The NSK AELFB series Y-bearing housing unit is a 4-bolt flange mounted bearing unit, designed to secure rotating shafts to flat structures. It is used in equipment that requires firm support and simple alignment, such as conveyor belts, fans or agricultural machinery. MR Accesorios Industriales sells this series in Buenos Aires, Argentina, and advises you on choosing the correct size for your application.
The AELFB series designation is read in parts: the letters AELFB identify the type of housing with a 4-bolt square flange insert bearing. The numbers that follow indicate the shaft diameter and the housing size; for example, AELFB201-008W3 corresponds to an 8 mm shaft, while AELFB201W3 is for a 12 mm shaft. The W3 suffix indicates the presence of a triple lip seal, which improves protection against dust and moisture. Send us the complete code so we can quote the exact reference.
These housings are used in a wide variety of industries in Argentina. You will find them in belt conveyors, food industry machines, packaging equipment, ventilation systems and agricultural machinery. Their 4-bolt flange allows quick mounting on flat surfaces, with the possibility of aligning the shaft at the time of installation. They are a practical solution for shafts that rotate at moderate speeds and require robust, easy-to-maintain support.
To select the right housing, take into account the shaft diameter, the type of load (radial, axial or combined) and the environmental conditions. The W3 seal offers greater resistance to contamination, ideal for environments with dust or moisture. During mounting, make sure the support surface is clean and flat, and that the fastening bolts are tightened evenly to avoid deformation. The lifetime lubrication of the insert bearing simplifies maintenance, although in severe applications periodic relubrication may be necessary.
As for equivalents, NSK AELFB series housings can be interchanged with products from other brands that follow the same 4-bolt flange standard and standardized shaft diameters. If you have the code from another brand, we can tell you the equivalent NSK reference. Remember that interchangeability depends on the exact dimensions and the type of seal. To ensure compatibility, it is always advisable to verify the critical dimensions before replacing a housing.
