Harken High-load sheaves are offered as replacement parts
or for use in special applications. Their bearing system combines sideload-carrying
balls with a PTFE composite bushing to carry radial loads. While not
as free-rolling as the standard Harken® ball/roller bearing system,
compact bearing system is extremely durable and perfect for carrying
high loads in a restricted diameter.
Installation requires clamping or securing inner race.
On the 1734 Harken High-load-sheaves, the wide tulip sheave
allows wider range of line entry angles.
