Harken Sheaves come in 4 styles. Each style provide you with several sizes
and options that are right for your boat.
Harken 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.
Harken Big Boat sheaves are available for special applications
as well as for replacement sheaves in Big Boat blocks.
Made of Hard Lube-anodized, 6061-T6 aluminum,
sheaves feature Torlon® rollers to carry high radial
loads and carbon-black Delrin® balls to support
sideloads and provide UV protection. Select
sheaves based on load-carrying capability.
Harken High-load sheaves are offered as replacement parts or for use in
special applications. Their bearing system combines sideload-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.
Harken Narrow high-load sheaves in mastheads improve sail
handling, speed sail changes, and allow the use of smaller,
lighter halyard winches. Used in steering systems, these
sheaves return “feel” to wheel-steered boats. |
