McKissick Bar Steel Sheave - 3/8 in x 4 in - Bronze Bushing

Description du produit

The McKissick Bar Steel Sheave with bronze bushing bearing is a wire rope sheave engineered for crane, hoist, and rigging block applications where reliable rope guidance, enhanced bearing performance, and cost-effective construction are required in light duty lifting operations. Featuring a 4 in outside diameter and a bronze bushing bearing configuration, this sheave is designed to accept wire rope up to 3/8 in diameter, making it well-suited for light capacity crane, hoist, and rigging systems in construction, industrial, marine, and general material handling environments where a compact sheave solution with improved bearing performance is required. Bar steel construction is machined from solid bar stock, providing consistent material properties, good dimensional accuracy, and reliable performance in standard rigging block applications.

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 compact 4 in outside diameter makes this sheave well-suited for use in confined rigging arrangements or block assemblies where larger diameter sheaves cannot be accommodated, while the bronze bushing bearing provides enhanced performance over plain bore alternatives.

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 lifting and rigging operations.
