The NTN UCFA2 series covers 4-bolt flange units that pair an insert bearing with a cast iron housing. They let you support a rotating shaft on a flat surface with minimal alignment work, and the bearing arrives sealed and pre-lubricated. For maintenance and purchasing teams in conveying, mixing and air-handling equipment, these units simplify shaft mounting without machining the structure.

Reading the code helps you identify what you need. The letters UCFA point to the 4-bolt flange housing, the digit 2 refers to the insert bearing series, and any number after the hyphen gives the shaft diameter in inches. A D1 suffix marks a different insert build, typically with a contact seal and long-life grease. So UCFA201D1 and UCFA202-009D1 use the same housing but accept different shaft sizes. Across the series, shaft diameters run from 12 mm to 40 mm.

Typical applications include belt conveyors, bucket elevators, mixers, blowers and packaging lines. Food processing plants, cement operations, cold storage rooms and grain handling facilities often choose them because they bolt directly to sheet metal or profile structures, keeping shaft alignment simple. Irrigation systems and road machinery also use them, since a painted cast iron housing handles outdoor conditions well.

When selecting a unit, confirm two things: the shaft diameter and the bolt hole spacing on the housing. The insert is already lubricated and sealed at the factory. In dusty or damp areas, adding a supplementary seal is a reasonable precaution. During installation, set the flange on a flat surface, tighten the bolts in a cross pattern, and verify the shaft turns freely. Keep alignment with the opposite support within assembly tolerance to prevent axial loading.

NTN UCFA2 units can be swapped with other brands that follow the same 4-bolt flange naming and shaft diameter. What matters is matching the bolt hole spacing and the insert diameter. If you need a replacement, an equivalent unit from another maker will work as long as those dimensions line up. MR Industrial Accessories can help you identify the correct equivalent.
