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

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 roller bearing configuration offers improved performance compared to plain bore or standard bushing designs, providing reduced friction and more efficient sheave rotation under load. Roller bearings are well suited to applications where the sheave experiences frequent cycling or sustained loads, delivering reliable performance with lower rotational resistance and supporting longer bearing service life compared to plain bushing alternatives in active rigging applications.

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 roller bearing provides a balance of corrosion resistance and improved rotational efficiency, making this sheave appropriate for marine, dock, fishing vessel, and general outdoor rigging applications where both durability and smooth rope handling are required. Always verify sheave compatibility with the specific block shell and pin dimensions before installation.
