Vetus ZINKAS30C Shaft Collar Zinc Anode Ø30 mm
The Vetus ZINKAS30C is a precision-engineered shaft collar zinc anode developed for effective cathodic protection of propeller shafts with a diameter of 30 mm. Shaft anodes operate in a high-flow environment and must remain securely fixed throughout their service life. The ZINKAS series incorporates an interlock system in both halves, ensuring perfect alignment and preventing the anode from loosening, even as material is gradually consumed.
This anode is manufactured from high-purity zinc in accordance with MIL-A-18001K specifications, providing predictable electrochemical performance in saltwater and brackish environments. Shaft anodes are not recommended for high-speed vessels, as they may generate turbulence around the propeller and, during erosion, can introduce imbalance. For such applications, a propeller nut with integrated anode is preferred. For standard propulsion systems, the ZINKAS30C offers reliable and long-term shaft protection.
Key Features
- Split shaft collar zinc anode for Ø30 mm shafts
- Manufactured to MIL-A-18001K specification
