The V block delivers another breakthrough in Harken’s loop block series for Grand-Prix racers. Harken engineers have simplified the mechanics by combining the axial and thrust bearings into a single bearing set of V-shaped titanium rollers. The result is a strong, lightweight block that offers unmatched efficiency at high loads, while spinning freely at low loads for smooth easing in light air.
Bearing Design: Axial and thrust bearings are combined into a single bearing set of V-shaped titanium rollers.
Performance: Provides unmatched efficiency at high loads and spins freely at low loads for smooth easing in light air.
Materials: Features aluminum sideplates, titanium sheave, and captive titanium roller bearings.
Maintenance: Easy to disassemble for inspection and maintenance.
Sheave Capacity: Wide sheave accepts multiple lines for sail changes or a single, high-load larger line that requires a small deflection.
