REXNORD ZN5000 series spherical roller bearings are double-row roller units with a spherical raceway, designed to withstand high radial loads and also moderate axial loads in both directions. Their design allows the shaft to operate with a certain misalignment relative to the housing without losing load capacity, which is key in equipment with long shaft spans, flexible frames or drives subject to vibration. MR Accesorios Industriales supplies them in Buenos Aires, Argentina, with more than 80 years of experience in the field.

The ZN5000 series designation is read in blocks: the letters ZN identify the spherical roller family, the following digits summarize the size and the two final letters MM indicate the product execution. In the examples ZN65050MM, ZN75055MM, ZN85060MM and ZN95075MM you can see how the numeric block changes according to size; therefore, to order the replacement it is best to provide the complete part number, exactly as it appears on the nameplate or on the equipment drawing.

In Argentine industry these bearings appear in belt conveyors, bucket elevators, mills, mixers, large centrifugal pumps, fans and crushing equipment. They are also found in road machinery, cranes and transmission systems where the shaft flexes or the housing is not perfectly aligned. It is a frequent solution in food, cement, mining and aggregate processing plants, where dust and continuous load demand a robust bearing with predictable maintenance.

To select the replacement, take into account the sealing type, internal clearance and the equipment's lubrication system. In applications with dust or moisture, effective protection against contaminants is advisable; in assemblies with misalignment, the spherical design absorbs angular error, but you must verify that the housing and shaft are in good condition. Lubrication must be the one specified by the equipment manufacturer and renewed according to service hours. Careful alignment and correct adjustment of the housing extend the service life of the assembly.

When looking for cross-brand equivalents, always compare by main dimensions, load type and execution, not only by part number. Different manufacturers use their own nomenclatures for spherical roller bearings, and the same size may have variants in cage, sealing or clearance. If the original part number is not available, the safest approach is to measure the seat and shaft and consult a specialist. MR Accesorios Industriales will indicate the compatible alternative for your application.
