The NTN JELFU series is a Y-bearing unit built around a 4-bolt flange housing. It fastens a rotating shaft to a flat surface and suits equipment that needs a stable mount and straightforward alignment, including conveyors, fans and agricultural machines. Bearing and housing come as one assembly, so installation is simpler and upkeep is easier. MR Industrial Accessories supplies this series.
Reading the code helps you pick the right unit. The J at the start denotes the housing family; ELFU points to the 4-bolt flange version with a set screw insert. The trailing number, as in JELFU-1 or JELFU-2, sets the bearing and housing size. That structure lets a maintenance tech match a unit to a shaft diameter quickly.
Typical duty includes belt conveyors, mixers, screens, mills and process lines, plus food, chemical and aggregate operations. The four-bolt flange bolts to sheet metal or profile structures, while the insert bearing absorbs small misalignments, which helps in areas with vibration or moderate loads.
Selection starts with shaft diameter, then radial and axial loads, then the environment. The insert seal keeps out dust and moisture; for washdown areas, confirm the seal style. Mount on a flat, clean surface and tighten the set screw with the correct wrench so the inner ring is not distorted. Regular greasing with a good grease keeps the unit running smoothly.
NTN JELFU units interchange with other brands that share the same 4-bolt flange pattern and equivalent shaft sizes. When swapping, check flange dimensions, hole spacing and shaft diameter. A part number or nameplate photo usually pins down the exact equivalent; our team can help confirm it.
