A result of trickle-down from Grand Prix yacht racing Ronstan's range of Low Friction Rings provides an outstanding strength-to-weight solution where the absolute minimum friction of a ball bearing block is not required. That being said, the performance difference between well and poorly-executed versions of these simple products is marked. The basic appearance of the Ronstan Low Friction Ring range belies an exacting development process that investigated, tested, and delivered optimized performance in strength, weight, friction, line wear, and security.
Ronstan Low Friction Rings are machined from high-grade aluminum with a durable low-friction anodized coating and are available in three sizes to suit lines up to 14mm (9/16").
Low Friction rings can be used as a lightweight alternative to a block in some applications. They are best suited for systems requiring relatively small line deflection angles, or for high static loads.
The design achieves a nicely rounded internal profile for smooth control line trim under load, and a deep external groove to retain the rope securely within the large shoulders when spliced into a loop.
