The EXF housing is a 4-bolt flange mounted bearing unit with an integrated insert bearing. It is used to support shafts on flat structures, with front mounting via four bolts. The flange allows it to be fastened to sheet metal or angle iron, and the insert has an extended inner ring to fit the shaft. It is a compact, easy-to-align solution for power transmission in agricultural machinery, transport and industrial equipment.

The EXF designation identifies the series of square or rectangular flange housings with insert bearing. The numbers that follow indicate the size: for example, EXF204 and EXF204-12 correspond to the same shaft diameter, but the hyphenated suffix specifies the inch measurement (12/16"). The same applies to EXF205, EXF205-14, EXF205-15 and EXF205-16: the base number defines the metric diameter and the suffix the inch equivalent. This nomenclature lets you choose the exact variant for the shaft you have.

In Argentine industry, these housings appear in conveyor belts, bucket elevators, grain elevators, agricultural machinery, bottling equipment and ventilation systems. They are also found in the food industry, where flange mounting makes cleaning and disassembly easier. As self-aligning units, they tolerate small misalignments and simplify bearing replacement without modifying the structure. MR Accesorios Industriales sells this line for replacement and new projects.

To select the housing, take into account the shaft diameter, the type of load (radial, axial or combined) and the environmental conditions. The insert seal can be simple or with an additional lip seal for dusty or humid environments. Factory lubrication is usually sufficient, but in demanding applications it is advisable to schedule relubrication. When mounting, check that the flange sits well and that the bolts are tightened evenly so as not to deform the insert. Alignment between housings is key to avoiding stress.

Flange units with insert are interchangeable between brands as far as main dimensions are concerned, but the system for securing the insert to the shaft (set screws, eccentric or taper) may vary. If you are replacing an existing unit, compare the shaft diameter, the distance between holes and the type of securing. For cross-references with other brands, send us the part number of the original part and we will tell you the compatible alternative. At MR Accesorios Industriales we advise you so that the replacement is direct.
