Custom Mast & Boom Sheaves

If you need sheaves call me at 304 723-4553 or contact me.

I custom make them out of black acetal (see data sheet) so they are UV resistant and much stronger than cast plastic or Polyethylene sheaves.

Presently can make up to 6" diameter. Let us know the following details:

1/ Line diameter
2/ Measure the sheave diameter at the widest points. (Diameter)
3/ Measure the length between 2 sides. (Width)
4/ Use calipers and measure the diameter of the bolt / shaft or spacer that runs through the center hole. Do not measure the hole in the old sheave as it will be worn and probably incorrect.
5/ Let us know preferred style from the 3 below.
6/ Acetal is a low friction bushing material so bushings are not generally added.

Send the information and your details to us via the form here: http://dreamgreen.org/contact

Style #1 sheaves below which are the most common way we make them. The sides are cut back to reduce friction.
Style is used when cutting back the sides as in style 2 would leave a knife edge which would be weak and shorten the life span of the sheave.
Traditionally Bronze bushing were often used in sheaves however by using Acetal bushings are no longer required.

We carry Acetal material up to 6" diameter. Custom sheaves typically cost between $20 and $40, anchor roller sheaves are more.
All are custom made and normally ship within 24 hrs. Please contact to order.

Style #2 sheaves below with extended hub and cut back face which reduces side friction.
This style is used when the sheaves are thick enough to prevent a knife edge next to the groove.

Style #3: Flat sided.
These are shown with iGlide bushings but we no longer install them.
Generally made this way only on small diameter sheaves.
