Standard and In-Stock Sheave Sizes
standard sheaves

RAND's standard sheaves are machined from extremely wear-resistant Ultra-High Molecular Weight (UHMW) polyethylene, offering reduced friction and longer life versus other materials. Click here for more information on UHMW and other available materials. RAND Sheaves are ideally suited for clean wire, fiber optic and all insulated wire products.

Call us today at 203-272-1352, fax your sheave requirements to 203-271-2650, or fill out our online form for a prompt, competitive quotation. Quantity discounts are available! Custom sheaves are also available on request!
