The NTN Y-bearing insert unit pairs a cast iron housing with a self-aligning insert bearing in a 4-bolt flange configuration. It supports rotating shafts that must be fastened firmly to a flat surface, as seen in conveying equipment, agitators and transmission systems. MR Industrial Accessories supplies this line and helps you match the right part number to your application.
Reading the code starts with UCF, which denotes a 4-bolt flange housing with an insert bearing. The following digit tells you the size group: UCF2 covers metric shaft mountings in series 2, while UCF3 covers series 3 with higher capacity. A D1 suffix marks a construction variant of the insert. When a hyphen and three digits appear, as in UCF201-008D1 or UCF204-012D1, those digits give the shaft measurement in inches. Send the full part number and we quote exactly that reference.
Typical installations include belt conveyors, bucket elevators, mixers, centrifugal pumps, fans and packaging lines, in food, chemical, cement and metalworking plants. The 4-bolt flange mounts to sheet metal or angle iron structures, and the self-aligning insert compensates for minor shaft misalignment. MR Industrial Accessories supplies these units for replacement and for new projects.
Selection comes down to shaft diameter and load type: radial, axial or combined. Confirm that the bolt hole spacing of the flange matches your structure. The insert sealing determines suitability for dusty or humid conditions, with options such as a single lip seal or additional protection. The unit arrives lubricated, but in service check the grease condition and flange alignment before tightening the bolts. Mounting without stress avoids deformation and helps the bearing last.
For a replacement, the housing part number and shaft diameter are the essential data. UCF series from different brands generally share dimensions and hole patterns, though housing material or sealing type may differ. Cross-referencing by shaft diameter, bolt hole spacing and overall height is straightforward. Send those details on WhatsApp and we will point you to a compatible alternative or quote the exact part number on your equipment.
Whether your reference is UCF201D1, UCF204-012D1 or another in the line, MR Industrial Accessories quotes it promptly. Share the complete part number or your shaft and flange measurements, and we will reply with the option that fits your application.

Frequently asked questions
- What does the D1 suffix mean on a UCF housing?
- D1 indicates a construction variant of the insert bearing, typically tied to a specific sealing or tolerance. Flange dimensions and shaft diameter stay the same. Send the complete part number and we will quote that version.
- How do I choose between a UCF2 and a UCF3?
- UCF2 handles smaller shaft diameters, UCF3 larger shafts with higher load capacity. Your choice depends on shaft diameter and the radial and axial loads involved. Give us those measurements and we will recommend the right series.
- Are NTN UCF housings interchangeable with other brands?
- UCF series from different brands usually share flange dimensions and shaft diameters, so interchange is often possible. Housing material or sealing may differ. Send the original brand's part number and we will quote the NTN equivalent or the closest fit.
