Std collar anode D 20 mm - code: 5150020 - Motomarine

Collar anode STD D 20 mm Motomarine (code 5150020)

The’STD collar anode D 20 mm Motomarine, identified by code 5150020, is a spare part designed for common maintenance needs in the nautical field. Zinc collar anodes are used as consumable components in systems where sacrificial protection is useful, especially on metal parts exposed to the marine environment.

This version in collar format is suitable for installations on cylindrical elements with a nominal diameter D 20 mm, where the collar solution is practical for periodic replacement interventions and for storage or seasonal inspection operations.

Type: zinc collar anode

The product is an collar anode made of zinc, a material commonly used for sacrificial anodes in nautical applications. The “collar” geometry is designed to wrap around a cylindrical component and fix in position, making the installation neat and compact.

Nominal size D 20 mm

The wording D 20 mm identifies the nominal reference size of the collar. When choosing, it is important to verify that the diameter of the component on which it will be mounted is consistent with this indication, in order to achieve a correct fit and stable placement.

Maintenance on exposed components

The collar anodes are commonly used in maintenance to protect metal components subject to harsh environmental conditions. Their function is related to sacrificial protection: the anode is designed to consume over time, helping to preserve the parts to which it is associated.

Advantages of the collar solution

Practical installation and simplified replacement

The size collar is appreciated because it allows direct mounting on the component concerned, with a contained footprint and a neat arrangement. During maintenance, replacing the anode can be more immediate compared to solutions requiring brackets or dedicated supports, depending on the setup.

Solution consistent with scheduled maintenance

Anodes are consumable components: including them in a periodic inspection plan helps keep the system in proper condition. A collar anode of the correct size allows targeted intervention, maintaining the configuration provided by the installation.

Usage and operational notes

Dimensional check before purchase

Before proceeding with the order, it is advisable to verify the size correspondence D 20 mm with the diameter of the component on which the anode will be installed. In case of doubts, it is useful to compare the code 5150020 with the available technical documentation or with the previously mounted replacement.

Periodic inspection and replacement

As with all sacrificial anodes, it is good practice to carry out regular checks and replace the anode when it is worn out. The frequency of inspection depends on the conditions of use and the environment, but a check during normal maintenance activities (for example during storage) helps to prevent unplanned interventions.

Proper installation

To ensure correct operation, the anode must be installed securely and consistent with the setup. If you are not sure about the procedure or compatibility with your configuration, it is advisable to consult qualified personnel or your trusted maintenance technician.

FAQ – Frequently Asked Questions

What is a zinc collar anode used for?

A zinc collar anode is a consumable component used for sacrificial protection of exposed metal parts, typically in the nautical field. It is designed to wear out over time, helping to preserve the components it is associated with.

Is this anode suitable for propeller shafts?

Yes, the “collar anode” type is commonly used on shafts and cylindrical parts; the product description indicates it as a zinc collar anode for propeller shafts. It is still important to verify the correct size for your installation.

What does D 20 mm mean?

D 20 mm indicates the nominal size of the collar. Before purchasing, it is advisable to check that the diameter of the component on which the anode will be mounted is consistent with this measurement.

What is the product code of this Motomarine anode?

The supplier product code is 5150020. Using it as a reference helps in reordering and in comparison with the documentation or with the replacement already installed.

How often should a collar anode be replaced?

Anodes are subject to wear and should be checked periodically. Replacement is recommended when the anode is worn; the frequency depends on the conditions of use and the environment, so it is useful to include it in regular maintenance checks.
