Narrow Sheaves in mastheads improve sail handling, speed sail changes, and allow the use of smaller, lighter halyard winches. Extensively used in steering systems, these sheaves return movement to wheel-steered boats. Sheaves combine sideload-carrying balls with a composite bushing for radial loads. These durable sheaves are designed of best grade materials and are well-suited for masthead and steering installations. Installation requires clamping or securing inner race. Besides, the sheaves are stringently checked on various parameters. Moreover, these Narrow Sheaves can be availed from us in various specifications.
