McKissick Forged Steel Sheave - 5/8 in x 12 in - Bronze Bushing

Product Description

The McKissick Forged Steel Sheave with bronze bushing bearing is a heavy-duty wire rope sheave engineered for demanding crane, hoist, and rigging block applications where superior strength, durability, and enhanced bearing performance are required. Featuring a 12 in outside diameter and a bronze bushing bearing configuration, this sheave is designed to accept wire rope up to 5/8 in diameter, making it well-suited for medium to heavy lifting operations in construction, industrial, marine, and oilfield environments. Forged steel construction delivers a refined grain structure and significantly higher tensile and impact strength compared to cast alternatives, making it a preferred choice for high-cycle or heavy-load rigging systems.

The bronze bushing bearing provides superior lubrication retention and wear resistance compared to plain bore configurations, making this sheave well-suited for applications involving higher rotational speeds, continuous duty cycles, or environments where extended bearing service life is a priority. Bronze bushings offer excellent corrosion resistance, which is particularly advantageous in marine, offshore, and wet industrial environments where moisture and contaminants can accelerate wear in standard plain bore arrangements. The 12 in outside diameter provides an excellent rope-to-sheave diameter ratio that substantially reduces bending stress on the wire rope during operation, contributing to significantly extended rope service life and reduced maintenance intervals in demanding lifting applications.

The machined rope groove is precisely profiled to match the wire rope diameter, ensuring even load distribution across the rope cross-section and minimizing groove and rope wear throughout the service life of the assembly. This sheave is designed for use as a replacement or component part within McKissick and compatible wire rope block assemblies. Proper shaft fit, lubrication, and alignment are essential to achieving rated performance and maximizing service life in demanding industrial lifting and rigging operations.
