Description
REXNORD ZB5107 belongs to flange bearing 3 holes, part of our Bearing housings range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for ZB5107 and any equivalents.
The ZB family from Rexnord covers three-bolt flange housings: bearing units that hold a rotating shaft against a metal or concrete frame. They suit installations where the shaft needs firm, centered support and where the assembly can only be fastened from one side. MR Industrial Accessories LLC supplies this line and helps buyers match a housing to shaft size and load conditions.
Reading the code is the fastest way to narrow down a ZB housing. Letters and digits together describe both the housing style and the shaft it accepts. Take ZB3107, ZB5107 and ZB6107: the leading digit changes with the series of bearing that fits inside, while the final pair of digits points to the shaft diameter, given in inches or its metric equivalent. Suffixes, when present, flag sealing or fastening variations. Because of this, the safest route is to send us the complete model before ordering.
Typical duty for these units includes conveying, lifting and process equipment, wherever a shaft has to stay supported and aligned. You will see them on conveyor belts, bucket elevators, mixers, pumps, fans and beverage or food machinery, and also in water treatment plants, sugar mills and mining operations. The three-bolt flange pattern mounts onto folded sheet metal or structural profiles, and its layout allows radial adjustment while keeping the housing from turning.
Choosing a housing comes down to three inputs: shaft diameter, the nature of the load (radial, axial or a combination) and the surrounding environment. Sealing deserves particular attention, since dusty, wet or frequently washed areas call for reinforced protection. Use the lubricant specified for the mounted bearing and renew it according to the duty cycle. At installation, make sure the flange sits flat and tighten the bolts evenly so the housing is not distorted; proper alignment pays off in service life.
Rexnord housings can be swapped with other brands of flange mounted bearings when shaft diameter, hole spacing and center height all line up. A similar part number is not enough on its own; compare the critical dimensions and how the bearing is secured. For a replacement job, send a photo or the original housing number and we will identify a compatible option from our catalog.

Frequently asked questions
- What does ZB mean in a Rexnord housing?
- ZB identifies Rexnord's flange unit family, and the model determines how many flange holes it has. The digits that follow cover the mounted bearing series and the shaft diameter; ZB3107, for instance, pairs the 3000 series with a 1 7/16 inch shaft. Send us the full part number and we will confirm the exact variant.
- How do I pick the right housing for my application?
- Start with the shaft diameter, the load type and the working conditions, then factor in sealing if dust or moisture is present. With those details we can point you to the ZB model that fits. If you already have the original housing number, share it and we will look for the equivalent.
- Do Rexnord housings fit other brands?
- They interchange with other flange mounted bearing brands provided the critical dimensions agree: shaft diameter, distance between holes and center height. The part number alone will not confirm it. Send the dimensions or a photo and we will verify the compatible alternative.
