Pour les roulements utilisés dans le secteur agricole, les dangers potentiels ne manquent pas, notamment l'humidité, la poussière du sol, les engrais corrosifs et les charges de choc très élevées (telles que celles générées par les éclats de pierre). Cependant, la conception robuste des roulements et l'étanchéité très efficace des moyeux NSK Agri Disc Hubs en font un choix éprouvé dans des conditions de fonctionnement extrêmes. Fabriqués en Allemagne, ces unités innovantes sont un choix populaire pour les outils agricoles courants tels que les déchaumeurs à disques courts, les semoirs et les faucheuses à fléaux.

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.

Fondée en 1954, l'usine de Munderkingen a débuté sa vie en produisant des roulements pour un fabricant leader de machines pour le secteur agricole. Le rachat de l'usine par NSK en 1990 a rapidement conduit à l'introduction d'installations de production très flexibles qui créent les conditions nécessaires pour fabriquer même de petits lots de roulements spécifiques au client avec une efficacité élevée. En stock, NSK Europe peut proposer des diamètres de disque allant jusqu'à 800 mm.
