Use and classification of bearings
Bearings are important components used to support and turn rotating parts in mechanical devices, which can reduce friction between mechanical parts and make them run more smoothly. Bearings are widely used in various mechanical equipment and industrial fields, such as automobiles, aerospace, electric power, metallurgy, petroleum and so on. According to different working principles and structural forms, bearings can be divided into a variety of classification methods. The following are common bearing classifications: Rolling bearings: Rolling bearings reduce friction by rolling a rolling element (such as a ball, roller or roller) between the inner and outer rings. Common rolling bearings are deep groove ball bearings, cylindrical roller bearings, angular contact ball bearings, tapered roller bearings and so on. Plain bearing:…
