In comprehensive mining equipment, 70% -80% of accidents are concentrated in the shearer, and 50% of shearer accidents are mechanical failures caused by gear damage due to bearing failure.

The various types of coal machine bearings we develop and produce represent industry-leading anti-wear and durability performance. The service life of key parts bearings can reach 15000 hours, with super strong load capacity, greatly reducing the rate of bearing damage. Easy installation and excellent impact resistance. Good lubrication and sealing ensure a smaller friction coefficient, doubling the service life. Many modern large-scale construction machinery, such as asphalt mixing equipment, stabilized soil mixing equipment, and combined crushers, are of large scale, with each part weighing tens to hundreds of tons. Moreover, most construction machinery operates in harsh environments such as mud, gravel, rainwater, and snow, and its technical condition is bound to decline faster than other machinery, The fit between parts will experience varying degrees of looseness, wear, rust, and scaling. The fit properties of various connectors, the positional relationship between parts, and the coordination of mechanism work will be affected to varying degrees, resulting in a decrease in performance indicators such as power, economy, and reliability, and even causing machine accidents.

Therefore, it is necessary to pay attention to the selection and technical maintenance of components, especially bearings, in construction machinery. A high-quality bearing can improve the working life and efficiency of construction machinery, thereby improving economic benefits.
