Rexnord 4-bolt flange housings are mounted units that combine an insert bearing with a flange housing, designed to secure drive shafts to a flat surface. They are used in equipment where the shaft must sit perpendicular to the mounting surface and a firm hold with good load capacity is required. MR Accesorios Industriales sells this line for plants and workshops across Argentina.

The designation of these housings starts with the letters ZBR followed by four digits that identify size and configuration. For example, ZBR2308, ZBR2311 and ZBR2315 belong to the 2000 series, while ZBR3107, ZBR3111 and ZBR3115 fall under ZBR3000. Codes such as ZBR2400 and ZBR3203 complete the family. Each number refers to a shaft size and a housing type, so the code is the exact reference for ordering the replacement.

These housings appear in belt conveyors, bucket elevators, mixers, mills and process equipment. In Argentina they are found in food, cement and mining plants and in the field, where dust and weather demand a robust mounting. The four-bolt flange allows them to be fastened to frames, hoppers or sheet metal structures, and their design makes replacement easy without dismantling the whole assembly.

To choose well, take into account the shaft diameter, the type of load and the environmental conditions. If there is dust or water, a unit with reinforced sealing is advisable; if the shaft turns fast, check the lubrication and internal clearance. During mounting, rest the flange on a clean, flat surface, tighten the four bolts in a cross pattern and align the shaft before start-up. Poor alignment shortens bearing life.

Rexnord flange housings are interchangeable with other brands that use the same series nomenclature and dimensions. It can be replaced by an equivalent unit from another manufacturer as long as the shaft diameter, bolt hole spacing and sealing type match. MR Accesorios Industriales will point you to the compatible alternative so the equipment keeps running.
