McKissick Sheave - 3/4 in x 12 in - Plain Bore

Description du produit

 The McKissick Roll Forged Sheave with plain bore is a large-diameter, heavy-duty wire rope sheave designed for high-capacity lifting and rigging applications where robust roll forged construction and a flexible open bearing arrangement allow the end user to specify or supply their own pin, axle, or bushing to suit the requirements of a particular block assembly or maintenance application. Roll forging produces a sheave with refined grain flow aligned to the shape of the component, delivering excellent strength, toughness, and fatigue resistance well suited to the sustained dynamic loads encountered in large crane blocks and multi-part line rigging systems. This sheave is appropriate for use across the oil and gas, construction, marine, and industrial sectors where large-diameter sheaves are specified for high-capacity wire rope applications.

This sheave accommodates wire rope up to 3/4 in maximum cable diameter and features a 12 in outside diameter, providing a high rope-to-sheave diameter ratio that significantly reduces wire rope bending stress and extends rope service life in high-cycle or sustained-load applications. The plain bore configuration provides an unlined bore without a pre-installed bushing or rolling element bearing, offering maximum flexibility for integration into custom rigging builds, replacement of worn bore components, or assemblies where a specific bearing arrangement is dictated by the block design or operating environment. This makes the sheave a practical choice for maintenance operations, custom fabrication, and large-block rigging applications where the bearing solution is determined at the point of installation.

McKissick is a well-established manufacturer of sheaves, blocks, and rigging hardware serving the oil and gas, construction, marine, and industrial sectors. This sheave is suitable for use as a replacement or component part within compatible McKissick block assemblies and rigging systems. All installations should comply with applicable load ratings, rigging standards, and inspection requirements to ensure safe and reliable operation throughout the service life of the assembly.
