Self-contained sheaves are designed for sailors to use in
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 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.
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.
