The block’s wide throat allows passage of data cable terminals. The sheave’s durable, lightweight Nylatron® material has high mechanical stiffness, resists static electricity, and has excellent wear resistance. Plastic isolators and helicoils are used to minimize corrosion between aluminum and stainless steel. The Oceanic cable block is UNOLS compliant.
Delrin® roller bearings are housed in a center cage to keep them parallel for low-friction efficiency. The large diameter bearing cage reduces friction and spreads the load. Captive Torlon® ball bearings handle sideloads.
Large Diameter Sheave
The block’s open center helps move the center of gravity toward the shackle, improving the block’s ability to align with the load. The sheave’s groove detailing can be designed to suit specific data cable diameters.
The block is designed to work with an optional magnetic Hall Effect Sensor.
