所有 Zircon 滑轮都配有顺滑的柔性连接点。这可减轻紧固件重量，对系绳更友好，并使滑轮更好地与载荷路径对齐。
Harken Zircon Blocks
Size-for-size in our expanding range, Zircon blocks are the most efficient small boat blocks Harken has ever made. At the core of Zircon performance are industrial ceramic ball bearings mounted inside caged races. The cages keep these bearings apart so they don’t bunch up, touch, and stop each other. The result is a very free-running block with less energy lost to friction. Give an unrigged Zircon block a strong spin, and it spins for an incredibly long time. Zircon bearings are more than 700% stronger in compression than stainless bearings of the same size. So, they stay really smooth and won’t deform--within recommended load limits. More importantly, they don’t absorb as much energy before starting to roll. This becomes evident when you need to ease a sheet or multi-part control line in light air. You can react to very slight fluctuations in line load. When used expertly, that means better sail shape and more speed.
Zircon 的名称源自锆，它是元素周期表中的 #40 号金属元素。
Zircon 滑轮中使用的每颗陶瓷轴承球都非常坚硬、光滑且昂贵。因此，我们将该滑轮设计为仅使用 7 颗即可实现性能。
陶瓷轴承滚珠在同样由陶瓷制成的弧形内圈滚道中运行。该滚道需要由同类材料制成。没有它，陶瓷滚珠会从内部损坏滑轮。
白色内轴承座圈模制在黑色玻璃纤维增强滑轮材料内部。这是在皮沃基开发的一项新工艺。
