Punishing Loads. Misalignment. Mechanical shock. Grit, contamination and marginal lubrication. A day in a life for bearings used in mining and quarrying industries. For the machinery and equipment used to extract, transport and process – interdependent in their purpose – access can be remote or restricted. The unexpected failure of a single component can bring an entire site to a standstill – at a significant cost. For NSK, product development and design is focused squarely on withstanding the manifold operating and environmental stresses of these applications with:

  • Increasing capacities for high loads and high speeds
  • Advanced materials for durability, wear-resistance and longer life
  • Lubrication and seal technology for smooth and clean running

NSK product solutions are designed to optimize the performance of machinery and equipment, assure predictable reliability and deliver total cost-efficiency. The operating environments for bearings in the mining and construction industries can be extremely severe:

  • Heavy loads combined with shock loads
  • Light loads with high-speed rotation
  • Heavy loads with low-speed rotation

NSK rolling bearings offer mine operators longer service life under the most challenging operating conditions, to maximize uptime and reduce maintenance costs for improved productivity at mining sites. Durability and reliability are of paramount importance for mining machinery operating in remote locations, where the failure of a single component can impact the entire operation. NSK rolling bearings are designed to high-performance standards for longer operating life, thereby reducing maintenance costs and downtime.

The recent trend towards ever-larger equipment means that repair work can become a major undertaking. NSK customers require bearings that can withstand these severe operating environments – bearings that are tough, long-lasting and offer high reliability. In order to meet these requirements, NSK optimizes mechanical bearing design in tandem with advanced material technology. The result is rolling bearings built to endure punishing conditions and outperform conventional expectations. In this way, NSK contributes to increased throughput with high-cost efficiencies while maintaining a sustainable and environmentally friendly operation in even the most rigorous mining environments.
