BARRAS LISAS Ø 40 L. 400 (ZN)

Function and technical context

The smooth bars with a diameter of 40 mm and a length of 400 mm with zinc (ZN) treatment are structural and guiding elements used in steering systems, rudders, control axles and transmission mechanisms in recreational and professional boats. Their zinc-plated finish gives them active protection against galvanic corrosion, especially in saltwater environments where ferrous metals are especially vulnerable. The dimensional precision of these bars is essential to guarantee the correct alignment of the coupled components, since any play or deviation can translate into loss of steering response or abnormal vibrations when driving. Its mechanical robustness ensures the transmission of forces without deformation under the usual navigation loads.

When to replace this part?

The most common signs of wear on zinc plated smooth bars include the appearance of surface rust or pitting in the zinc coating, visible deformations, excessive play in the coupling points or difficulty in sliding or rotating as smoothly as expected in the mechanism where they are installed. It is recommended to visually inspect these bars at each seasonal maintenance, paying special attention to the condition of the zinc plating and the straightness of the shaft, since a bent or corroded bar can compromise the safety and precision of the system on which it works. Preventively replacing a bar in poor condition avoids more costly breakdowns in the mechanical assembly and guarantees safe and predictable navigation.
