Big Boat sheaves are designed for special applications and serve as replacement parts for Big Boat blocks. These components are engineered to handle demanding nautical conditions with precision and durability.
Material Construction: The sheaves are manufactured from hardcoat-anodized, Ptfe-impregnated 6061-T6 aluminum, ensuring robust structural integrity and reduced friction.
Radial Load Handling: Torlon rollers are integrated into the design to effectively carry high radial loads during operation.
Sideload and UV Protection: Carbon-black Delrin balls support sideloads while providing essential protection against ultraviolet radiation.
