The NTN 4 Bolt Flange Bearing is used in industrial power transmission systems to support rotating shafts where mounting to a flat surface is required. Common applications include conveyors, fans, and material handling equipment. Its cast iron housing and set screw locking provide reliable shaft retention in moderate-load, general-purpose machinery.

This NTN bearing has a 3/4 in cylindrical bore, cast iron housing with set screw locking, and uses NLGI #3 equivalent lubricant. It measures 3 3/8 in length by 3 3/8 in height, with a 3/8 in mounting bolt size. The system of measurement is inch, and the manufacturer part number is UCFU-3/VBMT 330-PF 5015.
