The NTN insert bearing of the HEAVY DUTY DISC BEARING INSERTS series with hexagonal bore is a sealed bearing unit that mounts directly on the hexagonal shaft of seeding discs. It absorbs combined radial and axial loads, the lateral thrust of the soil and the contamination typical of field work. MR Accesorios Industriales sells this line for bearing replacement in seeders and tillage equipment.

The designation of these inserts is read in blocks: the initial number indicates the size of the hexagonal bore, the letters AH identify the hex bore variant and the suffix V indicates the reinforced sealing for heavy duty service. Examples in the series, 2AH08-1.1/4V2V2 and 3AH10-1.5/8V2V2, show that structure: size number, hex bore, and the final digits that define the seal type and unit configuration. By sending the complete code, MR quotes the exact reference.

These inserts are used in seeding discs of coarse and fine grain seeders, in no-till seeding units and in tillage equipment with hexagonal shafts. In the Argentine field they appear in seeding machines of the main brands, where the bearing works buried, with mud, dust and stubble. They are also used in implements that rotate on hexagonal shafts and require a compact, sealed unit with high load capacity.

To select the correct insert, take into account the size of the hexagonal bore of the shaft, the outer diameter and the width of the unit, as well as the seal type. During assembly, check that the hex shaft is clean and free of burrs, that the insert seats without blows and that lubrication is adequate for work with contamination. Disc alignment and seal adjustment are key for the V seal to work well and last.

Interchangeability between brands is handled by dimensions and bore type: an insert with a hex bore from another brand can be replaced by the equivalent NTN if the bore, outer diameter, width and seal configuration match. When the customer brings the code of the original part or an unidentified sample, at MR Accesorios Industriales we cross-reference it and indicate the corresponding NTN reference. Interchangeability is always confirmed against the actual measurements of the unit.

If you have the insert code, the seeder model or the hexagonal shaft measurement, send it by WhatsApp to MR Accesorios Industriales and we will quote it shortly. You can also send a photo of the part or the housing so we can identify the exact reference. MR solves bearing replacement for agricultural machinery.
