SIDEPOWER - SLEIPNER PROPELLER NUT TEN01055

Function and technical context

The Sidepower propeller nut - Sleipner TEN01055 is the fixing element that retains the propeller on the shaft of the auxiliary thruster, guaranteeing that the assembly rotates jointly and without play during the operation of the bow thruster or stern thruster. It works within the transverse auxiliary propulsion system, subjected to combined forces of torsion, vibration and continuous exposure to seawater. Its integrity is decisive for the correct functioning of the maneuvering thruster: a nut in poor condition can cause the propeller to progressively loosen, with the consequent risk of loss of thrust, damage to the shaft or even separation of the assembly during navigation. As it is a component manufactured according to the specifications of Sleipner Motor AS, a reference manufacturer in auxiliary propulsion systems under the Sidepower brand, this part ensures the appropriate fit and mechanical resistance for the propellers in this range.

When to replace this part?

The most common symptoms that indicate that the propeller nut should be checked or replaced are: unusual vibration or metallic noise during auxiliary thruster operation, loss of response or reduced thrust in docking maneuvers, and presence of noticeable play when inspecting the propeller assembly with the thruster stopped. It is recommended to inspect this nut during each seasonal maintenance, checking the tightness, the condition of the threads and possible galvanic corrosion caused by the marine environment. Replacing it preventively if there is any sign of wear prevents breakdowns at the most inopportune moment and protects higher-cost components such as the axle or the propeller itself.
