Standard Cast Steel Sheaves
Features of the new designs include a selection of D/d ratios by sheave
diameter and wire rope size, a new shape for increased structural strength,
more weight for today’s higher and heavier overhaul requirements, and the
ability to alter wire groove details to allow compliance with certain industry
standards including API2C.
Miller Hi-Lift Blocks are furnished standard with new-design, cast
alloy steel sheaves and with cylindrical roller bearings up to 20”
diameter and with tapered roller bearings for 24” and larger
diameters.
Cast alloy steel sheaves are available in standard sizes from 8” to 36” in diameter and are listed in
the succeeding tables. Sheaves are available with bare bore, or with bearings or SAE 660 bronze
bushings. Stainless steel versions of the sheaves in the following tables are also available. Available
with grease fitting by request, lubrication through the sheave pin is recommended. Standard
groove angle is 30° minimum and groove radii meet API requirements
