McKissick Bar Steel Sheave - 1/4 in x 4 in - Self-Lubricating Bronze Bushing

Product Description

The McKissick Bar Steel Sheave with self-lubricating bronze bushing bearing is a compact wire rope sheave designed for lifting and rigging applications involving 1/4 in wire rope where low-maintenance bearing operation, solid bar steel construction, and a space-efficient profile are required within a smaller assembly envelope. Bar steel construction provides dependable industrial-grade strength and durability suited to a wide range of rigging and hoisting applications operating within the sheave's rated capacity. This sheave is appropriate for use in small to medium block assemblies, light to moderate industrial rigging systems, and maintenance or utility hoisting applications where 1/4 in wire rope is specified.

This sheave accommodates wire rope up to 1/4 in maximum cable diameter and features a 4 in outside diameter, providing a functional rope-to-sheave diameter ratio for this rope size suited to compact block assemblies and space-restricted rigging installations. The self-lubricating bronze bushing bearing incorporates embedded lubricant within the bronze matrix that is released gradually at the bearing surface during operation, providing continuous lubrication without the need for regular external greasing. This feature makes the sheave particularly well suited to installations where maintenance access is limited, service intervals are infrequent, or simplified upkeep is preferred over standard bronze bushing arrangements that may require periodic re-lubrication.

McKissick is a recognized manufacturer of sheaves, blocks, and rigging hardware for the oil and gas, construction, marine, and industrial sectors. This sheave is intended for use as a replacement or component part within compatible McKissick block assemblies and rigging systems. All installations should comply with applicable load ratings, rigging standards, and inspection requirements to ensure safe and reliable operation throughout the service life of the assembly.
