The NSK AELFB series Y-bearing housing unit is a flange-mounted assembly that supports rotating shafts on flat surfaces. It uses a 4-bolt square flange, making it suitable for conveyors, fans, and agricultural equipment. MR Industrial Accessories supplies this series and can help you select the right size for your application.
The AELFB code breaks down into two parts: AELFB indicates a 4-bolt square flange housing with an insert bearing. The following numbers specify shaft diameter and housing size. For instance, AELFB201-008W3 fits an 8 mm shaft, while AELFB201W3 fits a 12 mm shaft. The W3 suffix means the bearing has a triple lip seal for better protection against dust and moisture. Provide the full code when requesting a quote.
These units are common in belt conveyors, food processing machines, packaging equipment, ventilation systems, and agricultural machinery. The 4-bolt flange allows quick mounting on flat surfaces and shaft alignment during installation. They are a practical choice for moderate-speed shafts that need sturdy, easy-to-maintain support.
When selecting a housing, consider shaft diameter, load type (radial, axial, or combined), and environmental conditions. The W3 seal offers greater resistance to contamination, making it suitable for dusty or wet environments. During mounting, ensure the support surface is clean and flat, and tighten the bolts evenly to prevent deformation. The insert bearing is lubricated for life, which simplifies maintenance, but relubrication may be needed in severe applications.
NSK AELFB housings can be interchanged with other brands that follow the same 4-bolt flange standard and shaft diameters. If you have a code from another manufacturer, we can identify the equivalent NSK reference. However, interchangeability depends on exact dimensions and seal type, so always verify critical dimensions before replacing a housing.
