The NTN Y-bearing insert unit is a 4-bolt flange unit that combines an insert bearing with a cast iron housing. It is used to mount rotating shafts on flat structures, with simple alignment and permanent lubrication. It is a compact solution for power transmission and conveying equipment in industrial plants, where the goal is to reduce mounting times and hold the shaft in position without complex machining. MR Accesorios Industriales sells this line with technical support.

The UCFA2 series designation is read in parts: UCFA identifies the 4-bolt flange unit, 2 indicates the insert bearing series and the number after the hyphen, when present, defines the shaft diameter in inches. The D1 suffix indicates a construction variant of the insert, usually with a contact seal and long-life lubricant. For example, UCFA201D1 and UCFA202-009D1 share the housing but differ in shaft diameter. These part numbers cover shaft sizes from 12 mm to 40 mm, depending on the series.

These units are used in belt conveyors, bucket elevators, mixers, blowers and packaging lines. In Argentina, they are common in food plants, cement plants, cold storage facilities and grain warehouses, where mounting on sheet metal or profile structures allows the shaft to be aligned with few adjustments. They are also chosen for irrigation equipment and road machinery, due to their weather resistance when the housing is painted cast iron.

To select the unit, check the shaft diameter and the bolt hole spacing of the housing. The insert comes lubricated and sealed from the factory; if the environment has dust or moisture, an additional seal is advisable. Mounting requires resting the flange on a flat surface, tightening the bolts in a cross pattern and checking that the shaft turns without effort. Alignment with the other support must be within the assembly tolerance to avoid axial loads.

NTN UCFA2 units are interchangeable with other brands that use the same 4-bolt flange nomenclature and shaft diameter. The key is to respect the bolt hole spacing and the insert diameter. If the original part number is not available, it can be replaced by an equivalent unit from another brand keeping those dimensions. MR Accesorios Industriales advises you to find the correct equivalent.
