Rexnord 9000 series 4-bolt flange bearing housings are mounted units that combine an insert bearing with a flange housing, ready to be fixed to a vertical or horizontal surface. They are used to guide shafts in equipment where firm, compact support is needed, such as conveyor belts, mixers or pumps. MR Accesorios Industriales sells this line and advises you on choosing the correct configuration for your application.

The designation of these housings starts with the letters ZAS, which identify the 4-bolt flange family. The digits that follow indicate the size and type of housing: for example, ZAS9115F72 and ZAS9200F72 share the 9000 series but vary in dimensions and in the shaft diameter they accept. The F72 suffix appears in the examples and distinguishes a specific construction variant within the series. To select the correct part number, have the shaft diameter and the mounting dimensions of your equipment at hand.

These housings are used in a wide variety of industries in Argentina: food plants, material handling, water treatment, mining and general manufacturing. They are common in equipment such as bucket elevators, blowers, agitators and belt conveyors, where the flange allows rigid fastening on metal structures or masonry. Their 4-bolt design facilitates alignment and distributes loads better than a 2-bolt flange housing.

When choosing a flange housing, verify that the shaft diameter matches that of the insert bearing and that the distance between flange holes is compatible with your mounting surface. Also check the sealing type: for dusty or humid environments, additional protection is advisable. Mounting must be done on a flat, clean surface, tightening the bolts in a cross pattern to prevent deformation. Proper lubrication and careful alignment extend the service life of the assembly.

Rexnord 9000 series housings can be interchanged with units from other brands that follow the same flange standard and shaft diameter. In general, interchangeability depends on the flange dimensions, the center height and the locking type of the insert bearing. If you need to replace an existing housing, the most practical approach is to compare the housing and shaft dimensions. MR Accesorios Industriales will indicate the compatible alternative within its housing line.
