In the construction machinery, the slider is almost an indispensable part. For example, the slider used to support the crane arm of the truck crane has been made of brass in the past. Now, after using the nylon slider, the service life of the MC nylon slider is increased by 4-5 times. The service life of the MC nylon slider is long, and the lubrication performance can be maintained for a long time after one-time oiling. At the same time, it has the advantages of impact resistance, vibration resistance, fatigue resistance, low noise, light weight, convenient assembly and wear resistance.
　　
　　Shaft sleeve, bearing
　　
　　Nylon, instead of copper and Babbitt alloy, is widely used in construction machinery. Features: good wear resistance and self-lubricating performance. At present, the general thermal friction coefficient is small, impact resistant, not easy to hold the shaft, fusion, and not damage the journal; long lubrication cycle, reduced maintenance, strong adaptability in harsh environment, and long service life.
