Rexnord ZEF2000 series housings are 4-bolt flange mounted bearings, designed to secure transmission shafts directly onto a flat machine or structure face. They are used when a rigid, centered, front-mount support is needed, with the shaft passing through and the housing bolted from the front. MR Accesorios Industriales sells this line and advises you on choosing the right variant for your application.
The designation of these housings is read in blocks. The letters ZEF identify the family of E-type flange units; the number that follows, as in ZEF2035MM or ZEF2040MM, orders the size within the series. The MM suffix closes the reference and indicates the sealing and mounting configuration with which each size is assembled. That is why, when requesting a replacement, it is best to provide the complete part number: the different part numbers in the series are not interchangeable with each other even though they share the family.
These housings appear in conveyor lines, elevators, mixers, pumps, fans and process equipment. In food, chemical, cement and aggregate processing plants they are chosen for the ease of front mounting and the rigidity provided by the 4-bolt flange. They are also found in agricultural machinery and material handling equipment, where the support must be well centered and withstand forces in several directions without shifting.
To select correctly, first look at the shaft diameter and the load the support will bear. Then check the sealing: in environments with dust, water or frequent washdown, a more closed protection is advisable. Mounting requires a flat, clean surface, with the four bolts tightened in a cross pattern and without forcing alignment. Correct lubrication and a start-up free of impacts extend the life of the mounted bearing. If the shaft is not aligned, the housing works crooked and fails earlier.
Rexnord is a recognized brand in mounted bearings and housings, and its series often have equivalents in other lines on the market. Interchangeability is not defined by shaft diameter alone: the distance between holes, the type of sealing and the housing height change. That is why, when looking for a replacement, compare the complete designation and the mounting dimensions. If you cannot find the exact reference, at MR we point you to the compatible alternative for your equipment.
If you need a flange housing for your machine, send us the part number by WhatsApp. At MR Accesorios Industriales we quote it shortly and help you define the variant that best suits your shaft and working conditions. We know the industrial applications of Buenos Aires, Argentina, and we support you in the selection.

Frequently Asked Questions
- How do I request a quote for a ZEF2000 housing?
- Write to us on WhatsApp with the complete part number, for example ZEF2045MM, and the quantity you need. With that we quote it shortly and confirm the variant available for your application.
- What does the MM suffix in the reference mean?
- The MM suffix is part of the factory designation and identifies the sealing and mounting configuration of each size. That is why you should not replace a ZEF2035MM with another part number just because they share the ZEF2000 series.
- Is it suitable for dusty or humid environments?
- Yes, as long as you choose the right sealing for those conditions. In applications with dust, water or frequent washdowns, a more closed protection is advisable. Tell us how your equipment works and we will guide you in the selection.
