McKissick Powdered Metal Sheave - 1/4 in x 3 in - Self-Lubricating Bronze Bushing

Description du produit

 The McKissick Powdered Metal Sheave with self-lubricating bronze bushing bearing is a compact, lightweight wire rope sheave designed for lighter-duty lifting and rigging applications involving 1/4 in wire rope where a minimal assembly envelope, consistent dimensional accuracy, and low-maintenance bearing operation are the primary requirements. Powdered metal construction — produced through a sintering process that compresses and fuses metal powder into a precise, near-net-shape component — delivers consistent dimensional accuracy and is well suited to applications involving light loads and lower operating speeds. This sheave is appropriate for use in small block assemblies, light industrial rigging, utility hoisting systems, and maintenance applications operating within its rated capacity.

This sheave accommodates wire rope up to 1/4 in maximum cable diameter and features a 3 in outside diameter, making it a highly compact option well suited to small block assemblies and space-restricted rigging installations where a minimal footprint is essential. 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.
