McKissick Sheave - 3/8 in x 11-7/8 in - Bronze Bushing

Description du produit

The McKissick Bronze Bushing Sheave is a large-diameter wire rope sheave engineered for heavy-duty lifting and rigging applications where a generous rope-to-sheave diameter ratio is required to maximize wire rope service life and minimize fatigue under sustained or high-cycle loading. The 11-7/8 in outside diameter makes this sheave well suited to high-capacity block assemblies, large crane systems, and demanding industrial rigging configurations where rope bending stress must be kept within acceptable limits to preserve rope integrity over extended service periods. This sheave is a core component in heavy rigging systems used across the oil and gas, construction, marine, and industrial sectors.

This sheave accommodates wire rope up to 3/8 in maximum cable diameter and pairs that rope size with an 11-7/8 in outside diameter, providing an exceptionally high sheave-to-rope diameter ratio that significantly reduces wire rope fatigue and extends rope replacement intervals. The bronze bushing bearing delivers a proven, low-maintenance bearing solution with inherent lubricity and good corrosion resistance, performing reliably across a broad range of industrial conditions including intermittent use and environments where access for routine maintenance may be limited. Bronze bushing bearings are a widely specified option in heavy block and sheave assemblies throughout the rigging and lifting industry.

McKissick is a well-established manufacturer of sheaves, blocks, and rigging hardware serving the oil and gas, construction, marine, and industrial sectors. This sheave is suitable 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.
