Quarrying, Mining, & Construction
Mining and construction equipment are often used in remote areas, such as mountains, deserts, or even 2,000 meters below ground. Widely different machines are used—from crushers, grinders, and excavators to sifters, screens, loaders, and transporters, with many operating continuously. This 24/7 operation means that breakdowns have a major impact on production, with repair often difficult due to the equipment’s size.
Bearings in mining and construction face extremely challenging conditions including:
- Heavy loads with impacts/shocks
- Light loads with high-speed rotation
- Heavy loads with low-speed rotation
As machines critical to building society, bearings in mining and construction equipment must be tough, long-lasting, and highly reliable.
NSK combines the very latest in design with our core technologies in materials, lubrication, and analysis to offer bearings that go beyond the limits of convention. NSK bearings provide both long life and high allowable speeds, increasing productivity and lowering maintenance costs in even the harshest sites while working toward more environmentally friendly operations.
NSK Experience & Technology
As mining and construction equipment operate in sites around the world, most bearings used in the industry are standardized by ISO and take maintenance into account. Never settling, NSK developed bearings with the top specs in the world.
- NSKHPS™ High Performance Standard Bearings for Industrial Machinery: Spherical Roller Bearings
With the latest cage designs and special surface treatments, NSKHPS bearings use the latest materials for greatly increased load capacity and longer life. - EM Series Cylindrical Roller Bearings
A machined one-piece cage allows for an increase in both roller size and the number of rollers, greatly improving function in this new generation of CRBs with exceptionally high load capacity and long life.
NSK continues its development efforts day-in and day-out to provide the mining and construction industries with the utmost in function, performance, and reliability.
Digging, Drilling and Blasting the Ore
NSK Bearings are used in some of the toughest terrain and inaccessible locations of a mining site. Whether it's digging an access tunnel, removing the ore, or attaining mineral deposits drilling machinery, bearings used in draglines and shovels need to be reliable. NSK technology, service and experience can help you maintain your production momentum.
Crushers for quarrying & mining
Achieving longer life from Quarrying conveyors
Stack, Doze or Carry - NSK Bearings Help You Lighten the Load of Maintenance
Heavy loads, shock loads, vibration, misalignment and debris all contribute to machinery wear, but NSK bearings can help lighten the load of maintenance with specifically designed vibration and wear resistant bearings helping you to extend your plant production life.
NSK has worked with equipment manufacturers, contractors and mine operators worldwide to create bearings which meet their working needs, and we will continue to develop and invest in new technology to ensure your machinery continues to perform.
Transportation around the mining and quarrying sites - conveyors, dumper trucks, loaders, reclaimers, mobile plant and much more...
Crush, grind, screen, blast...It's a tough life to prepare, separate & enrich minerals
The very harsh environments of the mineral preparation, separation and enrichment processes demand that machinery is pushed to the limits with weight and vibration, and contamination is a constant problem.
By understanding and working with equipment manufacturers and mine operators (for static and mobile plant) over the years NSK has been able to develop and design bearings which continue to perform through permanent states of misalignment, shock loads and vibration, to ensure that your machinery keeps performing even under such extreme conditions.
We can advise and help you with fitting, lubrication, sealing and bearing selection to suit your needs.
