How the Shaft Grounding System Works

The silver-plated contact ring fits around the propeller shaft. Two graphite brushes maintain sliding electrical contact with the ring as the shaft rotates.

The system provides a conductive path between the rotating shaft and the grounding connection when installed as part of the vessel's electrical grounding arrangement.

Choosing the Correct Size

Select the appropriate model according to the propeller shaft diameter. The available sizes range from 115 mm to 200 mm.

Models for shaft diameters of 115–127 mm have catalogue dimensions a = 3 mm and h = 50 mm. Models for diameters of 130–200 mm have dimensions a = 4 mm and h = 40 mm.

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

Installation and Maintenance

Fit the contact ring around the shaft and position the brush holder so both graphite brushes maintain contact with the ring. The grounding connection must be installed according to the vessel's electrical system requirements.

During routine maintenance, check the graphite brushes for wear and inspect the contact ring for contamination or damage.

Supply

One Tecnoseal propeller shaft grounding kit in the selected diameter, including one brush holder with two graphite brushes and one silver-plated contact ring.
