MG Duff ZSC Zinc Propeller Shaft Ring Anodes

MG Duff ZSC Zinc Propeller Shaft Ring Anodes – Ø25–40 mm

The MG Duff ZSC Zinc Propeller Shaft Anodes are ring-shaped sacrificial anodes designed to protect marine propeller shafts against galvanic corrosion. Manufactured from zinc, these anodes are available in four sizes to accommodate different shaft diameters.

The range includes ZSC25, ZSC30, ZSC35 and ZSC40, designed for propeller shafts measuring 25, 30, 35 and 40 mm respectively. All models have an overall length of 32 mm, while the external anode diameter varies between 63 and 76 mm.

The ZSC25 is specified with a steel core designed to help prevent loosening around the shaft.

Technical Specifications and Available Models

The MG Duff ZSC series includes four zinc shaft anodes with different shaft diameters. The shaft diameter and external anode diameter are separate specifications and should not be confused when selecting a replacement.

Construction and Design

The MG Duff ZSC anodes feature ring-shaped zinc bodies designed for installation around marine propeller shafts. The range provides different internal shaft sizes while maintaining a common overall length of 32 mm.

The ZSC25 features a steel core designed to prevent the anode from becoming loose around the shaft.

• Anode Material: Zinc.
• Body Shape: Ring.
• External Diameter: 63 or 76 mm, depending on the model.
• Overall Length: 32 mm for all four models.
• ZSC25 Steel Core: Designed to help prevent loosening around the shaft.

Dimensions and Shaft Compatibility

Each ZSC anode is designed for a specific propeller shaft diameter. The available models are:

• ZSC25: For Ø25 mm shafts, external anode diameter Ø63 mm, length 32 mm.
• ZSC30: For Ø30 mm shafts, external anode diameter Ø63 mm, length 32 mm.
• ZSC35: For Ø35 mm shafts, external anode diameter Ø76 mm, length 32 mm.
• ZSC40: For Ø40 mm shafts, external anode diameter Ø76 mm, length 32 mm.

The ZSC25 and ZSC30 share the same external dimensions but have different shaft diameters. Similarly, the ZSC35 and ZSC40 both have an external diameter of 76 mm but are intended for different shaft sizes.

When selecting a replacement anode, verify the shaft diameter, external anode diameter and available axial installation space.

Corrosion Protection

The zinc body functions as a sacrificial component, corroding preferentially to help protect electrically connected marine metal components against galvanic corrosion.

The MG Duff ZSC range is designed for propeller shaft corrosion protection. The ZSC25 is specifically identified for use in saltwater environments.
