1.Bearing model selection: Choose the appropriate bearing model based on the operating conditions and load requirements. Ensure that the bearing can meet the required load, speed, and environmental conditions.

2.Bearing clearance selection: Select the appropriate clearance based on the bearing's operating conditions, speed, temperature, etc. The choice of clearance will affect the bearing's performance and lifespan.

3.Grease selection: Select the suitable grease based on the bearing's speed, temperature resistance, noise requirements, etc. Understand the performance characteristics of different greases to ensure proper lubrication of the bearing.

4.Bearing sealing type selection: Select the appropriate bearing sealing type based on the lubrication method. For oil lubrication, you can use form seals, and for grease lubrication, you can choose dust shields or rubber seals. Consider factors such as dust prevention and starting torque when making the selection.

In addition, there are some general usage precautions:

1.Ensure the correct installation of the bearing, preventing any damage during assembly. The fit between the shaft and the bore should be appropriate, avoiding overly tight or loose fits.

2.Pay attention to the lubrication of the bearing during use. Regularly add an appropriate amount of grease or lubricating oil to maintain proper lubrication.

3.Avoid overloading the bearing, ensuring that the load remains within the rated load range of the bearing.

4.Regularly inspect the working condition of the bearing. Pay attention to any abnormal noise, vibration, or temperature rise, and take timely maintenance measures or replace the bearing if necessary.

Finally, choose the appropriate bearing specifications, precision, and fit based on the usage environment and conditions to ensure the bearing's lifespan and reliability.
