Common Concerns Answered
Is the journal bearing sufficient for high-performance sailing?
The journal bearing in this Harken Element block is robust and proven for its class, offering excellent durability for its price point. While ball bearings excel in extreme low-friction, high-speed scenarios, this block is designed for versatile and demanding everyday use where its strength and reliability are paramount.
How does the aluminum construction hold up in extreme marine environments?
The hardcoat-anodized forged aluminum sideplates provide significant corrosion resistance, making it suitable for saltwater. While extended, heavy use can eventually show wear on the anodizing, this is standard for aluminum hardware and does not compromise the structural integrity of the block.
Will the anodizing wear off quickly?
The hardcoat anodization is applied to enhance durability and corrosion resistance. While intense, prolonged use under heavy loads can lead to cosmetic wear on the anodizing, this is a common characteristic of aluminum components and does not typically impact the block's functional performance or lifespan.
