Rexnord 4-bolt flange bearing units are mounted units that combine an insert bearing with a square or round flange housing, depending on the series. They are fastened with four bolts to the structure and support rotating shafts in equipment where flange mounting simplifies alignment and replacement. In Argentine industry they are used in conveyors, agitators, pumps, fans and process lines where firm fastening and a bearing protected against dust and moisture are required.

The designation of these units is read in blocks. The letters ZA identify the 4-bolt flange family; the numbers that follow indicate the size and the housing series, and the final letter F indicates the type of fastening or the flange material. For example, ZA2115F and ZA2200F correspond to the 2000 series, while ZA2203F, ZA2204F and ZA2208F cover increasing shaft diameters within that same line. The ZA6000, 5000, 2000 and ZA9000 series group different capacities and flange configurations.

In Argentine plants, these units appear in belt and chain conveyors, mixers, dryers, bucket elevators and water treatment equipment. They are also found in the food, chemical and cement industries, where flange mounting allows horizontal or vertical shafts to be supported in tight spaces. Being mounted units, they simplify assembly and maintenance: the complete unit is replaced without disassembling the shaft or the structure.

To select the correct unit, take into account the shaft diameter, the type of load (radial, axial or combined), the rotation speed and the environmental conditions. Check the sealing: units with single or double lip seals provide better protection against dust and water. Factory lubrication can be supplemented with periodic greasing according to the duty cycle. During mounting, make sure the flange sits flat on the surface and that the four bolts are properly tightened to avoid deformation and misalignment.

Rexnord units are interchangeable with units from other brands that follow the same dimensional and mounting standards. When requesting a quote, it is advisable to compare the shaft diameter, the distance between flange holes, the housing outside diameter and the type of insert bearing. MR Accesorios Industriales sells Rexnord as an official brand and can indicate the compatible alternative if you need to replace an existing unit.
