1. The Size, Direction And Nature Of The Load: the slewing drive is suitable for bearing light load, and the roller bearing is suitable for bearing heavy load and impact load.When the rolling bearing is subjected to pure axial load, thrust bearing is generally selected.When the rolling bearing is subjected to pure radial load, deep groove ball bearing or short cylindrical roller bearing are generally selected.Deep groove ball bearing, angular contact ball bearing, tapered roller bearing and self-aligning ball or self-aligning roller bearing can be used when the rotary device is subjected to pure radial load and small axial load at the same time.When the axial load is large, the angular contact ball bearing and tapered roller bearing with large contact Angle can be selected, or the radial bearing and thrust bearing can be combined together, which is especially suitable for high axial load or special requirements of large axial rigidity.

2. Allowable Speed: the type of slewing bearing drive varies greatly.Under normal circumstances, low friction, less heat bearing, suitable for high speed.The design should make every effort to work under the condition that the rotary rolling bearing is lower than its speed.

3. Rigidity: When the bearing of the rotary driving device bears load, elastic deformation will occur at the contact point between the bearing ring and the rolling body. The deformation is proportional to the load, and the ratio determines the rigidity of the bearing.Generally, bearing rigidity can be improved by pretightening the bearing.In addition, the bearing stiffness can be improved by considering the combination and arrangement of the bearing in the bearing design.

4. Centering Performance And Mounting: After the bearing is loaded into the working position, the mounting and positioning are often poor due to manufacturing error.This is often due to shaft fishing and thermal expansion and other reasons, so that the bearing bear too much load, causing early damage.The self-aligning bearing can overcome the defects caused by the installation error, so it is suitable for this kind of bearing.

5. Installation And Disassembly Of Rotary Driving Device: tapered roller bearing, needle roller bearing and tapered roller bearing, etc., belong to the type of bearing with detachable inner and outer rings (the so-called detachable bearing), which is convenient for installation and disassembly.
