Rexnord FC3U255N Four Bolt Round Flange Block Ball Bearing

The Rexnord Link-Belt FC3U255N four-bolt round piloted flange block ball bearing is built for standard-duty service with a 3-7/16 in bore. Housed in cast iron for rigidity and durability, the unit uses a four-bolt round piloted flange for precise alignment and rigid mounting, while a setscrew locking mechanism secures the shaft to prevent slip under load. A single lip contact seal provides basic containment against contaminants and helps define a reliable, install-ready bearing block within the Link-Belt family. This FC3U255N model is selected when a robust, factory-aligned support is required for shafts in equipment where a 3-7/16 in bore and dependable rotation are priorities.
