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

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

These units appear in belt conveyors, bucket elevators, mixers, mills and process equipment. In Argentina they are seen in food, cement and mining plants and in the field, where dust and weather demand robust mounting. The four-bolt flange allows them to be fastened to chassis, hoppers or sheet metal frames, and their design facilitates replacement without disassembling the entire assembly.

To choose correctly, take into account the shaft diameter, load type and environmental conditions. If there is dust or water, a unit with reinforced sealing is advisable; if the shaft rotates fast, check 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 starting up. Poor alignment shortens bearing life.

Rexnord flange bearing units are interchangeable with other brands that use the same series nomenclature and dimensions. If the original code is not available, it can be replaced by an equivalent unit from another manufacturer, respecting shaft diameter, bolt hole spacing and sealing type. MR Accesorios Industriales will indicate the compatible alternative so your equipment keeps running.
