The ASFD housing is a 4-bolt flange mounted bearing unit: it combines an insert bearing with a cast iron housing that is fastened to the structure with four bolts. It is used to support rotating shafts in equipment where firm fastening and simple mounting are required, with the flange as the anchoring surface. MR Accesorios Industriales sells this NSK line in Buenos Aires, Argentina, and will quote the exact part number you need.

The ASFD designation is read as a four-bolt flange unit of the ASFD series. The numbers that follow identify the size, which corresponds to a metric shaft diameter. When a hyphenated suffix appears, the second part indicates an inch shaft dimension or a mounting variant. Send the full part number and we will quote the assembled unit.

These units are used in conveyors, belts, agitators, blowers, centrifugal pumps and process equipment. In Argentine plants they appear in packaging lines, mills, water treatment plants and ventilation systems. The four-bolt flange allows the unit to be fastened to a flat face and the shaft to be aligned easily, which is useful when the housing is mounted on folded sheet metal or profile structures.

To select correctly, check the shaft diameter and the mounting type. The insert bearing usually comes with set screws or with an eccentric collar; the seal can be single or double contact. During mounting, rest the flange on a clean, flat surface, tighten the four bolts in a cross pattern and check that the shaft turns without effort. Lubricate according to the duty cycle and check alignment to avoid side loads.

Four-bolt flange units are interchangeable between brands if the shaft diameter, the bolt circle diameter and the center distance match. An NSK ASFD part number can be replaced by equivalent units from other brands with the same configuration. If you bring the original part or another brand's part number, we will tell you the compatible alternative and quote it for you.
