This UCFU unit pairs a cast iron flange housing with an NTN ball insert bearing. It mounts rotating shafts to flat surfaces with fixed alignment and four-bolt fastening. The design suits power transmission equipment in industrial plants, agro-industry and maintenance workshops, and we supply it with technical guidance to match the right size.
The code breaks down as follows: U for a mounted unit, C for a four-bolt flange housing, F for the flange type, and the final U for the insert bearing. The number after the letters gives the shaft size in inches, and a trailing M denotes the sealing variant or housing configuration. Reading the code this way helps you order the exact unit without confusion.
Typical applications include belt conveyors, grain elevators, mixers, mills, centrifugal pumps and industrial fans. Flange mounting simplifies anchoring to sheet metal or structural steel, which is why these units appear in oilseed plants, feedlots, meat processing plants, quarries and metalworking facilities, as well as in road machinery, irrigation equipment and general power transmission systems. The cast iron housing stands up to dust, moisture and moderate loads, while the insert allows rotation with slight misalignment.
When selecting a unit, confirm the shaft diameter and the insert locking method: set screws, eccentric collar or adapter sleeve. Also review the sealing, since contact lip seal versions suit dusty or wet conditions. For installation, seat the flange on a flat, clean surface, tighten the four bolts in a cross pattern, and verify shaft alignment before start-up. The bearing is lubricated at the factory; in service, follow the manufacturer's relubrication interval.
UCFU mounted units interchange between brands in flange dimensions and shaft diameter when the series and insert type match. If you provide a part number from another brand or an unidentified part, we can identify the compatible equivalent. We supply the NTN line and help you confirm the unit will work correctly in your equipment.
To request a quote, send the complete part number on WhatsApp, such as UCFU-21⁄8M, or tell us the shaft size and flange type you need. We will reply promptly with the corresponding unit and the sealing options available.

Frequently asked questions
- What does UCFU stand for in an insert bearing housing?
- UCFU identifies a four-bolt flange mounted unit with an insert bearing. The first U means unit, C means flange, F means flange type, and the last U means the insert is present. The number that follows is the shaft diameter, usually in inches.
- How do I choose between a UCFU housing and another unit type?
- The UCFU fastens with four bolts to a flat surface, which provides more stability than a two-bolt housing. If the shaft is perpendicular to the structure, the UCFU is the usual choice. For parallel shaft mounting, other series are worth considering.
- What information do you need to quote the right housing?
- Send the full part number from the part or drawing, for example UCFU-21⁄8M. If you do not have it, provide the shaft diameter, the insert locking type and the working conditions. We will quote you on WhatsApp promptly.
