Sheaves

Big Boat and high-load sheaves are available for special applications as well as for replacement sheaves in Big Boat blocks. Made of Hard Lube-anodized, 6061-T6 aluminum, Big Boat sheaves feature Torlon® rollers to carry high radial loads and carbon-black Delrin® ball bearings to support sideloads and provide UV-protection. The high-load sheave bearing system combines sideload-carrying balls with a PTFE composite bushing to carry radial loads. While not as free-rolling as the standard Harken ball/roller bearing system, this compact bearing system is extremely durable and perfect for carrying high loads in a restricted diameter.
