McKissick Bar Steel Sheave - 3/8 in x 4-1/4 in - Self-Lubricating Bronze Bushing

Description du produit

The McKissick Bar Steel Sheave with self-lubricating bronze bushing bearing is a dependable wire rope sheave built for industrial lifting and rigging applications where low maintenance and consistent performance are priorities. Constructed from bar steel, this sheave provides solid strength and durability suitable for use in block and tackle assemblies, overhead crane systems, hoists, and general industrial rigging. Bar steel construction offers a reliable and cost-effective alternative to forged sheaves in applications where the loading and duty cycle align with its design parameters.

This sheave accommodates wire rope up to 3/8 in maximum cable diameter and features a 4-1/4 in outside diameter, maintaining an appropriate rope-to-sheave diameter ratio to support wire rope longevity and minimize fatigue during lifting and lowering cycles. The self-lubricating bronze bushing bearing is a key feature of this sheave, eliminating the need for regular greasing or external lubrication in many service conditions. The embedded lubricant within the bronze bushing is released gradually during operation, providing continuous lubrication at the bearing surface and reducing wear over the service life of the sheave. This makes the sheave particularly well suited to installations where access for routine maintenance is limited or infrequent.

McKissick has a long-standing reputation as a manufacturer of sheaves, blocks, and rigging components for the oil and gas, construction, marine, and industrial markets. This sheave is designed for use as a replacement or component part within compatible McKissick block assemblies and rigging hardware. Installations should comply with applicable load ratings, rigging standards, and inspection intervals to ensure safe and reliable operation throughout the service life of the assembly.
