Mining operations are important to the improvement and preservation of our daily living, providing resources used to create electricity, roads, and communities. Mines are typically located far from where most people work, often in mountainous or arid regions, and can be found as much as 2,000 meters below ground. The equipment used is varied and can be operated continuously, 24 hours a day for 7 days a week. The mining process starts with the breaking up of the rock face and continues through the processing of the minerals, utilizing such technology as cutting equipment, screening machinery, stockpiling equipment and conveying equipment.
Much like mining operations, construction operations play a pivotal role in the improvement of society. The construction industry safely and effectively makes our lives more comfortable and efficient. From skyscrapers to highways to sewers, construction machinery, such as excavators, dozers, and cranes, help to build a better future.
The operating environments for bearings in the mining and construction industries can be extremely severe. One or more of the following can arise:
- heavy loads combined with shock loads
- light loads with high speed rotation
- heavy loads with low speed rotation
Durability and reliability are of paramount importance for mining, quarrying and construction machinery operating in remote locations such as mountains and deserts, where failure of a single component can impact the entire operation.
NSK has applied state-of-the-art technlogy to exceed the life and limiting speed of conventional bearings. Our superior bearings offer higher limiting speed and longer operating life, thereby reducing maintenance costs for mine and quarry operators.
