McKissick TU-483 Snatch Block - 1-1/4 in - 60 Ton - 18 in - Roll-Forged

Product Description

The McKissick TU-483 Snatch Block is a high-capacity, heavy-duty single-sheave block engineered for the most demanding wire rope rigging applications in oilfield, offshore, marine, heavy construction, and industrial environments. Rated for a 60-ton working load limit, this block is built around an 18-inch outside diameter roll forged sheave supported by a tapered roller bearing with seal, providing exceptional load capacity, precise rope alignment, and long-term reliability under sustained heavy loads. The TU-483 series accommodates wire rope cable up to 1-1/4 inches in diameter.

The roll forged sheave construction delivers superior strength and fatigue resistance compared to cast sheave alternatives, making the TU-483 well suited for high-cycle operations and applications subject to shock loading or sustained tension in demanding field environments. The tapered roller bearing with seal provides high radial and axial load capacity while the integrated seal protects internal bearing components from contamination by dirt, water, mud, and debris, reducing maintenance intervals and extending operational life in harsh and remote field environments where routine servicing may be limited. The 18-inch sheave diameter provides a generous rope bend radius for the wire rope diameter range accommodated by this block, supporting rope longevity during high-capacity, high-cycle rigging operations while offering a more compact overall block profile than the 24-inch sheave variant in the same series.

The TU-483 is designed for use with heavy wire rope winches, cranes, and rigging systems where maximum working load capacity, roll forged sheave durability, and sealed bearing performance are all critical requirements. Its robust construction and sealed bearing system make it a dependable choice for oilfield, offshore, and heavy industrial operations where blocks are subjected to continuous use in demanding conditions with limited access to routine maintenance.
