The NTN UELFU series is a four-bolt flange mounted bearing unit that supports rotating shafts on flat surfaces. The insert bearing arrives already fitted and aligned inside the housing, which simplifies installation and keeps the assembly compact for power transmission applications that need firm fastening.
Reading the code helps you order the right unit. The first letter stands for an insert bearing unit, the ELF block identifies the four-bolt flange, and the closing letter indicates how the insert locks to the shaft. The digits that follow give the shaft diameter: UELFU204 fits a 20 mm shaft, UELFU205 a 25 mm shaft, UELFU206 a 30 mm shaft. Suffixes D1 and W3 mark sealing and configuration variants, and a hyphenated reference such as UELFU204-012 uses the numeric suffix for an inch measurement.
These units appear across food processing, material handling, agricultural equipment, packaging lines, ventilation systems and chemical operations. The four-bolt flange mounts on flat surfaces such as sheet metal walls or profile structures, holding shafts that turn at moderate speeds.
When selecting a unit, check the shaft diameter, whether the load is radial, axial or combined, and the working environment. The D1 seal guards against dust and moisture, while the W3 variant may add sealing features. At mounting, verify alignment and lubrication: the insert normally ships pre-lubricated, but its condition should be checked and grease reapplied according to the operating regime.
NTN UELFU units interchange with other brands built to the same four-bolt flange standard and shaft diameters. Send the part number from another brand and we will identify the equivalent NTN reference. MR Industrial Accessories LLC supplies NTN mounted bearings.
