McKissick Wire Rope Sheave - 1/2 in - 4-1/4 in - Bar Steel

Product Description

The McKissick Bar Steel Sheave with self-lubricating bronze bushing bearing is a wire rope sheave engineered for crane, hoist, and rigging block applications where reliable rope guidance, reduced maintenance requirements, and cost-effective construction are required in light to medium duty lifting operations. Featuring a 4-1/4 in outside diameter and a self-lubricating bronze bushing bearing configuration, this sheave is designed to accept wire rope up to 1/2 in diameter, making it well-suited for light to medium capacity crane, hoist, and rigging systems in construction, industrial, marine, and general material handling environments. 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 self-lubricating bronze bushing bearing is engineered to release lubricant continuously during operation, significantly reducing the need for external lubrication maintenance while providing consistent bearing performance over extended service intervals. This bearing type is particularly well-suited for applications in remote, elevated, or difficult-to-access rigging systems where routine lubrication is impractical, as well as environments where corrosion resistance and low-maintenance operation are priorities. The 4-1/4 in outside diameter provides a functional rope-to-sheave diameter ratio for a 1/2 in wire rope, and the combination of bar steel construction with self-lubricating bronze bushing bearing delivers a practical and economical solution for applications requiring improved bearing performance and reduced maintenance without the cost of forged or cast iron 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 and alignment are essential to achieving rated performance and maximizing service life in lifting and rigging operations.
