A UCFX unit pairs an NSK insert bearing with a four-bolt flange housing made of cast iron. It holds a rotating shaft in place on equipment that needs straightforward mounting, correct alignment and support for combined loads. MR Industrial Accessories LLC supplies this line to plants and workshops across the United States and in several Latin American countries.
Reading the code helps you order the right unit. The letter U marks a mounted unit, C a four-bolt flange, F a cast iron housing, and X the medium-duty section variant. The D1 suffix covers sealing, while the closing characters identify shaft diameter and locking method. So UCFX05-013D1 and UCFX05-014D1 take the same housing with a different insert, and UCFX05D1 carries a standard insert. Give us the complete part number and we quote that exact unit.
Typical applications include conveyors, belts, elevators, mixers, fans and packaging lines, plus irrigation equipment and road machinery. Food plants, cement plants, tanneries and metalworking shops use them where the flange bolts to sheet metal or a steel structure and the bearing has to cope with dust and moisture.
Selection comes down to three things: shaft diameter, load type and the environment. The D1 sealing keeps contaminants out and lubricant in, which matters where washdowns are frequent. When mounting, sit the flange on a flat surface, tighten the four bolts in a cross pattern, and confirm the insert is aligned. Grease goes in through the fitting on the housing, using a lubricant matched to the working temperature.
UCFX units interchange with other brands that follow the same flange nomenclature and shaft diameter. When a part number does not line up, compare flange dimensions, shaft diameter and locking type instead. Our team can point you to a compatible alternative or quote the exact number you need.

Frequently asked questions
- What does UCFX indicate on a flanged bearing unit?
- It identifies a mounted four-bolt flange unit with a cast iron housing and a medium-duty section insert bearing. The D1 suffix and the closing numbers tell you the sealing and the shaft diameter. Send the full part number and we quote that unit.
- How do I pick the correct UCFX housing for my shaft?
- Start with shaft diameter, load type and working conditions. D1 sealing is important where dust or moisture is present. Mount the flange flat and tighten the bolts in a cross pattern. If anything is unclear, send the part number and we will help.
- Can UCFX housings replace units from other brands?
- Yes, provided the flange, shaft diameter and locking type match. The UCFX nomenclature is shared by several manufacturers. If the part number differs, compare dimensions or send us the model and we will suggest a compatible option.
