Std collar anode D 22 mm - code: 5150022 - Motomarine

STD collar anode D 22 mm Motomarine (code 5150022)

The’STD collar anode D 22 mm Motomarine, identified by code 5150022, is a spare part designed for use in the nautical field and for maintenance activities on propulsion components. It is a zinc collar anode, a commonly used solution for the protection of submerged metal parts, especially near transmission components such as propeller shafts.

Type: collar anode (STD)

The product is an collar anode (indication STD), a configuration designed to be installed “around” a cylindrical element. This geometry is typical when you want to position the anode stably and close to the part to be protected, maintaining a compact size and practical mounting during storage or routine maintenance operations.

Material: zinc

The anode is made of zinc, a material widely used in the nautical sector for sacrificial anodes. The choice of material is a key aspect in managing galvanic corrosion: therefore, when purchasing and replacing, it is important to maintain consistency with what is specified by the system and the maintenance habits of the boat.

Nominal diameter: D 22 mm

The indicated measurement is D 22 mm. This data is essential for identifying the spare part: in collar anodes, the diameter is the main reference for the correct match with the element on which the anode must be mounted.

Typical applications

Use on propeller shafts

Recommended for propeller shafts. In such applications, the collar anode is positioned near the area to be protected, helping to manage corrosion that may affect metallic components immersed and electrically connected to each other.

When replacement can be useful

The replacement of a collar anode is generally considered when the anode is worn or no longer in suitable condition. In practice, during inspection, the state of the material and the overall integrity of the component are evaluated. In case of doubts about suitability, it is good practice to compare the replacement with the original (shape and diameter) and refer to the product code.

Collar shape: targeted installation

The collar shape allows positioning directly on the cylindrical element involved, with a practical approach for those performing maintenance on transmissions and propulsion components. It is a common solution because it allows placing the anode in a functional point without having to use brackets or external supports (when the installation is indeed planned as collar).

Consistency with scheduled maintenance

Integrating a zinc collar anode into the maintenance plan helps maintain an orderly and repeatable approach: visual inspection, measurement check, replacement when necessary. Even without going into specific plant details (which vary from boat to boat), the logic of managing the replacement remains the same: choose the correct size and maintain compatibility with what is provided by the existing installation.

Measurement check before purchase

Before proceeding with the order, verify that the requested size is actually D 22 mm. In case of replacement, the simplest method is to compare the nominal diameter of the removed anode or measure the element on which the anode must be installed, ensuring that the size matches.

Periodic check and inspection

Anodes are components subject to wear: for this reason, it is advisable to include them in periodic checks, especially during hauling, storage, or interventions on the engine and shaft line. Regular checks help understand when it is appropriate to intervene and plan the replacement along with other spare parts.

Installation and best practices

Installation must be carried out consistently with the boat's configuration and the adopted maintenance procedures. In general, it is important that the component is correctly mounted and that the installation area is suitable. If you are not sure about the correspondence or the mounting method, it is preferable to consult a technician or someone who regularly handles the plant's maintenance.
