Common Concerns Answered
Will the journal bearing be sufficient for my high-performance needs compared to ball bearing blocks?
The journal bearing in the Harken Element series is engineered for robust performance and durability in its class. While ball bearings offer lower friction for extreme high-speed or low-load applications, the journal bearing provides a reliable and long-lasting solution for a wide range of typical sailing tasks, including mainsheets and jib sheets.
How does the aluminum construction hold up in harsh marine conditions compared to stainless steel?
The Element block features hardcoat-anodized forged aluminum sideplates, offering excellent corrosion resistance essential for saltwater environments. While stainless steel provides maximum hardness, the anodized aluminum is a proven, lighter, and more cost-effective material choice for this series, designed to withstand extended marine use.
Is the anodizing prone to wear under heavy use?
The hardcoat anodization provides a durable protective layer. Like most aluminum blocks subjected to consistent, very heavy loads over extended periods, some cosmetic wear of the anodizing is possible but does not typically compromise the structural integrity or functional performance of the block.
