The installation of seven types of tapered roller bearings requires attention to the following:

1. Ensure cleanliness: Before installing the bearings, they should be cleaned and the mounting seat checked for damage or deformation. Ensuring the cleanliness of bearings and their surrounding components can reduce wear and friction.

2. Inspection direction: Ensure that the bearings are installed in the correct direction to avoid inconsistency between the axial load direction and the bearing installation direction, which will have a significant impact on the performance and service life of the bearings.

3. Use specialized tools: When installing bearings, it is best to use specially designed tools to ensure the accuracy and precision of the installation position, and to prevent situations of looseness or tightness.

4. Pre pressurization: During the installation process, press on the end face of the bearing and ensure that there is no gap to ensure the stability and normal operation of the bearing.

5. Good lubrication: Ensure that the bearings have sufficient lubrication to avoid damage due to poor lubrication. Choose the appropriate lubricant and lubricate according to the correct method and cycle to ensure the long-term stable operation of the bearing.

6. Fixation and calibration: After installation, use tools to fix the bearings to prevent loosening or shaking. Afterwards, a rotation test is required to check whether the rotation of the bearing is normal.

7. Prevent excessive compression: When installing bearings, excessive compression or looseness should be avoided to ensure the normal operation and lifespan of the bearings. The clearance of bearings should be determined based on the operating conditions and the size of the interference fit, and can be adjusted by pressing and loosening.
