MgDuff MGD Series Zinc Propeller Shaft Ring Anodes with Steel Core, 3/4"–2" Inch Sizes

MgDuff Zinc Propeller Shaft Ring Anodes with Steel Core – 3/4"–2" Inch Sizes, MGD Series

The MgDuff MGD Zinc Propeller Shaft Anode is a ring-shaped sacrificial anode designed to protect marine propeller shafts against corrosion in saltwater environments. Manufactured from zinc and equipped with a steel core, it provides corrosion protection for propeller shaft installations.

The steel core prevents the anode from becoming loose around the shaft. The range includes nine versions for imperial shaft diameters from 3/4" to 2", with different overall lengths and external diameters to accommodate the required shaft size.

Technical Specifications and Available Sizes

The MgDuff zinc shaft anode range includes nine variants with imperial shaft diameters. The overall anode length and external diameter are specified in millimetres.

Construction and Design

The MgDuff MGD shaft anode features a ring-shaped zinc body with an integrated steel core. The steel core is designed to prevent the anode from becoming loose around the propeller shaft.

• Zinc Body: Provides sacrificial corrosion protection for the propeller shaft.
• Steel Core: Prevents the anode from becoming loose around the shaft.
• Ring-Shaped Construction: Designed for installation around marine propeller shafts.
• Imperial Shaft Compatibility: Nine versions for shaft diameters from 3/4" to 2".

Dimensions and Shaft Compatibility

The anodes are available in three external dimension groups. Each group includes versions with different shaft openings corresponding to the specified imperial shaft diameters.

• 65 mm Length × 56 mm External Diameter: For 3/4", 7/8", 1" and 1 1/8" shafts.
• 78 mm Length × 70 mm External Diameter: For 1 1/4", 1 3/8" and 1 1/2" shafts.
• 100 mm Length × 85 mm External Diameter: For 1 3/4" and 2" shafts.

Select the anode according to the diameter of the propeller shaft. The overall anode length and external diameter should also be checked against the available installation space.

Corrosion Protection and Water Compatibility

The zinc anode functions as a sacrificial component, corroding preferentially to help protect the propeller shaft against corrosion.

The MgDuff MGD zinc shaft anodes are suitable for saltwater environments. Their steel core helps maintain the anode's position around the shaft, while the zinc body provides sacrificial corrosion protection.
