McKissick Forged Steel Sheave - 3/4 in x 12 in - Roller Bearing

Product Description

The McKissick Forged Steel Sheave with roller bearing is a large-diameter, heavy-duty wire rope sheave engineered for demanding lifting and rigging applications where high-efficiency rotation, superior load capacity, and extended service life under sustained or high-cycle loading are required. The forged steel sheave body provides exceptional strength, toughness, and resistance to impact, with a consistent grain structure achieved through the forging process that ensures reliable integrity under the dynamic and shock loads encountered in high-capacity rigging systems. This sheave is well suited for use in large crane blocks, multi-part line rigging systems, and demanding industrial configurations across the oil and gas, construction, marine, and industrial sectors.

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 roller bearing configuration delivers low-friction, high-efficiency rotation under heavy radial loads, making it an excellent choice for high-speed or high-cycle applications where bearing performance, reduced heat generation, and operational efficiency are critical. Roller bearings are widely specified in large industrial sheave applications for their ability to handle significant radial loads with minimal energy loss and reduced maintenance requirements compared to bushing-type bearing configurations, making them the preferred choice in demanding, continuous-duty rigging systems.

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.
