McKissick Common Bore Sheave - 1/2 in Rope - 4 in

Product Description

The McKissick Common Bore Sheave is a wire rope sheave designed for use in block and rigging assemblies where accurate rope guidance and reliable load transfer are required across a range of lifting applications. Featuring a 4 in outside diameter and a plain bore bearing configuration, this sheave is engineered 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, and general material handling environments. The common bore design allows for straightforward integration into existing block and sheave assemblies using standard shaft and pin arrangements.

Manufactured from powdered metal, this sheave is produced through a sintering process that compresses and fuses metal powder into a near-net-shape component with consistent density and dimensional accuracy. Powdered metal construction is well-suited for sheave applications where precise groove geometry, controlled porosity for lubrication retention, and cost-effective production are priorities. 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 plain bore bearing style provides a straightforward and economical solution for intermittent-duty or lower-speed applications where anti-friction bearings are not required. 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.
