Phenolic Bearing Construction

The intermediate bearing is manufactured from phenolic material and features a cylindrical sleeve design for installation within the vessel's stern tube arrangement.

The bearing provides a contact surface for the propeller shaft as part of the inboard shaft support system.

Stern Tube Compatibility

Each bearing is specified for a particular combination of propeller shaft diameter and stern tube dimensions.

For Ø30 mm shafts, two stern tube options are available:

308032: Stern tube size 45 × 39 mm, bearing length 60 mm.
308032/N: Stern tube size 45 × 40 mm, bearing length 60 mm.

These configurations should be selected according to the actual tube dimensions.

Selection and Installation

Select the correct intermediate bearing according to three dimensions:

Propeller Shaft Diameter: 25, 30, 35 or 40 mm.
Stern Tube Size: The specified tube dimensions for the selected model.
Bearing Length: 60, 70, 80 or 100 mm.

Before ordering, measure the propeller shaft diameter, verify the stern tube dimensions and confirm the required bearing length.
