McKissick Common Bore Sheave - 5/8 in Rope - 7/8 in

Product Description

The McKissick Roll-Forged Common Bore Sheave is a precision-manufactured wire rope sheave built for use in crane, hoist, and rigging block assemblies requiring accurate rope guidance and dependable load transfer. Featuring a 2 in outside diameter, 7/8 in inside diameter, and 1-1/4 in sheave width, this compact sheave is designed to accept wire rope up to 5/8 in diameter and integrates into standard bore shaft and pin arrangements via its common bore configuration. The roll-forged manufacturing process produces a denser, stronger grain structure compared to cast alternatives, resulting in a sheave with enhanced fatigue resistance and dimensional consistency suited to precision block assembly applications.

Manufactured from ductile iron, this sheave delivers superior toughness and impact resistance compared to standard cast iron, allowing it to absorb dynamic and shock loads without fracturing — a critical characteristic in active lifting and rigging systems. The machined rope groove is profiled to the wire rope diameter to promote even load distribution across the rope cross-section, reducing groove wear and extending both sheave and rope service life. The roll-forged process further refines the groove surface finish, contributing to smoother rope travel and reduced wear under repeated cycling.

The plain bore bearing configuration provides a straightforward, cost-effective solution for intermittent-duty or lower-speed applications where anti-friction bearings are not required. This sheave is suitable 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.
