The UCFU flange housing with NTN insert bearing is a four-bolt flange unit that combines a cast iron housing with a ball insert bearing. It is used to mount rotating shafts on flat structures, with fixed alignment and four-bolt fastening. It is a compact, robust solution for power transmission equipment in industrial plants, agro-industry and maintenance workshops. MR Accesorios Industriales sells this line with technical advice to choose the right size.

The UCFU designation reads as follows: U indicates a mounted unit, C that it is a four-bolt flange housing, F the flange type and U the presence of the insert bearing. The number that follows corresponds to the shaft size in inches; the final letter M indicates the sealing variant or housing configuration. Understanding this logic lets you request the exact part number without ambiguity.

These housings are used in belt conveyors, grain elevators, mixers, mills, centrifugal pumps and industrial fans. In Argentina they are common in oilseed plants, feedlots, meat processing plants, quarries and metalworking facilities, where flange mounting makes it easier to anchor to sheet metal or structural steel. They are also used in road machinery, irrigation equipment and power transmission systems in general. The cast iron housing resists dust, moisture and moderate loads, and the insert allows rotation with slight misalignment.

To select the unit, check the shaft diameter and the insert locking type: there are versions with set screws, with an eccentric collar or with an adapter sleeve. Check the sealing: versions with a contact lip seal are suitable for dusty or wet environments. During installation, seat the flange on a flat, clean surface, tighten the four bolts in a cross pattern and check shaft alignment before start-up. Lubrication comes from the factory; in service, follow the manufacturer's recommendations for the relubrication interval.

UCFU mounted units are interchangeable between brands in terms of flange dimensions and shaft diameter, as long as the series and insert type match. If you bring us a part number from another brand or an unidentified part, we will tell you the compatible equivalent. MR Accesorios Industriales sells the NTN line and advises you so the unit works correctly in your equipment.
