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

The designation UCFU 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, as in UCFU-17⁄8M, corresponds to the shaft size in inches; the final letter M indicates the sealing or housing configuration variant. Thus, UCFU-21⁄2M and UCFU-23⁄4M are units for 2½ and 2¾ inch shafts, respectively. Knowing this logic allows you to order 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, meatpacking plants, quarries and metallurgical facilities, where flange mounting makes anchoring to sheet metal or structural steel easier. 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 fastening type: there are versions with set screws, with eccentric collar or with adapter sleeve. Check the sealing: versions with contact lip seal are suitable for environments with dust or water. During mounting, rest 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 as regards flange dimensions and shaft diameter, as long as the series and insert type match. If you bring another brand's part number or an unidentified part, we will indicate the compatible equivalent. MR Accesorios Industriales sells the NTN line and advises you so that the unit works correctly in your equipment.
