High-load sheaves are offered as replacement parts or for use in special applications. Their bearing system combines sideload-carrying balls with a Teflon® composite bushing to carry radial loads. While not as free-rolling as the standard Harken® ball/roller bearing system, this compact bearing system is extremely durable and perfect for carrying high loads in a restricted diameter. Installation requires clamping or securing inner race.

Use for masts, booms, deck organizers, through-the-transom running backstays.
