Rexnord ZA series housings are pillow block units that house mounted bearings and are used to support rotating shafts in transmission equipment. They are used in conveyors, mixers, pumps and machinery in general, where a robust support and stable alignment are needed. MR Accesorios Industriales sells this line in Buenos Aires, Argentina, and advises you on choosing the right housing for your shaft and load.

The designation of these housings combines letters and numbers that identify the unit type and its size. In the ZA series, the examples ZA2080MM, ZA2085MM and ZA2090MM correspond to pillow block housings with mounted bearings; the ZA6035MM, ZA6040MM and ZA6045MM belong to the ZA6000 variant, and the ZA9000 complete the family. The MM suffix indicates the seal type or unit configuration. To interpret each code, it's best to consult the manufacturer's catalogue or write to us with the full part number.

In Argentine industry, these housings are seen in belt conveyors, bucket elevators, mixers, mills, centrifugal pumps and process equipment. They also appear in food, cement, mining and aggregate processing plants, where the environment is demanding and a support that withstands dust and moisture is required. Being mounted units, they simplify assembly and maintenance because the bearing and housing form a ready-to-install assembly.

To select the right housing, take into account the shaft diameter, the load type, the rotation speed and the environmental conditions. Sealing is key: in environments with dust or water, additional protection is advisable. Lubrication must be the one specified by the manufacturer and the internal clearance and alignment must be checked during assembly to avoid stress. If the housing runs misaligned, bearing life is reduced. MR Accesorios Industriales can guide you on these criteria.

Rexnord housings can be interchanged with those of other brands that follow the same standardized dimensions, but the exact equivalence depends on the series and the mounting type. It's not enough for the shaft diameter to match: you must verify the center height, the hole spacing and the sealing system. If you need to replace an existing housing, send us the original part number or the main dimensions and we'll tell you the compatible alternative.
