Sealmaster FB-20 Flange Bracket Bearing 1-1/4 Bore 3-Bolt

Sealmaster FB-20 flange bracket bearing is a three-bolt, flange-mount ball bearing unit with a 1-1/4 in bore, designed for fixed (non-expansion) operation in light- to standard-duty machinery. The housing is cast iron, and the unit employs a setscrew locking arrangement with a felt labyrinth seal to help keep out contaminants. This FB-20 model is part of Sealmaster's FB Series flange-bearing lineup and is built for mounting in a three-bolt flange configuration, offering reliable shaft support in compact packages. Rated for a dynamic load of up to approximately 4,381 lb and a static load around 2,567 lb, it can reach speeds up to 5,450 rpm and operates over a temperature range from -20 to 220 degrees Fahrenheit. The combination of a fixed bearing, standard-duty designation, and a robust cast-iron housing makes it suitable for conveyors, machinery drives, and general line equipment where a ready-to-mount flange bearing is needed.
