The UELFLU series 4-bolt flange Y-bearing unit is an assembled unit that combines a cast iron housing with four mounting holes and an insert bearing with set screws. It is used to support rotating shafts on flat structures, where firm fixing and simple alignment are required. MR Accesorios Industriales sells this NSK line for industrial and agricultural applications.

The UELFLU designation is read in parts: UEL indicates the insert bearing with set screws and a wider inner width; FL corresponds to the 4-bolt flange; U indicates the mounting type. The numbers that follow identify the shaft diameter: for example, UELFLU204D1W3 and UELFLU204-012D1W3 share the base size, while UELFLU205-013D1W3 and UELFLU205-014D1W3 vary in bore tolerance. The suffix D1 refers to the polyamide cage and W3 to the set screw thread.

These units are found in belt conveyors, packaging lines, flour mills, feed plants and irrigation equipment. In Argentina they are common in the meatpacking industry, in maneuvering yards and in agricultural machinery, where mounting on sheet metal or structural profile requires a rigid flange and a bearing that tolerates slight misalignment. The UELFLU series covers shafts from 20 mm to 50 mm, with inch variants for direct replacement.

To choose correctly, take into account the shaft diameter, the type of load and the environmental conditions. The insert's sealing protects against dust and moisture; if there are frequent washdowns, it is advisable to verify the seal type. Internal clearance and lubrication are already defined at the factory, but mounting must ensure that the flange rests on a flat surface and that the four bolts are tightened evenly. The set screws are tightened onto the shaft with the appropriate wrench, without hammering.

Equivalences between brands are common: a 4-bolt flange unit with a UEL insert can be interchanged with references from other companies that follow the same dimensional standard. If the customer brings a part number from another brand, at MR we cross-reference it and quote the equivalent NSK option. Interchangeability depends on the shaft diameter, the distance between holes and the center height, data that should be confirmed before replacing.
