Bearing up under heavy workloads

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, advises NSK. Instead, frequent downtime and costly failures will be the likely result.

NSK’s solution to this challenge is the Agri Disc Hub, described as a cost-effective, self-lubricating bearing unit that delivers a number of major benefits to users of farming implements.

Sturdy housing

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

In the extreme

Alongside high-performance bearing technology, Agri Disc hubs are said to be 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,” states NSK.” ‘Greased for life’ Agri Disc Hub bearings are also said to provide users with maintenance-free operation.

“The design of the bearings and sealing system significantly increases service life,” adds the company. “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 promises to ensure rapid deliveries at competitive costs; even more so for custom requests. From stock, NSK Europe can offer disc diameters up to 800 mm.
