NSK high precision bearing installation steps are as follows:
( 1 ) the shaft and hole roundness, and with the corresponding accuracy requirements in accordance with the vertical shoulder block bearing.
( 2 ) to rotate the ring interference degree accurately calculated, but also accurately calculate a match fixing ring suitable quantity.
( 3 ) in such as high-speed operation, condition of bearing and high working temperature, special attention should be paid to the rotating ring, not too loose, to prevent the eccentric, but not with the fixed ring gap, to prevent the load and vibration excitation in the deformation of the ring.
( 4 ) the small ring interference fit condition, in order to meet the surface precision of both the high, low roughness, or difficult, more difficult to remove the installation, also need to consider the spindle thermal expansion.
( 5 ) double angular contact ball bearing spindle with double, most of the load is light, such as the relatively large amount of interference, the axial preload, will clearly too large, adverse effects. The use of double row cylindrical roller bearings and tapered roller bearing spindle, the load is relatively large, so the greater interference.
The NSK bearing installation method, it shows high precision NSK bearings installed how complex, so everyone in the operation of the process should be more circumspect.
