The NTN UCFU housing with insert bearing is a 4-bolt flange unit that combines an insert bearing with a cast housing. It is used to mount shafts on flat structures, with fixed alignment and simple mounting using four bolts. It is a common solution in transmission, conveying and process equipment where a robust, easy-to-maintain support is needed. MR Accesorios Industriales sells this line with technical advice so you can choose the right unit.
The UCFU series designation is read in parts: UCFU identifies the 4-bolt flange housing type with insert bearing; the number that follows, as in UCFU-2SM, indicates the shaft size and the sealing variant. The SM suffix corresponds to a specific seal in the series. To interpret each part number, note that the final letter can change depending on the seal type or additional protection. If you need to confirm the exact equivalent, send us the full part number via WhatsApp and we will quote it.
In Argentine industry, these housings appear in belt conveyors, chain elevators, mixers, mills, centrifugal pumps and bottling equipment. They are also found in food, chemical and aggregate processing plants, where mounting on sheet metal or a steel structure requires a firm, four-point flange. The UCFU series is one of the most requested for replacement and for building new machines, because it simplifies assembly and reduces intervention time.
To select the unit, check the shaft diameter, the load type (radial, axial or combined) and the environmental conditions. The SM seal protects against dust and moderate moisture; if there is frequent washing or fine particles, additional protection should be evaluated. During mounting, seat the flange on a flat, clean surface, tighten the four bolts in a cross pattern and check that the shaft turns without effort. The insert is lubricated from the factory; in service, follow the equipment maintenance plan.
NTN UCFU units are interchangeable with other brands that use the same flange standard and shaft diameter, provided the hole dimensions and center height match. That standardization makes replacement easier in plants with equipment from different origins. If you have another brand's part number or a worn part without identification, write to us via WhatsApp: we will tell you the compatible alternative or quote the exact size you need.
