Construction and Bearing Arrangement

The steel stern tube is equipped with an outer Cutlass bearing at the propeller end. Slots in the tube facilitate bearing replacement without changing the complete stern tube.

Additional bearing support can be specified according to the required shaft arrangement:

Aft bearing: Standard Cutlass bearing at the propeller end.
Forward bearing (BR2): Optional second Cutlass bearing, supplied installed in the stern tube when ordered.
Intermediate bearing (BR3): Additional Cutlass bearing for installations requiring intermediate shaft support, supplied installed when ordered.

Optional Forward and Intermediate Cutlass Bearings

Shaft Diameter	Forward Bearing BR2	Intermediate Bearing BR3
25 mm	BR225	BR325S
30 mm	BR230	BR330S
35 mm	BR235	BR335S
40 mm	BR240	BR340S
45 mm	BR245	BR345S
50 mm	BR250	BR350S
60 mm	BR260	BR360S

Forward and intermediate bearings are optional components. The required bearing arrangement should be selected according to the propeller shaft installation.

Optional Welding Sleeves

Vetus steel stern tubes can be supplied with additional welding sleeves to reduce tube distortion during welding. This option must be specified when ordering.

Ordering and Selection

The following dimensions are required when ordering a Vetus steel stern tube assembly:

A – Propeller Shaft Length: Required shaft length in mm.
B – Stern Tube Length: Required steel stern tube length in mm.
D – Shaft Diameter: Propeller shaft diameter in mm.

When selecting the stern tube, also consider the outer tube diameter Q, minimum dimension K and the available installation space.

If additional forward or intermediate Cutlass bearings or welding sleeves are required, these must be specified with the order.
