McKissick Forged Steel Sheave - 3/8 in x 4-7/8 in - Tapered Bearing

Description du produit

The McKissick Forged Steel Sheave is a heavy-duty wire rope sheave engineered for demanding lifting and rigging applications where strength, precision, and long service life are essential. Constructed with a forged steel sheave body, this unit delivers superior resistance to impact and wear compared to cast alternatives, making it well suited for use in overhead cranes, hoists, block and tackle assemblies, and other high-cycle rigging systems. The forged construction ensures consistent grain structure throughout the sheave, providing reliable performance under sustained dynamic loads.

This sheave accommodates wire rope up to 3/8 in maximum cable diameter and features a 4-7/8 in outside diameter sheave, providing the correct rope-to-sheave diameter ratio necessary to minimize wire rope fatigue and extend rope service life. The tapered bearing design delivers smooth rotation under load, reduces friction, and supports accurate load control during lifting and lowering operations. Tapered bearings are particularly well suited to applications involving both radial and axial loading, offering greater durability than standard sleeve or ball bearing configurations in heavy industrial environments.

McKissick is a recognized leader in the design and manufacture of blocks, sheaves, and rigging hardware for the oil and gas, construction, marine, and industrial sectors. This sheave is designed to integrate with McKissick block assemblies and compatible rigging hardware, and is available as a replacement or component part for maintenance and repair of existing systems. Proper installation, inspection, and load rating compliance should be observed in accordance with applicable rigging standards.
