How does the ball bearing mechanism in Orbit Blocks enhance performance and reduce friction?
The ball bearing mechanism in Orbit Blocks enhances performance by utilizing a 2-stage bearing system, combining high-compression grade acetal ball bearings and a secondary full-contact bearing for minimum friction and maximum efficiency under high loads. This design ensures smooth operation, even in demanding sailing conditions, while the lightweight, fibre-reinforced composites in the block head contribute to achieving a superior strength-to-weight ratio. The orbital ball-bearing arrangement provides the largest possible bearing race diameter, optimizing load distribution and reducing wear.
In addition to their advanced bearing systems, Orbit Blocks™ are designed for versatility and strength. The lashing block configuration allows for secure attachment using lashing techniques, providing a lightweight and adaptable solution for various rigging applications. This design not only reduces overall weight but also offers sailors the flexibility to customize their setups according to specific needs.
What types of materials are used in the construction of ball bearing Orbit Blocks to ensure durability?
Ball bearing Orbit Blocks are constructed using all-composite reinforced polymer materials and glass fibre reinforced nylon to ensure durability and strength in marine environments. The high compression grade acetal ball bearings and orbital design reduce friction while enhancing load-bearing efficiency, making them ideal for high-stress sailing applications. These precision-engineered materials provide optimal performance and long-lasting reliability.
