Harken Megayacht blocks have an ultralight composite bearing system (ULC) that rides on a heat-treated stainless steel inner race to handle extremely high loads. Snap-fit Torlon® ball bearings carry thrust loads. Sideplates are mirror-polished stainless steel to reflect the traditional beauty of a classic yacht, or hardcoat-anodized 6061-T6 aluminum for strength and corrosion resistance—perfect for performance yachts.
Torlon is a registered trademark of Solvay Advanced Polymers L.L.C.
