Harken Self-Contained Sheaves

Harken Self-Contained Sheaves
Self-contained sheaves are designed for sailors to use in custom applications.

The Micro, Bullet and Big Bullet sheaves are Delrin with Delrin ball bearings. They are scored for rope. 16 mm AirBlock sheaves are Delrin and feature stainless ball bearings that ride in a grooved race. Mid-range sheaves come in either Delrin, or aluminum for wire.

Wire sheaves ride on high-load composite bearings. They are Hardkote-anodized aluminum with Teflon impregnation.

Ball bearings in the 11/2 in (38 mm) and 2 in (51 mm) sheaves minimize friction. The 1 in (25 mm) wire sheave uses low-friction washers for this purpose.

Two 160 sheaves make up the 161 dual sheave universal lead. Use this sheave to divert a line that must turn in either direction.

Use ESP sheaves to handle high static loads from halyards and reef lines. Sheaves are carbon-black Delrin for UV protection, and they turn on stainless steel spacers. Contained sideload ball bearings allow sheaves to spin freely when loads are released. Sheaves require a sideplate for the sideload balls to roll on.
