maximum support height 300 mm.
468150: Ø50 mm shaft, maximum support height 350 mm.
468160: Ø60 mm shaft, maximum support height 400 mm.

Before ordering, verify the propeller shaft diameter, shaft inclination, bearing housing dimensions, mounting plate geometry and required support height.
