1.1 Design and ClassificationRolling bearings generally consist of two ringselements, and a cage, and they are classified inbearings or thrust bearings depending on the dof the main load. In addition, depending on therolling elements, they are classified into ball bor roller bearings, and they are further segregdifferences in their design or specific purpose.The most common bearing types and nomencbearing parts are shown in Fig.1.1, and a
classification of rolling bearings is shown in Fig
1.2 Characteristics of Rolling Bearings
Compared with plain bearings, rolling bearinthe following major advantages:(1) Their starting torque or friction is low
difference between the starting torque and torque is small.
