McKissick Sheave - 7/16 in x 3 in - Bronze Bushing

Description du produit

The McKissick Powdered Metal Sheave with bronze bushing bearing is a wire rope sheave designed for use in block and rigging assemblies where accurate rope guidance, reliable load transfer, and enhanced bearing performance are required in light to medium duty lifting applications. Featuring a 3 in outside diameter and a bronze bushing bearing configuration, this sheave is engineered to accept wire rope up to 7/16 in diameter, making it well-suited for crane, hoist, and rigging systems in construction, industrial, and general material handling environments. Powdered metal construction is produced through a sintering process that compresses and fuses metal powder into a near-net-shape component with consistent density and dimensional accuracy, delivering precise groove geometry and cost-effective performance.

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 machined rope groove is profiled to match the wire rope diameter, promoting even load distribution across the rope cross-section and reducing wear on both the rope and the sheave groove during service.

The combination of powdered metal construction and bronze bushing bearing makes this sheave a practical and economical solution for applications requiring improved bearing performance without the cost of forged or cast iron alternatives. This sheave is designed to be used 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.
