Browning PBE920FX Pillow Block Bearing Four Bolt

The Browning PBE920FX four-bolt pillow block bearing is a heavy-duty, fixed (non-expansion) unit that houses a tapered roller bearing in a cast-iron housing. It employs a double collar mount lock and a single lip contact seal with uncoated surfaces, providing rugged support for rotating shafts. This PBE920FX family is offered in multiple bore sizes—2-7/16 in, 2-15/16 in, 3-3/16 in, 3-15/16 in, 4-1/2 in, and 4-15/16 in—to accommodate a wide range of shaft diameters. In a representative 4-1/2 in bore variant, the base-to-bore centerline is about 4.75 in and the base width about 4.625 in, with some housings finished in a powder-coated epoxy for durability. The bearing construction uses 52100 bearing steel for the rollers and races, ensuring high hardness and wear resistance in demanding applications.
