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.
Masts, Booms, Deck organizers and Through-the-transom running backstays.
