Application of Roller Bearings in Extreme Working Environments

1. High Load and Misalignment Tolerance
Spherical roller bearings support heavy radial and axial loads while compensating for shaft misalignment up to ±0.5° (even 1°30' under low loads) without compromising load capacity . This makes them indispensable in mining, construction, and steel mills, where equipment faces dynamic stresses and alignment shifts due to uneven loading .

2. High-Temperature Resistance
Designed with heat-treated materials, these bearings operate stably at temperatures up to 200°C (392°F) . In steel plants and energy sectors like oil drilling, bearings endure heat from rolling mills or high-pressure drilling equipment, ensuring longevity and reduced downtime .

3. Contamination and Corrosion Resistance
In polluted or corrosive environments (e.g., mining, pulp/paper industries), sealed spherical roller bearings with specialized lubricants prevent ingress of dust, moisture, and corrosive agents. For example, FAG’s vibratory machinery bearings withstand contamination and humidity in road rollers or saw frames . Eich’s spring bush bearings further enhance dirt resistance in conditions .

4. Vibration and Shock Absorption
Vibratory screens, crushers, and railway traction motors subject bearings to high-impact loads and centrifugal forces. Spherical roller bearings with robust cages and optimized geometries mitigate friction spikes and temperature rises caused by vibrations .

5. Specialized Environments
For vacuum or cleanroom settings (e.g., semiconductor manufacturing, aerospace), custom materials like low-outgassing lubricants and anti-corrosion coatings are critical. NBC’s high-temperature bearings, for instance, adapt to vacuum furnaces and semiconductor tools .

6. Extended Maintenance Intervals
In railway and wind energy applications, grease-lubricated tapered roller bearings reduce maintenance frequency, even under prolonged high-speed operation .
