Choosing a slewing bearing involves several considerations. Here are some key factors to consider:

1. Knowledge of Mechanical Equipment: Understand the requirements of your engineering projects or machinery and equipment.

2. Carrying Ability: Choose the appropriate type of slewing bearing based on the required bearing capacity.

3. Size and Structure: The dimensions and design of the bearing should be suitable for your specific application.

4. Material Selection: The material of the bearing should be chosen based on the operating conditions.

5. Performance and Quality Assessment: Evaluate the performance and quality of the bearing.

6. Load Conditions: Information about loads, load spectra with corresponding time proportions , speed or number of swivel movements and swivel angles per time unit with corresponding load spectrum, and the circumferential force to be transmitted from the gearing are important for selecting a bearing.

7. Bearing Diameter and Other Operational Conditions: These are also crucial factors in selecting a bearing.

8. Static Load-Carrying Capacity: The determined loads are multiplied by a factor assigned to the application. The product must lie below the static maximum load curve of the selected bearing.

9. Theoretical Service Life: In the engineering of rolling bearings, theoretical service life is a well-known term. Given the many influencing factors, the nominal service life cannot be used as an absolute value in practice, but as a comparative value and design parameter.

Remember, it's always a good idea to consult with a bearing specialist or an engineer when selecting a slewing bearing for your specific application.
