Rexnord ZB series housings are 4-bolt flange mounted bearing units, designed to secure rotating shafts to flat structures with simple, firm alignment. They are used in equipment where the bearing must be flanged to a plate or housing, transmitting radial loads and some axial thrust. MR Accesorios Industriales supplies this line as an official brand, with options for different shaft sizes and mounting configurations.

The ZB designation reads as a four-digit code: the first two digits indicate the housing type and the last two, the shaft size. For example, ZB2303, ZB2307 and ZB2308 share the 2000 series and vary in housing diameter; ZB3111 and ZB3115 correspond to the 3000 series, with higher capacity. The numeric suffix does not directly indicate the diameter in millimeters, so it is best to request a quote with the full part number and the required shaft size.

These housings are used in belt conveyors, bucket elevators, mixers, mills and process equipment in food, chemical and aggregate plants. In Argentina they are common in the oilseed, meatpacking and cement industries, where a robust, easy-to-maintain mounting is required. The 4-bolt flange allows them to be fastened to folded sheet metal or cast frames, with the possibility of rotating the housing to orient the load.

To select the housing, check the shaft size, the mounting type and the environmental conditions. If there is dust, water or frequent washdowns, choose versions with reinforced sealing; in clean environments, standard sealing is sufficient. During mounting, make sure the flange sits flat and tighten the bolts in a cross pattern to avoid deforming the housing. Lubrication must be as specified by the manufacturer and the internal clearance is not adjusted in this type of unit.

Equivalences between mounted housing brands are established by shaft size, flange type and load capacity, not by the part number. A Rexnord ZB can be replaced by units from other brands with the same configuration, but mounting and sealing dimensions must always be compared. MR Accesorios Industriales will indicate the compatible alternative if you cannot find the exact part number.

If you need a Rexnord ZB housing, send the full part number by WhatsApp to MR Accesorios Industriales. We will quote you shortly and, if you are looking for a variant that is not listed, write to us with the model or shaft size and we will indicate the corresponding option.

Frequently Asked Questions

What does the ZB code mean in Rexnord housings?
ZB identifies the family of 4-bolt flange mounted bearing units. The following digits indicate the series and shaft size. To request a quote, send us the full part number, for example ZB2307, and the quantity you need.
How do I choose between a 2000 series housing and a 3000 series housing?
The 3000 series has higher load capacity and is used on larger shafts or more demanding applications. The 2000 series is suitable for moderate loads. Compare the shaft size and working conditions; we can advise you on WhatsApp.
What should I consider when mounting a ZB housing?
Check that the mounting surface is flat and clean, tighten the bolts in a cross pattern and follow the specified lubrication. If the environment has dust or water, choose reinforced sealing. Shaft alignment is key to avoiding parasitic loads.
