The Rexnord ZB series flange bearing housing is a four-bolt mounted bearing that fastens to a flat surface to support rotating shafts. It is used when the shaft runs parallel to the wall or structure and a rigid, centered support is required. MR Accesorios Industriales carries this line as an official brand, with alternatives for different shaft sizes and sealing configurations.
The ZB designation combines letters and numbers that identify the housing type and shaft diameter. In examples ZB2080MM, ZB2085MM and ZB2090MM, the numeric block indicates the shaft size and the MM suffix indicates the unit system. The 2000 series is the basis of this family, while the ZB5000 and ZB9000 variants cover other combinations of size and fastening. To choose, send us the complete part number shown on the nameplate or drawing.
These housings are found in belt conveyors, bucket elevators, mixers, mills and process equipment. In food, chemical and aggregate plants in Argentina, the four-bolt flange simplifies mounting on sheet metal frames or profile structures. They also appear in industrial fans and centrifugal pumps where a robust and easily aligned support is needed.
To select the housing, verify the shaft diameter, the distance between holes and the required load capacity. Sealing is key: in dusty or humid environments, additional protection is advisable. During installation, make sure the flange sits flat and the bolts are tightened evenly to avoid deformation. Lubrication must follow the manufacturer's instructions and be renewed according to the duty cycle.
Rexnord flange bearing housings are interchangeable with other brands that use the same mounting standard and shaft sizes. When requesting a quote, stating the complete part number and the original brand helps find the right equivalence. MR Accesorios Industriales can indicate the compatible alternative or, if needed, we manufacture it to measure. Send us the part number on WhatsApp and we will quote you promptly.

Frequently Asked Questions
- What does the MM suffix mean in ZB housings?
- The MM suffix indicates that the housing is dimensioned in the metric system. It is important to verify this data when replacing a mounted bearing, because the shaft diameter and the mounting holes must match the existing installation.
- How do I choose the right flange bearing housing for my application?
- You need the shaft diameter, the distance between hole centers and the type of load. The environment also matters: if there is dust, water or chemicals, reinforced sealing is advisable. With that data, we will indicate the Rexnord part number that best fits.
- Do Rexnord housings have equivalents from other brands?
- Yes, many flange bearing housings follow dimensional standards that allow interchange between manufacturers. To find the correct equivalence, send us the complete part number and the brand of the original equipment. That way we can give you the alternative that meets the same mounting dimensions.
