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.
NMT 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. NMT 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.
