Rexnord 4-bolt flange bearings are mounted units that combine an insert bearing with a square or round flange housing, designed to fix shafts to walls, sheet metal or structures. They are used when the shaft must be perpendicular to the mounting plane and the load combines radial with moderate axial thrust. MR Accesorios Industriales sells this line and advises you on choosing the correct variant according to the shaft diameter and the type of mounting.

The designation of these bearings is read in blocks: the prefix ZBS identifies the flange housing family, the four digits that follow combine the shaft size and the insert type, and the suffix MM indicates the sealing variant and configuration of the unit. In the examples of the 2000 series, such as ZBS2080MM or ZBS2085MM, the central digits refer to the nominal shaft diameter and the insert bearing series; those of the 5000 series, such as ZBS5040MM or ZBS5055MM, follow the same logic with another dimensional base. To interpret each part number, consult the manufacturer's equivalence table.

These pillow blocks appear in belt and roller conveyors, bucket elevators, mixers, blowers, centrifugal pumps and process equipment in food, chemical and aggregate processing plants. In Argentina they are found in packaging lines, grain conveyor belts, mills and animal feed plants. The 4-bolt flange allows mounting on folded sheet metal or profile structures, with the shaft coming out perpendicular to the mounting surface, which simplifies alignment in equipment where the housing is bolted to a frame.

To select the housing, start from the shaft diameter and the type of load: if radial predominates, a standard unit is enough; if there is axial thrust, it is advisable to verify the capacity of the insert. Sealing is key in environments with dust, water or washing: variants with contact seal and additional lip protect the lubricant better. During mounting, tighten the four bolts in a cross pattern and with a torque wrench to avoid deforming the flange, verify that the shaft turns freely and grease the insert according to the duty cycle. A slight angular misalignment is absorbed by the internal clearance of the bearing, but it is advisable to correct it before start-up.

Rexnord and Link-Belt share nomenclature in many of their mounted bearing lines, and several manufacturers offer equivalent units with their own part numbers. Interchangeability depends on the shaft diameter, the insert type, the distance between flange holes and the sealing. When requesting an alternative, send the complete part number and the working conditions: this way the load capacity and the mounting type can be compared without the risk of mounting a unit that does not correspond.
