Conical roller bearings are a type of bearing used for supporting and rotating motion, widely used in industries such as automobiles, rolling mills, mines, metallurgy, and plastic machinery. The following are the usage precautions for seven types of tapered roller bearings:

1. Ensure correct specifications, dimensions, and accuracy. The size and accuracy of tapered roller bearings are crucial for their normal operation and service life. Before installation and use, it is necessary to select the appropriate bearing specifications, dimensions, and accuracy for the application scenario and load.

2. Correct installation angle. When installing tapered roller bearings, it is necessary to pay attention to the installation angle to ensure that the bearings work in the correct position and direction of rotation.

3. Keep the bearings clean. Avoid the intrusion of impurities, oil stains, and moisture to prevent them from affecting the normal rotation and rotation accuracy of the bearing. Meanwhile, during use, it is important to keep the bearings and their surroundings clean, avoid strong impacts, and use appropriate operating tools.

4. Choose the right lubricant. The selection of appropriate lubricants has a significant impact on the fatigue life, friction, wear, temperature rise, vibration, etc. of bearings. When selecting lubricants, it is necessary to consider factors such as bearing speed, operating temperature, usage environment, and application scenarios.

5. Avoid overload and imbalance. Excessive load and imbalance can lead to bearing overheating, damage, and premature failure. Therefore, when using tapered roller bearings, it is necessary to ensure that the load and rotational speed of the application meet the rated requirements of the bearing, and to minimize the eccentricity and angle of the bearing as much as possible.

6. Avoid corrosion and rust. Corrosion and rusting can accelerate bearing damage and failure. During use, attention should be paid to corrosion issues and appropriate protective measures should be taken, such as selecting corrosion-resistant bearing materials, avoiding corrosive liquids and gases, etc.

7. Monitoring and maintenance. Regular inspection and maintenance of tapered roller bearings are key to ensuring their normal operation and extending their service life. During use, attention should be paid to hearing to identify irregular operating conditions. It is recommended to use electronic condition monitoring instruments to pre detect the operation of bearings. If any abnormalities are found, they should be immediately stopped for inspection and maintenance.
