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. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eZircon 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.\u003c\/span\u003e\u003c\/p\u003e","products":[{"product_id":"harken-57mm-zircon-block","title":"Harken 57mm Zircon block","description":"\u003cp\u003e\u003cspan\u003eUse the Harken Zircon blocks for precision trimming.
