Many people don't know how to choose the right slewing ring correctly. When they want to buy or customize a slewing ring but don't know which model to use, here's a basic step for everyone to briefly introduce slewing ring selection:
1. According to the environment of use, the maximum load (axial load, radial load, overturning moment) that the slewing bearing is subjected to at rest. Use this maximum load as a static rating.

2. Static safety factor according to the type of machine installed.

3. Referring to the Wanda Slewing Bearing Catalog, first select the slewing bearing model and determine the formula for calculating the static reference loads Fa' and M. ".

4. Calculate the static reference loads Fa' and M'.

5. Find the static load curve corresponding to the slewing bearing of the selected model in the Wanda Slewing Bearing Catalogue and mark it in the figure (Fa', M')

6. Check if the coordinate point is within the static load permission.

7. Check the load carrying capacity of the bolt.

8. Complete the initial selection.
