The V™ block is the highest performing, most efficient block Harken has ever offered. Engineers chose extremely strong, extremely lightweight materials to build block components-3D molded carbon sideplates, titanium races, and captive titanium roller bearings. Then they combined the axial and thrust loads into a single bearing set of angled titanium rollers. The result is a 12% decrease in the number of unique components for an incredibly powerful, but simple lightweight block that surpasses any other block we've ever tested in efficiency at high loads, while spinning freely at low loads for smooth easing in light air.
"To eliminate lead times for customers, we decided to transform our highest performing Grand-Prix blocks. Where previously they have always been custom products, now they will be production products available on-the-shelf," says Mark Wiss, Director of New Business Development. "We increased the high-load efficiency and greatly improved low-load release responsiveness. We named it the V block because the angled inner races and sheave surfaces are 'V' shaped."
V blocks are easy to disassemble for inspection and maintenance. They are available in four (4) sizes dedicated to maximum working loads of 1500 kgf, 3000 kgf, 5000 kgf, 6500 kgf.
Sideplates are also available in anodized aluminum.
