McKissick F-452 Trawl Block - 20 Ton - 16 in - Tapered Roller Bearing - Steel

Description du produit

The McKissick Series F-452 Trawl Block is a heavy-duty double rig configuration block engineered for commercial fishing and marine trawling applications where high load capacity, durability, and reliable performance in harsh saltwater environments are essential. Rated to a 20-ton working load capacity and featuring a 16-inch sheave outside diameter, the F-452 is built to handle the sustained dynamic loads generated during trawl wire deployment and retrieval operations. The double rig configuration accommodates two wire rope leads, making it well suited to paired trawl door and net rigging systems commonly used in demersal and pelagic fishing operations.

The Series F-452 is equipped with tapered roller bearings, a bearing type specifically suited to applications involving both radial and axial loads, providing superior load distribution and durability under the demanding conditions of commercial trawling. The steel sheave construction offers the strength and wear resistance required for sustained use with heavy wire rope under high-cycle operating conditions at sea. Together, the tapered roller bearing and steel sheave combination is designed to maximize service life and minimize maintenance requirements in the corrosive marine environment.

McKissick has a long-established presence in the commercial fishing and marine block industry, and the F-452 series reflects their engineering focus on performance and reliability in offshore and fishing vessel applications. Proper maintenance, including regular lubrication of bearings and inspection of sheave grooves and wire rope condition, is essential to maximizing the service life of trawl blocks operating in saltwater environments. All attachment hardware, swivels, and rigging components used in conjunction with this block should be rated to match or exceed the 20-ton working load limit.
