McKissick Wire Rope Sheave - Blk - Manila Rope - 1 in - 4-3/4 in GALVI

Product Description

The McKissick Old Style Block Sheave is a traditional-design replacement sheave engineered for use with manila rope and cable applications up to 1 inch in diameter. Constructed with a galvanized iron sheave, this component provides reliable corrosion resistance suited to marine, dock, and general industrial environments where exposure to moisture and the elements is a regular concern. The galvanized finish delivers a durable protective coating that extends service life in demanding outdoor and coastal conditions, making this sheave a practical choice for replacement and maintenance applications in existing old style block assemblies.

Featuring a 4-3/4 inch outside diameter sheave profile, this old style sheave is sized to provide smooth rope travel and reduce wear on manila rope during repeated load cycles. The self-lubricating bronze bushing bearing represents a significant maintenance advantage over standard plain bore or conventional bushing designs, as the self-lubricating properties of the bearing material reduce or eliminate the need for regular greasing in service. This is particularly beneficial in marine, fishing, and remote rigging applications where routine lubrication maintenance may be difficult or infrequent, while the bronze construction provides excellent corrosion resistance in saltwater and coastal environments.

This sheave is intended as a direct replacement component for McKissick old style block assemblies and is compatible with standard manila rope rigging configurations in the 1 inch diameter range. The combination of galvanized iron sheave construction and self-lubricating bronze bushing bearing makes this sheave well suited for marine, dock, fishing vessel, and general outdoor rigging applications where corrosion resistance and reduced maintenance are priorities. Always verify sheave compatibility with the specific block shell and pin dimensions before installation.
