The NSK UELFU is a four-bolt flange mounted unit that combines an insert bearing with a cast iron housing. It bolts to a flat surface and accepts a shaft, so it suits equipment that needs rigid support with straightforward alignment, including conveyors, fans, mixers and agricultural machinery. The insert can be mounted or removed without pulling the shaft apart. MR Industrial Accessories LLC supplies this line to plants and workshops across the United States and in several Latin American countries.

The UELFU code identifies a four-bolt flange unit with insert bearing. The digits that follow give the nominal shaft size. In codes with a hyphen, the number after it states the measurement in inches: UELFU204-012D1W3 fits a 3/4 inch shaft, and UELFU205-100D1W3 fits a 1 inch shaft. Without a hyphen, the measurement is metric. Where a hyphen appears, the number after it clarifies the inch measurement, so UELFU206-101D1W3 is for a 1 inch and 1/16 shaft. The D1 and W3 suffixes denote sealing variants and tolerances within the series.

Typical installations include belt conveyors, bucket elevators, mills, mixers, blowers and process equipment in food, chemical, cement and agricultural operations. The four-bolt flange simplifies mounting onto sheet metal or profile structures. The design accommodates slight misalignment and combined radial and axial loads, and maintenance is straightforward.

When selecting a unit, confirm the shaft diameter and the fixing method: the UELFU flange is bolted with four bolts. Match the sealing to the environment, since the D1 and W3 suffixes indicate additional protection against dust and moisture. The insert bearing normally arrives pre-lubricated; in demanding applications, check lubrication and axial clearance. During mounting, align the flange with the shaft and tighten the insert set screws evenly to avoid stress.

NSK UELFU units interchange with other brands that follow the same dimensional nomenclature, such as SKF, FAG, NTN or Timken, provided the shaft diameter and flange dimensions match. If you have a competitor's code, we can identify the equivalent. We can also quote the exact size you need.
