The NTN UCFL housing with insert bearing is a two-bolt flange unit that pairs a cast iron housing with an insert ball bearing. It mounts rotating shafts to flat surfaces, providing fixed alignment and straightforward installation. MR Industrial Accessories LLC supplies this line to customers across the United States and in several Latin American countries for transmission and conveying equipment.
The UCFL code breaks down into useful information. The UCFL prefix denotes a two-bolt flange housing with an insert bearing. The number that follows indicates shaft size, and the D1 suffix signals a particular sealing and insert configuration. For instance, UCFL201D1 fits a 12 mm shaft, while UCFL204-012D1 pairs the metric size with its inch equivalent. The UCFL2 and UCFL3 series cover a range of shaft diameters and load capacities.
Typical applications include conveyors, belts, elevators, mixers, fans and packaging lines. The gray cast iron housing handles weather exposure, and the insert ball bearing with nitrile seals suits dusty or moderately moist environments. Mounting on sheet metal or structural profiles is common where a two-bolt flange is required.
When selecting a housing, consider shaft diameter, load type (radial, axial or combined) and operating conditions. The insert arrives pre-lubricated and generally needs no additional maintenance. During installation, ensure the support surface is flat and clean, and tighten the flange bolts properly to prevent vibration. Aligning multiple housings is essential so the bearing does not face lateral forces.
NTN UCFL housings interchange with other brands that follow the same dimensional nomenclature. If you have a part number from another manufacturer or an unidentified part, MR can identify the compatible equivalent. Before replacing, confirm the hole thread and center distance, especially on imported equipment.

Frequently asked questions
- What does the D1 suffix mean on UCFL housings?
- The D1 suffix indicates a specific insert variant, typically related to sealing type and internal configuration. It does not affect flange mounting dimensions, but it does influence service conditions. If unsure, send the complete part number and we will advise.
- How do I choose the right UCFL housing for my shaft?
- You need the shaft diameter and load type. The UCFL2 series covers smaller shafts and UCFL3 larger ones. Environment and mounting position also matter. With that information we can specify the exact part number and provide a quote.
- Are NTN UCFL housings compatible with other brands?
- Yes, the main flange dimensions and shaft diameter follow international standards, so they are usually interchangeable between brands. Still, verify the hole center distance and insert type. Send us the original part number and we will give you the equivalent.
