High-Load Sheaves
High-load sheaves are offered as replacement parts or for use in special applications. Their bearing system combines side-load-carrying balls with a PTFE 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.
