McKissick F-452 Trawl Block - 22 Ton - 22 in - Tapered Roller Bearing - Steel

Product Description

The McKissick F-452 Trawl Block in the Double Rig configuration is a heavy-duty commercial fishing block engineered for the demanding conditions of offshore trawl fishing operations requiring a 22 Ton working load capacity. Built around a 22-inch outside diameter steel sheave, this block is designed to handle the large-diameter, high-tension wire ropes and cables used in deep-sea trawling, providing the rope capacity and structural strength necessary for sustained operation in harsh marine environments. The double rig configuration allows the block to accommodate two rope or wire runs simultaneously, supporting the paired trawl wire arrangements common in commercial bottom and mid-water trawl fishing operations.

The F-452 is equipped with tapered roller bearings that provide efficient load distribution across both radial and axial forces generated during active trawling. Tapered roller bearings are well suited to the combined loading conditions inherent in trawl block applications, where the block must handle both the direct pull of the trawl wire and lateral forces introduced by vessel motion and wire fleet angles. The steel sheave construction delivers the durability and wear resistance required for continuous operation with wire rope under the abrasive and corrosive conditions of the marine environment.

Designed specifically for commercial fishing vessel applications, the McKissick F-452 Double Rig Trawl Block is built to withstand the repetitive high-load cycles of active fishing operations, including net setting, towing, and hauling. Its robust construction and proven McKissick trawl block design make it a reliable choice for fishing vessel operators requiring dependable performance in North Atlantic, Pacific, and other demanding offshore fishing environments. Always verify working load limits, wire rope compatibility, and mounting configuration prior to installation and use.
