The Rexnord ZA MMF housing is a 4-bolt flange mounted bearing unit, designed to secure rotating shafts to flat structures with simple, firm alignment. It is used in equipment where the bearing is flanged to a plate or housing, and the flange distributes the load across four points. MR Accesorios Industriales sells this line and will quote the part number you need via WhatsApp.

The ZA MMF designation reads in blocks: the letters ZA identify the flanged housing family, the number that follows defines the size and series variant, and the MMF suffix indicates the sealing and locking configuration specific to this line. In examples such as ZA2050MMF, ZA2055MMF or ZA2060MMF, the numeric portion changes with shaft diameter and load capacity, while MMF remains constant. The ZA6000 series, along with the 5000, 2000 and ZA9000 series, groups different combinations of size and mounting.

These housings appear in belt conveyors, bucket elevators, mixers, screens and continuous process lines. In food, cement, paper and aggregate processing plants they are chosen for the ease of mounting on sheet metal frames and for the ability to replace the bearing without fully disassembling the shaft. They are also found in pumping and ventilation equipment where the flanged housing simplifies fastening.

To select correctly, take into account the shaft diameter, the type of load and the direction of the forces. The 4-bolt flange requires a flat, rigid surface; parallelism should be checked and the appropriate bolts used. MMF sealing protects against dust and moisture, but in environments with pressurized water or fine particles additional protection may be needed. Lubrication must be the one specified for the inner bearing and renewed according to the duty cycle.

As for interchangeability, flanged housings from different brands often share mounting dimensions within the same series, but seals, clearances and tolerances do not always match. Before replacing a Rexnord with another brand, compare the shaft diameter, the hole spacing and the center height. MR Accesorios Industriales can indicate the compatible alternative or, if none exists, we quote it to measure.
