Rexnord in agriculture: components for combines, seeders, norias and storage plants

Rexnord spherical roller bearings are a common choice for shafts in combines, headers and trailed equipment that work with heavy loads and some misalignment. Their design with two rows of rollers and a spherical raceway in the outer ring allows them to absorb small shaft deviations without losing load capacity. In agriculture, this is noticeable on uneven terrain or when the equipment vibrates during harvest.

To identify them, the code is usually engraved on the side face of the outer ring, for example 2400U, 2311U or 5200U. It is also advisable to note the inner diameter, outer diameter and width measurements, because on equipment with many hours of use the engraving may be blurred. If the bearing is mounted, sometimes measuring the shaft and the housing is enough to deduce the series.

When ordering a spherical roller bearing for agriculture, it is useful to indicate the machine and model, in addition to the code. At MR we distribute the Rexnord line and quote you via WhatsApp or email with that data. A common mistake is replacing a spherical roller bearing with a rigid ball bearing: it does not compensate for misalignment and ends up failing prematurely.

Y-bearings, also called inserts, are bearing units with a spherical outer ring that are mounted inside a pillow block or flanged housing. In agriculture they appear in augers, chopper rotors, cleaning fans and other shafts that rotate at medium speeds with radial load. The advantage is that the housing-bearing assembly self-aligns during mounting.

Inserts can have different shaft locking systems, such as set screws, eccentric collar or adapter sleeve. Example codes are 3111U, 3115U and 3107U. Always verify the shaft diameter in millimeters or inches before ordering.

To quote a Y-bearing, send us the complete code and the shaft measurement. We distribute Rexnord and quote you with that data. A common mistake is confusing the insert with the housing: they are separate parts although they are often sold together.

Rexnord housings are the casings where bearings are seated, and in storage plants they are used in norias, belt conveyors and augers. They can be pillow blocks, flanged or take-up units, and are chosen according to shaft position and mounting method. A well-chosen housing simplifies maintenance because it allows adjusting belt or chain tension.

In the Rexnord catalog, housings have codes such as ZA9215, ZB9115 or ZB6307. You don't need to memorize the nomenclature: the code engraved on the casing is enough for us to quote the exact replacement.

When ordering a housing for agriculture, it is advisable to clarify whether it is mounted on a noria, a conveyor or an auger, because the dust and humidity environment influences the type of seal. At MR we distribute Rexnord housings and indicate the correct alternative for your equipment. Avoid reusing damaged housings: an ovalized seat causes the new bearing to fail prematurely.

The Y-housing with insert bearing is an assembly that combines a cast iron or sheet steel casing with a spherical outer ring insert. It comes factory-assembled and mounts directly onto the shaft, saving time during harvest-season repairs. In agriculture it is used on noria shafts, feed mixers, baggers and other equipment requiring a simple support point.

Example codes such as P2B-208-T, P2B-307-T or P4B-207-T are housing assemblies with insert bearing. If you have the old assembly, a photo of the engraving and the shaft measurement are enough to quote.

When ordering a Y-housing with insert, it is important to know whether the shaft is metric or inch, because the measurements of each system are not interchangeable. We distribute these assemblies and quote them via WhatsApp or email with the code or photo. A frequent mistake is ordering only the insert when the housing is also worn: it is advisable to check the seat before purchasing.

Rexnord friction bushings are cylindrical bushings that work with sliding motion, without rolling elements. In agricultural machinery they are used in arm joints, hopper pivot points, wheel shafts of trailed equipment and other places where motion is oscillating or slow. Their advantage is that they support high loads in confined spaces.

Example codes such as 701-66032-128, 701-60064-256 or 701-60048-192 correspond to friction bushings. If the code is not legible, measuring the inner diameter, outer diameter and width with a caliper is the safest way to identify it.

To quote a friction bushing, send us the code or the three measurements and the machine where it is mounted. At MR we distribute the Rexnord line and indicate the appropriate replacement. A common mistake is replacing a friction bushing with a needle bearing: it is not always possible due to space or type of motion.

In a combine, Rexnord components appear in the header, threshing system, transport augers and cleaning fans. Spherical roller bearings go on shafts that withstand vibration and misalignment, while Y-housings with inserts are used at support points of secondary shafts. Friction bushings are in platform joints and adjustment mechanisms.

In seeders, Y-bearings and pillow block housings are common on metering unit shafts and depth control wheels. Dust and seed residue conditions require seals in good condition. Always check the condition of the seals during preventive maintenance.

To order combine or seeder spare parts, note the Rexnord code if visible, or take a photo of the part and where it is mounted. At MR we work with agricultural spare parts and quote via WhatsApp or email. Avoid waiting until the part seizes completely: a bearing with play or noise gives warning before failing.

To quote any Rexnord component, the most practical way is to send us via WhatsApp or email the complete code if you have it, or a photo of the part with a ruler or caliper next to it. If the code is not legible, measure inner diameter, outer diameter and width (or length for bushings) and state it in the message. Indicating the machine and model also helps.

At MR we distribute the Rexnord line for the agricultural industry from Buenos Aires, Argentina. You don't need to be an expert in nomenclature: with the part data we indicate the correct replacement. If you have another brand's code, we can also look for the Rexnord equivalent.

A common mistake when quoting is sending only a photo without measurements or size reference: this can lead to confusion between similar series. Always add at least one measurement or a reference object. Write to us via WhatsApp or email and we will respond promptly with the quote.
