The EXF is a four-bolt flange bearing unit that combines a flange housing with an insert bearing, designed to support a shaft on a flat surface. Bolting through the flange lets you fasten the unit to sheet metal or angle iron, while the extended inner ring of the insert grips the shaft. It is a compact option that is simple to align, which is why it shows up so often in power transmission work on agricultural, transport and general industrial equipment.

The letters EXF point to the family of square or rectangular flange housings supplied with an insert bearing, and the digits that follow give the size. Take EXF204 and EXF204-12: both fit the same shaft diameter, but the hyphenated version marks the inch measurement, in this case 12/16". The pattern repeats with EXF205, EXF205-14, EXF205-15 and EXF205-16, where the plain number is the metric size and the suffix the inch equivalent. Reading the code this way makes it straightforward to match the exact variant to the shaft in front of you.

Typical installations include conveyor belts, bucket elevators, grain elevators, agricultural machinery, bottling lines and ventilation systems, as well as food processing plants where flange mounting simplifies cleaning and teardown. Because these are self-aligning units, they absorb small misalignments and allow the bearing to be replaced without reworking the structure. MR Industrial Accessories LLC supplies this line for both replacement jobs and new projects.

Selection comes down to shaft diameter, the nature of the load (radial, axial or a combination) and the environment the unit works in. The insert seal may be a simple type or include an additional lip seal for dusty or damp conditions. Factory lubrication usually covers normal service, though demanding applications benefit from a relubrication schedule. During mounting, make sure the flange seats flat and tighten the bolts evenly so the insert is not distorted, and keep the housings aligned with each other to avoid added stress.

Flange units with inserts share their main dimensions across brands, but the way the insert locks onto the shaft can differ: set screws, eccentric collar or taper. When replacing an existing unit, check the shaft diameter, the hole spacing and the securing method. If you need a cross-reference from another brand, send the original part number and we will identify the compatible alternative.
