Advantages and disadvantages of rolling bearings compared with sliding bearings
Rolling bearings have these advantages compared with sliding bearings: the friction coefficient of rolling bearings is smaller than that of sliding bearings, and the transmission efficiency is high. Rolling bearings are made of bearing steel, while sliding bearings use more expensive non-ferrous metals. Rolling bearings have more advantages in cost. The internal clearance of the rolling bearing is very small, the processing accuracy of each part is high, and the operating accuracy is high. Due to the high transmission efficiency of rolling bearings and low heat generation, the consumption of lubricating oil can be reduced, making lubrication maintenance easier. Disadvantages of rolling bearings compared with sliding bearings: The ability of rolling bearings to bear load is much smaller than sliding bearings of the same volume. The vibration and noise of rolling bearings are relatively large, especially in the later stages of use. Compared with rolling bearings and sliding bearings, each bearing type has unique advantages and can meet specific industry needs. The two cannot completely replace each other.
