Bronze Bearing Housing

The intermediate bearing incorporates a bronze cylindrical housing with an internally threaded connection. This construction allows the bearing to be connected to a compatible externally threaded stern tube.

The internal thread size depends on the propeller shaft diameter and selected article number.

Phenolic Bearing Bush

A phenolic bearing bush is fitted inside the bronze housing. It provides the internal bearing surface for the propeller shaft.

The bearing bush is an integral part of the intermediate bearing assembly and is specified for the corresponding shaft diameter.

Internal Threaded Connection

The available bearing models feature the following metric internal threads:

M40×1.5: For Ø25 mm propeller shafts.
M45×1.5: For Ø30 mm propeller shafts.
M50×1.5: For Ø35 mm propeller shafts.
M55×2: For Ø40 mm propeller shafts.
M60×2: For Ø45 mm propeller shafts.
M65×2: For Ø50 mm propeller shafts.

Each threaded connection must match the corresponding external thread of the stern tube installation.

Selection and Compatibility

Select the correct intermediate bearing according to the propeller shaft diameter and the internal thread size required for the stern tube connection.

The available configurations cover Ø25–50 mm propeller shafts with nominal stern tube sizes of Ø40–65 mm.

Before ordering, verify the propeller shaft diameter, stern tube connection dimensions and thread size of the existing installation.
