The Micro, Bullet, and Big Bullet sheaves are Delrin with Delrin® ball bearings. They are scored for rope. 16 mm sheaves are Delrin and feature stainless ball bearings that ride in a grooved race.
Ball bearings in the 38 mm (1 1/2") and 51 mm (2") sheaves minimize friction. The 25 mm (1") 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.
