Rexnord ZB line housings are 3-bolt flange mounted bearing units, designed to secure rotating shafts to metal or concrete structures. They are used when firm, centered fastening is needed, with the option of mounting the assembly from one side only. MR Accesorios Industriales sells this brand and advises you on choosing the model according to shaft diameter and load type.
The designation of these housings combines letters and numbers that identify the housing type and the shaft diameter. In the ZB series, examples ZB3107, ZB5107 and ZB6107 show how the first digit varies according to the mounted bearing series. The last two digits usually indicate the shaft diameter in inches or its metric equivalent, and suffixes may appear that indicate sealing or fastening variants. To correctly interpret each part number, it is best to consult us with the exact model.
These housings are used in conveying, lifting and process equipment where the shaft must be supported and aligned. In Argentina we find them in conveyor belts, bucket elevators, mixers, pumps, fans and machinery for food and beverages. Also in water treatment plants, sugar mills and mining facilities. The 3-bolt flange allows them to be mounted on folded sheet metal or profile structures, with a layout that facilitates radial adjustment and prevents rotation of the housing.
To select the right housing, consider the shaft diameter, the load type (radial, axial or combined) and the environmental conditions. Sealing is key: in environments with dust, water or frequent washdowns, reinforced protection is advisable. Lubrication must be the one specified for the mounted bearing and renewed according to the duty cycle. During mounting, verify that the flange rests flat and that the bolts are tightened evenly so as not to deform the housing. Correct alignment extends the life of the assembly.
Rexnord housings are interchangeable with other brands of flange mounted bearings, as long as the shaft diameter, the distance between holes and the center height match. It is not enough for the part number to be similar: you must compare the critical dimensions and the bearing fastening type. If you need to replace existing equipment, send us a photo or the part number of the original housing and we will point you to the compatible alternative in our catalog.

Frequently Asked Questions
- What does the ZB designation mean in Rexnord housings?
- The ZB code identifies Rexnord's family of flange units; the number of flange holes depends on the model. The numbers that follow indicate the mounted bearing series and the shaft diameter. For example, ZB3107 corresponds to the 3000 series and a 1 7/16 inch shaft. Consult us with the complete part number to confirm the variant.
- How do I choose the right housing for my application?
- You need to know the shaft diameter, the load type and the working conditions. Sealing is also important if there is dust or moisture. With that data we will point you to the ZB model that best suits you. If you have the part number of the original housing, send it to us and we will look for the equivalent.
- Are Rexnord housings compatible with other brands?
- Yes, they are interchangeable with other brands of flange mounted bearings as long as the critical dimensions match: shaft diameter, distance between holes and center height. Do not rely on the part number alone. Send us the dimensions or a photo and we will confirm the compatible alternative.
