Aqua Lube Water-Lubricated Rubber Propeller Shaft Bearings with Metal Shell Ø25–80 mm

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

The range includes 12 dimensional configurations for shaft diameters from 25 to 80 mm, with different external diameters and bearing lengths.

Metallic Outer Shell

The bearings feature a cylindrical metallic external housing that provides the mounting surface for installation in the corresponding marine stern tube or shaft support assembly.

Water-Lubricated Rubber Lining

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

The rubber lining forms the contact 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.

Different combinations of internal diameter, external diameter and length are available to accommodate various shaft and stern tube dimensions.

Metric and Imperial External Diameters

The range features metric internal shaft diameters. External bearing diameters are primarily specified in millimetres, with two additional versions for 25 mm shafts using imperial external diameters of 1 1/4" and 1 1/2".

Bearing Dimensions

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