Aqua Lube Water-Lubricated Rubber Propeller Shaft Bearings with Laminated Shell Ø25–50 mm

Aqua Lube Water-Lubricated Rubber Propeller Shaft Bearings are designed for marine propulsion shaft installations. Each bearing combines a laminated external shell with an internal rubber bearing lining intended for water-lubricated shaft operation.

The range includes seven dimensional configurations for shaft diameters from 25 to 50 mm, with external bearing diameters from 1 1/2" (38.1 mm) to 70 mm and overall lengths from 100 to 200 mm.

Laminated Outer Shell

Each bearing features a cylindrical laminated external housing that forms the mounting surface for installation in the corresponding marine stern tube or shaft support assembly.

The laminated housing surrounds the internal rubber bearing lining.

Water-Lubricated Rubber Lining

The internal bearing surface is manufactured from rubber and is intended for water-lubricated operation in marine propeller shaft systems.

The rubber lining provides the bearing surface for the rotating propeller shaft.

Marine Propeller Shaft Applications

These Aqua Lube bearings are intended for supporting and guiding propeller shafts in marine propulsion installations.

The range offers different combinations of internal diameter, external diameter and length to match the dimensions of the corresponding shaft installation.

Metric Shaft Diameters and External Dimensions

All internal shaft diameters are specified in millimetres. External bearing diameters are primarily metric, with one configuration featuring a nominal external diameter of 1 1/2".

Bearing Dimensions

Internal Diameter (ID): Diameter corresponding to the propeller shaft.
External Diameter (OD): Outside diameter of the laminated bearing housing.
Length (L): Overall bearing length.

Available Models and Dimensions

The following table lists all seven configurations according to the supplied Aqua Lube catalogue.

B145065	45 mm	65 mm	180 mm
B150070	50 mm	70 mm	200 mm

Alternative External Diameters for 25 mm Shafts

Two configurations are available for 25 mm propeller shafts:

B125112: External diameter 1 1/2" (38.1 mm), length 100 mm.
B125040: External diameter 40 mm, length 100 mm.

These versions provide alternative external mounting dimensions for the same shaft diameter.
