Harken High Load Sheaves

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
