^{The shaft is supported by bearings, and the shaft segment that cooperates with the bearing is called the shaft. The shaft rod is the assembly benchmark of the shaft, and their accuracy and surface quality are generally required to be high. The technical requirements are generally formulated according to the main function and working conditions of the shaft, and usually include the following items:}

^{(a) Surface roughness
Generally, the surface roughness of the shaft diameter matched with the transmission part is Ra2.5~0.63μm, and the surface roughness of the support shaft diameter matched with the bearing is Ra0.63~0.16μm.}

^{(b) Mutual position accuracy
The position accuracy requirements of shaft parts are mainly determined by the position and function of the shaft in the machine. Usually, it is necessary to ensure the coaxiality requirements of the journal of the assembly transmission part to the support journal, otherwise the transmission accuracy of the transmission part (gear, etc.) will be affected, and noise will be generated. For ordinary precision shafts, the radial runout of the matching shaft section to the bearing journal is generally 0.01~0.03mm, and the high-precision shaft (such as the main shaft) is usually 0.001~0.005mm.}

^{(c) Geometric accuracy
The geometric accuracy of shaft parts mainly refers to the roundness and cylindricity of the journal, outer cone surface, Morse taper hole, etc., and its tolerance should generally be limited within the dimensional tolerance range. For the inner and outer circular surfaces with high precision requirements, the allowable deviation should be marked on the drawing.}

^{(d) Dimensional accuracy
In order to determine the position of the shaft, the journal that acts as a support usually requires high dimensional accuracy (IT5~IT7). The dimensional accuracy of the journal for assembling transmission parts is generally low (IT6~IT9).}
