McKissick Wire Rope Sheave - 1/2 in - 7-5/8 in - Plain Bore

Product Description

The McKissick ductile iron sheave with plain bore bearing provides a straightforward and cost-effective solution for wire rope rigging applications where simplicity of installation and solid sheave construction are the primary requirements. Ductile iron offers greater toughness and impact resistance compared to standard gray cast iron, making it a reliable sheave material for general industrial rigging service in construction, marine, oil and gas, and mining environments. The 7-5/8 in outside diameter sheave is designed to accept up to 1/2 in wire rope, supporting proper rope-to-sheave diameter ratios that minimize bending stress and contribute to extended wire rope service life.

The plain bore bearing configuration provides a simple bearing arrangement well suited for intermittent use, lower rope speeds, or installations where the sheave is mounted on a customer-supplied pin or shaft within a block or rigging assembly. This design eliminates the complexity of roller or bushing bearing systems, making it an economical choice for applications where operating conditions do not require enhanced rotational efficiency. The finish bore ensures dimensional accuracy for a proper and secure fit on standard rigging pins and shafts.

McKissick, a Crosby Group brand, supplies sheaves, blocks, and rigging hardware for demanding industrial applications across construction, marine, oil and gas, and mining sectors. This sheave is suitable for use in fixed or traveling block assemblies, crane and derrick systems, and other wire rope running rigging configurations. All installations should be performed, inspected, and maintained in accordance with applicable rigging standards and the manufacturer's recommendations to ensure safe and reliable operation.
