Needle roller bearings are used in petroleum extraction equipment, such as pumping units and drilling equipment. With their small cross-sectional size and high load-bearing capacity, needle roller bearings can effectively support the rotating parts of the equipment, reduce friction, and improve equipment operation efficiency and stability. In the oil transportation process, the power system and loading and unloading equipment of ships also use needle roller bearings to ensure smooth transportation. In addition, in various types of machinery used in petroleum refining, needle roller bearings can adapt to complex working conditions such as high temperature and high load, assist in the continuous operation of equipment, and play a key role in maintaining the normal production process of the petroleum industry.
