The Rexnord ZEF housing is a 4-bolt flange mounted bearing unit, designed to secure rotating shafts to a flat surface and support moderate radial and axial loads. It is used in equipment where the bearing is bolted to a plate or structure, with the shaft passing through and the flange as the only anchoring point. MR Accesorios Industriales sells this Rexnord line and helps you identify the exact code your equipment needs.

The ZEF designation reads in blocks: the letters identify the family of flange units type E, and the numbers that follow order size and variant within the series. That is why ZEF codes share a format but change in size, and correspond to different scales within the same line. The ZEF series group different capacities and flange configurations.

These housings appear in belt and screw conveyors, bucket elevators, mixers, blowers, centrifugal pumps and packaging lines. In food, chemical, grain and aggregate processing plants they are chosen for the ease of mounting on metal structures and for the possibility of replacing the bearing without disassembling the whole assembly. They are also used in refrigeration equipment, industrial washdown areas and continuous process machines.

To select correctly, first look at the shaft diameter and the flange hole: the ZEF code must match both. Then define the sealing according to the environment: dust, water or frequent washdown require higher-protection seals. Correct lubrication and careful alignment when bolting the flange prevent parasitic loads and extend bearing life. If the equipment runs with vibration, check the tightness of the four bolts and the permissible axial clearance.

Flange housings from different brands with similar standardized dimensions coexist on the market, but interchangeability is not automatic: sealing, housing tolerance and fastening type change. Before replacing a ZEF with another brand, compare the shaft diameter, the hole spacing and the flange thickness. If you need a compatible alternative, at MR Accesorios Industriales we tell you which one fits your mounting.

To request a quote, send us on WhatsApp the complete code shown on the housing or in the equipment manual, for example ZEF2107 or ZEF2203. With that data we identify the variant and send you the quote shortly. If the code is erased or the housing is no longer legible, tell us the shaft diameter and the flange hole spacing, and we will help you find the replacement.
