Vetus BL50S1000 - Steel Stern Tube with Cutlass Bearing Ø 50 mm Length 1000 mm

Vetus BL50S1000 Steel Stern Tube with Cutlass Bearing Ø 50 mm, Length 1000 mm

The Vetus BL50S1000 is a high-quality steel stern tube engineered for water-lubricated propeller shaft systems using a 50 mm diameter shaft. This 1000 mm long tube includes a precision-machined cutlass bearing that provides stable support, reduced friction, and quiet operation under all load conditions. Manufactured from marine-grade steel, it ensures superior strength, resistance to corrosion, and excellent dimensional accuracy. Depending on the installation parameters—shaft diameter, length, and rotational speed— two or three cutlass bearings may be required to achieve optimal alignment and bearing support.

For installations requiring welded connections, optional reinforcement sleeves can be supplied to reduce distortion during welding, ensuring precise alignment and durability over the life of the vessel.
