Para los rodamientos utilizados en el sector agrícola no faltan peligros potenciales, como la humedad, el polvo del suelo, los fertilizantes corrosivos y las cargas de impacto muy elevadas (como las generadas por las piedras). Sin embargo, el diseño robusto de los rodamientos y el sellado altamente efectivo de los bujes de disco Agri de NSK los convierten en una opción comprobada en condiciones operativas extremas. Fabricadas en Alemania, estas unidades innovadoras son una opción popular para implementos agrícolas comunes, como gradas de discos cortos, sembradoras y cortadoras de martillos.

Extremely harsh working conditions, along with high-pressure washing routines, place a raft of demands on the bearings and seals found in equipment for the agriculture industry. A low-quality bearing will not be sufficiently robust in its design or performance levels to provide the uptime necessary for reliable and productive operation. Instead, frequent downtime and costly failures will be the likely result.

NSK’s solution to this challenge is the Agri Disc Hub, a cost-effective, self-lubricating bearing unit that delivers a number of major benefits to users of farming implements. High-performance Agri Disc Hubs feature double-row angular-contact ball bearings that can support high axial and radial loads, while the meticulously devised configuration locates the bearings within a sturdy housing that connects directly (and simply) to the implement via an integrated flange.

Importantly, NSK can offer fast, Europe-wide availability of Agri Disc Hubs as manufacturing takes place in Germany. The Munderkingen facility can boast almost 70 years of high-quality production output.

Alongside high-performance bearing technology, Agri Disc hubs are equipped with a highly effective sealing system for robust protection against extreme condition applications. This comprehensive system is a combination of labyrinth and contact seal designs, which serves to prevent both the ingress of contaminants and the escape of grease. ‘Greased for life’ Agri Disc Hub bearings provide users with maintenance-free operation.

The innovative design of the bearings and sealing system significantly increases service life. Even under extreme stress, Agri Disc Hub bearings – and thus the implement which they serve – grant a service life that is several times beyond that of other commercially available solutions, while their modularity means they can be adapted very quickly to individual user requirements. In such instances, flexible manufacturing at the Munderkingen plant ensures rapid deliveries at competitive costs, even more so for custom requests.

Fundada en 1954, la planta de Munderkingen comenzó produciendo rodamientos para un fabricante líder de maquinaria para el sector agrícola. La adquisición de la planta por NSK en 1990 condujo pronto a la introducción de instalaciones de producción altamente flexibles que crean las condiciones necesarias para fabricar incluso lotes pequeños de rodamientos específicos para cada cliente con alta eficiencia. En stock, NSK Europe puede ofrecer diámetros de disco de hasta 800 mm.
