McKissick Common Bore Sheave - 3/4 in Rope - 14 in

Product Description

The McKissick Common Bore Sheave is a heavy-duty wire rope sheave designed for use in crane, hoist, and rigging block assemblies where reliable rope guidance and load transfer are essential in medium to heavy lifting applications. Featuring a 14 in outside diameter and a plain bore bearing configuration, this sheave is engineered to accept wire rope up to 3/4 in diameter, making it well-suited for industrial, construction, marine, and oilfield environments where larger sheave diameters are required to reduce rope fatigue and extend service life. The common bore design allows for straightforward integration into existing block and sheave assemblies using standard shaft and pin arrangements.

Manufactured from cast iron, this sheave provides a cost-effective and proven solution for general-duty block assembly applications. Cast iron construction offers good compressive strength and wear resistance in standard lifting and rigging service conditions, and the larger 14 in outside diameter provides a favorable rope-to-sheave diameter ratio that reduces bending stress on the wire rope during operation. The machined rope groove is profiled to match the wire rope diameter, promoting even load distribution across the rope cross-section and reducing groove and rope wear over the service life of the assembly.

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 demanding lifting and rigging operations.
