How the Shaft Grounding System Works

The silver-plated ring provides a contact surface on the rotating propeller shaft. The graphite brush maintains sliding electrical contact with the ring, forming a conductive path to the grounding connection.

The system is intended for use as part of a marine shaft grounding arrangement. Installation and electrical connections must be compatible with the vessel's existing system.

Choosing the Correct Size

Select the kit according to the propeller shaft diameter. The available versions cover shaft sizes from 40 to 70 mm.

Check the shaft diameter, ring dimensions and available installation space before ordering.

Installation and Maintenance

Install the contact ring and brush holder according to the vessel's shaft grounding arrangement. Ensure that the graphite brush makes suitable contact with the silver-plated ring and that the grounding connection is correctly established.

Inspect the brush and contact surface periodically for wear, contamination and loss of contact.
