Drilling Equipment:

• Function: Bearings support drill bits, drive shafts, and rotating machinery, enabling them to handle high loads, speeds, and extreme conditions like high pressure and corrosion.
• Types: Rolling bearings (e.g., deep groove ball bearings, cylindrical roller bearings), sliding bearings, and corrosion-resistant bearings are commonly used.

Pumps and Compressors:

• Function: Bearings ensure smooth operation of pumps and compressors, which are critical for fluid and gas movement, by reducing friction and enhancing efficiency.
• Types: Spherical roller bearings and thrust bearings are often employed to manage multi-directional loads.

Pipelines:

• Function: Bearings in pipeline systems support pumps and compressors, ensuring efficient and reliable fluid transport under high-pressure conditions.
• Types: Self-lubricating and ceramic bearings are preferred for their durability and reliability.

2. Wind Energy (Wind Power Generation)

Wind turbines rely on high-performance bearings to convert wind energy into electricity efficiently and reliably.

애플리케이션:

Main Shaft Bearings:

• Function: These bearings support the turbine’s main shaft, enduring significant loads from wind forces, including lateral, vertical, and torque stresses.
• Types: Spherical roller bearings, angular contact ball bearings, and cylindrical roller bearings are commonly used.

Gearbox Bearings:

• Types: Cylindrical roller bearings and needle roller bearings are typical choices.

Generator Bearings:

• Function: These bearings support the generator’s high-speed rotation, requiring high precision and resistance to mechanical stress.
• Types: High-precision rolling bearings, ceramic bearings, or self-lubricating bearings are often used.

3. Solar Energy

While bearings are less prevalent in solar systems compared to other energy sectors, they are vital in specific applications like solar trackers and thermal power plants.

애플리케이션:

Solar Trackers:

• Function: Bearings enable precise movement of solar panels to track the sun, maximizing energy absorption.
• Types: Deep groove ball bearings, angular contact ball bearings, and self-aligning bearings are commonly used.

Solar Thermal Systems:

• Function: Bearings in turbines and concentrators must withstand high temperatures and pressures in solar thermal power plants.
• Types: Ceramic bearings or high-temperature lubricated bearings are often employed.

4. Nuclear Energy

In nuclear power plants, bearings are critical for supporting pumps, valves, generators, and turbines, often operating under extreme conditions like high temperatures, pressures, and radiation.

애플리케이션:

Pump Bearings:

• Function: These bearings ensure stable operation of cooling pumps under high-temperature, high-pressure, and low-lubrication conditions.
• Types: High-temperature and radiation-resistant bearings made from special alloys or ceramics are used.

Turbine Generator Bearings:

• Function: Bearings reduce friction and wear in turbine generators, maintaining efficient power production.
• Types: Rolling or sliding bearings made from high-performance materials are typical.

5. Hydropower

Bearings are vital in hydropower systems, supporting turbines and generators that convert water flow into electricity.

애플리케이션:

Turbine Generator Bearings:

• Function: These bearings handle high loads and endure constant water flow, directly impacting generator efficiency and stability.
• Types: Large cylindrical roller bearings and spherical bearings are commonly used.

Speed Governor Bearings:

• Function: Bearings in speed governors ensure precise control of turbine speed, requiring high accuracy and stability.
• Types: High-precision rolling bearings are typically employed.

6. Coal and Other Energy Sources

In the coal industry, bearings are widely used in mining equipment, transmission systems, and coal mills, operating under high-load and high-vibration conditions.

애플리케이션:

Coal Mining Equipment:

• Function: Bearings support high-speed rotating parts in excavators, crushers, and conveyors, reducing wear and energy loss.
• 유형: 원통형 롤러 베어링과 깊은 홈 볼 베어링과 같은 고하중 베어링이 일반적으로 사용됩니다.
