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. Midrange sheaves come in either Delrin or aluminum for wire.
Wire sheaves are Hard Lube-anodized aluminum that ride on high-load composite bearings.
Ball bearings in the 1-1/2 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 Cruising ESP sheaves to handle high static loads from halyards and reef lines. Sheaves are carbon-black Delrin for UV protection and 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.
