The Rexnord ZEF is a four-bolt flange housing that mounts a bearing to a flat surface, holding rotating shafts and handling moderate radial and axial loads. The flange is the sole anchor point, with the shaft passing through. MR Industrial Accessories supplies this Rexnord line and helps you pinpoint the exact code your equipment requires.
A ZEF code breaks down into parts: the letters denote the flange unit family type E, while the following digits indicate size and variant within the series. Consequently, ZEF codes follow a common pattern but differ in size, covering various scales in the same line. The series spans multiple capacities and flange arrangements.
Typical installations include belt and screw conveyors, bucket elevators, mixers, blowers, centrifugal pumps, and packaging lines. Food, chemical, grain, and aggregate plants favor them for straightforward mounting on metal structures and the ability to swap the bearing without dismantling the entire assembly. They also appear in refrigeration equipment, washdown zones, and continuous process machinery.
Selection starts with the shaft diameter and flange hole pattern; the ZEF code must align with both. Next, choose the seal based on the environment: dust, water, or frequent washdown calls for higher-protection seals. Proper lubrication and careful alignment during flange bolting avoid parasitic loads and prolong bearing life. In vibrating equipment, verify the four bolts stay tight and check permissible axial clearance.
Flange housings from various brands with similar standardized dimensions are available, but they are not automatically interchangeable: sealing, housing tolerance, and fastening method vary. Before substituting a ZEF with another brand, compare shaft diameter, hole spacing, and flange thickness. If you need a compatible option, MR Industrial Accessories can identify which one suits your mounting.
To get a quote, send the complete code from the housing or equipment manual via WhatsApp, for example ZEF2107 or ZEF2203. With that information, we identify the variant and provide a quote promptly. If the code is illegible or missing, provide the shaft diameter and flange hole spacing, and we will help you find the replacement.

Frequently asked questions
- How do I identify the ZEF code of my housing?
- Check for the code stamped on the flange or bearing. If it is not readable, measure the shaft diameter and the distance between the four holes. With that data, we can tell you which ZEF matches your equipment.
- Can a ZEF be replaced by another brand?
- Sometimes, but matching shaft diameter alone is not enough. You must also compare hole spacing, flange thickness, and seal type. Send us those measurements and we will advise which compatible alternative fits.
- What lubrication does a ZEF flange housing use?
- It depends on the duty cycle and environment. Generally, industrial-grade grease is used, and the seal condition is checked. If the equipment sees washdowns or heavy dust, lubrication should be inspected more often.
